1
00:00:03,040 --> 00:00:06,160
Speaker 1: Welcome to Stuff to Blow Your Mind from housetop works

2
00:00:06,200 --> 00:00:22,799
Speaker 1: dot com. Hey, hey, hey, welcome to stuff to Blow

3
00:00:22,840 --> 00:00:26,400
Speaker 1: your Mind. I guess uh my name is Robert Lamb.

4
00:00:26,440 --> 00:00:28,240
Speaker 1: It says it right here on the side of my

5
00:00:28,920 --> 00:00:34,120
Speaker 1: cryo tank. Yeah, I'm Christian Sager. That's it, right, that

6
00:00:34,200 --> 00:00:36,000
Speaker 1: was the name I was using. Yeah, that's what it

7
00:00:36,040 --> 00:00:39,559
Speaker 1: says on your cryo tank. You like Christian? Here we are?

8
00:00:40,560 --> 00:00:45,600
Speaker 1: Where where are we? Let me check the read out here? Okay, good,

9
00:00:45,640 --> 00:00:49,520
Speaker 1: we're we should be We should have arrived at the

10
00:00:49,560 --> 00:00:53,920
Speaker 1: Medusa Nebula, which is where we set out for two

11
00:00:53,960 --> 00:00:56,560
Speaker 1: thousand years ago. Yeah, I'm remembering this now. It was

12
00:00:57,680 --> 00:01:01,760
Speaker 1: light years, so we were We've been alive for almost

13
00:01:01,760 --> 00:01:06,040
Speaker 1: two thousand years, well something like alive. We've been suspended

14
00:01:06,800 --> 00:01:10,600
Speaker 1: in a state of suspended animation in these tanks. Uh,

15
00:01:10,640 --> 00:01:14,000
Speaker 1: perhaps even before the the ships set out, So maybe

16
00:01:14,000 --> 00:01:15,840
Speaker 1: it's more than two thousand years, because it took us

17
00:01:15,840 --> 00:01:18,440
Speaker 1: around two thousand years for this ship to reach the

18
00:01:18,440 --> 00:01:22,280
Speaker 1: Medusa Nebula. And before that, I seem to remember, we

19
00:01:22,280 --> 00:01:28,640
Speaker 1: were frozen along with Joe awaiting the wait, where is Joe? Joe?

20
00:01:28,760 --> 00:01:32,399
Speaker 1: Who's Joe Joe? We had another podcast partner, and it

21
00:01:32,520 --> 00:01:34,880
Speaker 1: was his name was Joe, Joe McCormick. Oh, look it

22
00:01:34,920 --> 00:01:37,440
Speaker 1: says it right here on this cryotank. Let's opened this

23
00:01:37,440 --> 00:01:42,240
Speaker 1: one as well. It's just fingernails and hair. Uh, there

24
00:01:42,319 --> 00:01:45,520
Speaker 1: was more to him than that, as I recall. Um,

25
00:01:45,560 --> 00:01:49,960
Speaker 1: well I don't, I don't recall it, Joe, but um,

26
00:01:50,000 --> 00:01:51,960
Speaker 1: but you know, I mean, we can always eat the

27
00:01:52,000 --> 00:01:54,520
Speaker 1: fingernails and hair if there aren't any, you know, rations

28
00:01:54,560 --> 00:01:57,360
Speaker 1: aboard this thing. Oh yeah, but maybe we woke up early.

29
00:01:57,400 --> 00:01:59,800
Speaker 1: It should do it we set out to do. Maybe

30
00:02:00,040 --> 00:02:04,200
Speaker 1: maybe we should look at this Medusa nebula. Yeah, yeah,

31
00:02:04,360 --> 00:02:07,880
Speaker 1: I I'm remembering more. Yeah, because this was the topic

32
00:02:07,960 --> 00:02:09,760
Speaker 1: that made us decide to abandon the list of the

33
00:02:09,880 --> 00:02:12,559
Speaker 1: rest of our lives and to turn it across the cosmos.

34
00:02:12,639 --> 00:02:15,480
Speaker 1: And well, it's so hauntingly beautiful. Of course you would

35
00:02:15,480 --> 00:02:18,320
Speaker 1: just say, screw everything, let's just do this. Yeah. It's

36
00:02:18,320 --> 00:02:22,160
Speaker 1: one thing to see these wonderful NASA images of the Nebula.

37
00:02:22,280 --> 00:02:23,920
Speaker 1: We wanted to get up close and personal and use

38
00:02:24,000 --> 00:02:26,640
Speaker 1: these special fancy goggles to look at it from within

39
00:02:26,720 --> 00:02:29,400
Speaker 1: the nebula itself, and like the monster from which it

40
00:02:29,480 --> 00:02:31,919
Speaker 1: is named, once you look at it you then die.

41
00:02:32,160 --> 00:02:34,040
Speaker 1: Maybe that's what happened to Joe. It could be maybe

42
00:02:34,080 --> 00:02:36,280
Speaker 1: Joe turned to stone. Yeah. Maybe we got here early

43
00:02:36,360 --> 00:02:38,200
Speaker 1: and he just woke up on time. So maybe it's

44
00:02:38,200 --> 00:02:40,640
Speaker 1: way more than two thousand years. All right, So let's

45
00:02:40,720 --> 00:02:43,560
Speaker 1: let's refresh ourselves because it's been a while. I'm hazy

46
00:02:43,680 --> 00:02:46,680
Speaker 1: on this whole thing. So the Medusa nebula, that's just

47
00:02:47,240 --> 00:02:51,480
Speaker 1: very pretty nebula that we were able to not we

48
00:02:51,760 --> 00:02:55,400
Speaker 1: you and I, but uh, in fact, the European Space Organization,

49
00:02:55,440 --> 00:02:59,760
Speaker 1: and we're able to get some really beautiful shots of

50
00:03:00,320 --> 00:03:03,600
Speaker 1: from Earth. They have telescope centers in Chili that they

51
00:03:03,680 --> 00:03:06,400
Speaker 1: used to do this, So I guess, like I'll try

52
00:03:06,440 --> 00:03:11,919
Speaker 1: to describe it. Uh, it's this gorgeous mass of colorful

53
00:03:12,000 --> 00:03:16,560
Speaker 1: gases floating around in space. I mean, it's part of

54
00:03:16,600 --> 00:03:18,919
Speaker 1: a galaxy. It's not even a full galaxy, but it's

55
00:03:19,200 --> 00:03:22,480
Speaker 1: blues and yellows and reds and greens, and they're all

56
00:03:22,520 --> 00:03:27,079
Speaker 1: kind of swirling around together, and they're these super hot,

57
00:03:27,720 --> 00:03:32,320
Speaker 1: bright blue stars in the center of everything. Yeah, one

58
00:03:32,320 --> 00:03:36,960
Speaker 1: in particular does look like an eye. Yeah. Yeah, I

59
00:03:37,000 --> 00:03:39,800
Speaker 1: suspect that's where the idea for the whole Medusa thing

60
00:03:40,000 --> 00:03:44,920
Speaker 1: came from. So it's so named because of the colorful gases. Uh.

61
00:03:45,000 --> 00:03:48,200
Speaker 1: And it looks kind of like the Medusa monster, which

62
00:03:48,520 --> 00:03:50,640
Speaker 1: you know we like monsters on the show. In fact,

63
00:03:50,680 --> 00:03:53,360
Speaker 1: you've done work on the Medusa before. I believe I have.

64
00:03:53,720 --> 00:03:56,160
Speaker 1: Two thousand years ago you did a video, babe, remember that.

65
00:03:56,400 --> 00:03:59,200
Speaker 1: So I'm sure those signals are bouncing around the coffmos.

66
00:03:59,280 --> 00:04:03,680
Speaker 1: Maybe they still have YouTube out here, but they there's

67
00:04:03,920 --> 00:04:06,520
Speaker 1: they look like snakes, right, Like these these tendrils of

68
00:04:06,560 --> 00:04:09,800
Speaker 1: gases look like different types of snakes. They were referred

69
00:04:09,800 --> 00:04:15,160
Speaker 1: to as serpentine filaments. And each type of elemental gas

70
00:04:15,480 --> 00:04:19,080
Speaker 1: produces a different color, right, So those reds those are hydrogen.

71
00:04:19,520 --> 00:04:22,359
Speaker 1: The greens are from oxygen, and the oxygen is particularly

72
00:04:22,360 --> 00:04:28,040
Speaker 1: important to this specific nebula. And these are planetary nebula.

73
00:04:28,080 --> 00:04:31,200
Speaker 1: We need to make that distinction. Um. But basically, this

74
00:04:31,320 --> 00:04:36,279
Speaker 1: is the mass being objected from a star nearby, and

75
00:04:36,360 --> 00:04:40,560
Speaker 1: that's what's making these serpentine structures. So what what exactly

76
00:04:40,600 --> 00:04:44,120
Speaker 1: is a planetary nebula? Well, as I recall is my

77
00:04:44,800 --> 00:04:47,640
Speaker 1: is all my memories come back online here. I recall

78
00:04:47,720 --> 00:04:50,840
Speaker 1: that a planetary nebula's heart is a very old star

79
00:04:51,000 --> 00:04:53,560
Speaker 1: and in terms of stellar age, so nothing compared to

80
00:04:53,600 --> 00:04:57,039
Speaker 1: the mere few thousand years they were talking about with

81
00:04:57,080 --> 00:04:59,680
Speaker 1: our journey. Here, this is a star. This is a

82
00:04:59,720 --> 00:05:03,640
Speaker 1: star as last phase before it transforms into a white dwarf,

83
00:05:04,200 --> 00:05:07,400
Speaker 1: specifically a star. This between one to eight times the

84
00:05:07,440 --> 00:05:09,920
Speaker 1: size of our Sun when it is worn. That's right,

85
00:05:09,960 --> 00:05:14,000
Speaker 1: because we used our Sun as like a measurement system

86
00:05:14,080 --> 00:05:17,960
Speaker 1: for all other stellar bodies, right, so anything that's like

87
00:05:18,240 --> 00:05:21,720
Speaker 1: we use our Sun's size and mass really and to

88
00:05:21,920 --> 00:05:25,680
Speaker 1: determine stellar age and and other you know, measurements. Typically

89
00:05:25,720 --> 00:05:28,240
Speaker 1: these nebula have a radius of one light year with

90
00:05:28,279 --> 00:05:32,080
Speaker 1: the gas of about thirty percent of our Sun. So this, uh,

91
00:05:32,160 --> 00:05:34,800
Speaker 1: this phase of its life CEC, which is short compared

92
00:05:34,880 --> 00:05:38,760
Speaker 1: to a star's life, but it's still thousands of years long. Yeah,

93
00:05:38,880 --> 00:05:42,680
Speaker 1: I mean it's uh right again, we're getting into that

94
00:05:42,800 --> 00:05:46,080
Speaker 1: scale thing again, right, like the tiniest of life that

95
00:05:46,120 --> 00:05:49,720
Speaker 1: only lives for like a couple of human years at

96
00:05:49,720 --> 00:05:52,640
Speaker 1: the bottom of Earth's oceans. And then there's the Medusa

97
00:05:52,720 --> 00:05:57,640
Speaker 1: nebula that it's hundreds of thousands of of years. Uh,

98
00:05:57,680 --> 00:06:02,159
Speaker 1: and it's all because of gravity. Uh. So gravity really

99
00:06:02,800 --> 00:06:05,880
Speaker 1: is pushing in on these stars and on all stars,

100
00:06:05,960 --> 00:06:09,400
Speaker 1: and to keep them from collapsing on themselves, they maintain

101
00:06:09,440 --> 00:06:14,159
Speaker 1: a high internal gas pressure by creating energy through nuclear fusion.

102
00:06:14,240 --> 00:06:17,479
Speaker 1: You know, that's how stars work. Uh. And it's when

103
00:06:17,520 --> 00:06:21,320
Speaker 1: all those available fuels run out, the star becomes unstable

104
00:06:21,600 --> 00:06:24,360
Speaker 1: and so it just starts shedding off all these different

105
00:06:24,360 --> 00:06:28,080
Speaker 1: gaseous layers. That's what we're seeing here with the planetary nebula.

106
00:06:28,440 --> 00:06:33,360
Speaker 1: This expansion is proportional to the distance from the central star, right,

107
00:06:33,400 --> 00:06:36,760
Speaker 1: so the amount of gases when we see them emanating outwards,

108
00:06:36,760 --> 00:06:39,680
Speaker 1: they're all actually coming from one central star. You know.

109
00:06:39,720 --> 00:06:42,760
Speaker 1: Anytime that I've covered the stars in the past, and

110
00:06:42,800 --> 00:06:45,160
Speaker 1: you know the life cycle of stars, how they're born,

111
00:06:45,279 --> 00:06:47,800
Speaker 1: how they die. I often think of it in terms

112
00:06:47,839 --> 00:06:50,919
Speaker 1: of like a corporation or a business, you know, like

113
00:06:50,960 --> 00:06:55,080
Speaker 1: they used to have an older there um where you

114
00:06:55,600 --> 00:06:59,840
Speaker 1: see these these just gigantic industries just building up power

115
00:07:00,080 --> 00:07:04,200
Speaker 1: and energy, and it reaches this point of just instability

116
00:07:04,240 --> 00:07:08,400
Speaker 1: where things fall apart, things collapse, things explode, just like

117
00:07:08,520 --> 00:07:12,720
Speaker 1: you see with with various businesses out there. And that's

118
00:07:12,800 --> 00:07:15,120
Speaker 1: why these are so important to look at, right and

119
00:07:15,120 --> 00:07:17,360
Speaker 1: and it's probably how we got funding to to fly

120
00:07:17,480 --> 00:07:21,160
Speaker 1: out here anyways. Is that we're basically talking about sun

121
00:07:21,160 --> 00:07:24,680
Speaker 1: death here, and so by observing a planetary nebula and

122
00:07:24,680 --> 00:07:26,400
Speaker 1: the gases that come off of it and all the

123
00:07:26,480 --> 00:07:30,280
Speaker 1: chemicals involved, we understand more about our own son and

124
00:07:30,400 --> 00:07:33,240
Speaker 1: it's evolutionary process and what's going to happen to it

125
00:07:33,280 --> 00:07:38,040
Speaker 1: and subsequently us. Yeah, that sun business star business is

126
00:07:38,080 --> 00:07:41,120
Speaker 1: the business upon which it is kind of our planet depends. Yeah,

127
00:07:41,160 --> 00:07:43,600
Speaker 1: And to use your metaphor, it's kind of like getting

128
00:07:43,600 --> 00:07:46,280
Speaker 1: an m b A and studying how corporations fall apart,

129
00:07:46,360 --> 00:07:48,880
Speaker 1: so that you know when to jump ship, right and

130
00:07:48,920 --> 00:07:50,680
Speaker 1: you know, of course you have to have the technology

131
00:07:50,720 --> 00:07:53,360
Speaker 1: to jump ship, and maybe Old Earth has that, maybe

132
00:07:53,400 --> 00:07:55,200
Speaker 1: it's not even the same place anymore. Well they got

133
00:07:55,280 --> 00:07:58,600
Speaker 1: us here. Yeah, then, and here's the thing. We estimated

134
00:07:58,640 --> 00:08:02,520
Speaker 1: the distance to this nebula by observing the measurements of

135
00:08:02,560 --> 00:08:05,880
Speaker 1: about forty different objects within it. So there's that central star,

136
00:08:05,960 --> 00:08:08,600
Speaker 1: but there's obviously other objects that are moving around. Uh.

137
00:08:08,680 --> 00:08:11,440
Speaker 1: And these have to be objects that have favorable properties

138
00:08:11,720 --> 00:08:14,320
Speaker 1: that we could have seen from Earth. Uh. It's it's

139
00:08:14,320 --> 00:08:17,080
Speaker 1: really difficult actually to see these things from Earth because

140
00:08:17,120 --> 00:08:19,880
Speaker 1: they're all a variety of different shapes and masses, and

141
00:08:19,880 --> 00:08:23,840
Speaker 1: they're all swirling around within this ionized gas. So they're

142
00:08:23,880 --> 00:08:27,560
Speaker 1: not homogeneous. Uh. And when I say they're not homogeneous,

143
00:08:27,600 --> 00:08:29,920
Speaker 1: I'm not just referring to the forty objects within the nebula,

144
00:08:30,160 --> 00:08:33,800
Speaker 1: referring to all planetary nebula. They're all completely different. Uh.

145
00:08:33,800 --> 00:08:36,240
Speaker 1: And that alone is kind of fascinating. So, yeah, we

146
00:08:36,320 --> 00:08:39,200
Speaker 1: learned from them, but what happens with our son when

147
00:08:39,240 --> 00:08:42,040
Speaker 1: it dies is going to be different. So okay, So

148
00:08:42,120 --> 00:08:44,360
Speaker 1: once we figured out the distance, you know, we did

149
00:08:44,360 --> 00:08:47,000
Speaker 1: all this math before we left Earth. We figured out

150
00:08:47,000 --> 00:08:50,000
Speaker 1: the distance from our calculations. Then we found the size

151
00:08:50,040 --> 00:08:53,280
Speaker 1: of the nebula and we also figured out its age

152
00:08:53,440 --> 00:08:57,800
Speaker 1: by dividing the speed of its expansion. Since the central

153
00:08:57,880 --> 00:09:01,880
Speaker 1: stars started objecting layers off. So as the star gets hotter,

154
00:09:02,000 --> 00:09:04,800
Speaker 1: it sheds off layers of elements, and this is what

155
00:09:04,880 --> 00:09:08,479
Speaker 1: forms the colorful clouds of gas, uh that they're surrounded

156
00:09:08,480 --> 00:09:11,360
Speaker 1: by for tens of thousands of years. That's also the

157
00:09:11,400 --> 00:09:15,360
Speaker 1: reason why it's glow is ultraviolet radiation produced by the

158
00:09:15,400 --> 00:09:19,800
Speaker 1: stars heat. It's constantly getting hotter and smaller. There between

159
00:09:20,400 --> 00:09:23,880
Speaker 1: five thousand and two hundred thousand kelvins and that's essentially

160
00:09:23,960 --> 00:09:29,760
Speaker 1: what thousand, five hundred degrees fahrenheit to fifty nine thousand,

161
00:09:29,840 --> 00:09:32,720
Speaker 1: five hundred degrees fair enough, So we've got a cozy

162
00:09:32,760 --> 00:09:35,720
Speaker 1: ship that's well protected here from all the heat. Right,

163
00:09:35,760 --> 00:09:39,160
Speaker 1: otherwise we would be not even like marshmallows. We must

164
00:09:39,200 --> 00:09:44,200
Speaker 1: be be utterly incinerated. Uh. Yeah, it's maximum output is

165
00:09:45,160 --> 00:09:48,440
Speaker 1: ten thousand times as luminous as our sun. So this

166
00:09:48,520 --> 00:09:51,760
Speaker 1: is really what happens to two stars of this type.

167
00:09:52,120 --> 00:09:55,680
Speaker 1: They generate an intense amount of heat due to gravity.

168
00:09:55,960 --> 00:09:58,240
Speaker 1: They get smaller and smaller as they shed off their

169
00:09:58,280 --> 00:10:01,240
Speaker 1: gash and just create a ton of heat and then

170
00:10:01,240 --> 00:10:05,240
Speaker 1: eventually kind of you know, fade away. Oh I hope

171
00:10:05,280 --> 00:10:08,600
Speaker 1: the ship can hold up to this heat. Uh, we'll

172
00:10:08,640 --> 00:10:11,520
Speaker 1: have to look into that after after we've finished chatting. Well,

173
00:10:11,960 --> 00:10:14,240
Speaker 1: you know, let's see. So based on the math, we

174
00:10:14,360 --> 00:10:17,400
Speaker 1: estimate that these nebula are losing up to one percent

175
00:10:17,480 --> 00:10:21,600
Speaker 1: of Earth's mass per day in gases. So I don't

176
00:10:21,600 --> 00:10:23,320
Speaker 1: have the numbers in front of me. Here is how

177
00:10:23,400 --> 00:10:25,360
Speaker 1: large it was when we left, But you know, it's

178
00:10:25,400 --> 00:10:28,200
Speaker 1: been almost two thousand years, as we said, so a

179
00:10:28,240 --> 00:10:30,600
Speaker 1: good amount of that is just floating around out here

180
00:10:30,679 --> 00:10:33,280
Speaker 1: as gas now instead of just like you know, super

181
00:10:33,400 --> 00:10:37,640
Speaker 1: hot mass. Uh. And once it peaks, it eventually cools down.

182
00:10:37,840 --> 00:10:40,320
Speaker 1: Maybe that's where we're at now. It takes ten thousand

183
00:10:40,440 --> 00:10:43,080
Speaker 1: more years for that to happen, though, and then it

184
00:10:43,120 --> 00:10:47,120
Speaker 1: eventually becomes that white dwarf star and it's barely larger

185
00:10:47,160 --> 00:10:49,840
Speaker 1: than the Earth when it's at that size. Uh. And

186
00:10:49,920 --> 00:10:53,679
Speaker 1: these white dwarves they're super dense. Uh, so dense that

187
00:10:53,880 --> 00:10:59,560
Speaker 1: thousands of kilograms are are fit into per cubic centimeters.

188
00:10:59,600 --> 00:11:02,760
Speaker 1: That's a that's intense. So not only do we have

189
00:11:02,960 --> 00:11:06,520
Speaker 1: a ship that's really you know, well built for handling heat,

190
00:11:06,559 --> 00:11:09,400
Speaker 1: but it's also taking on the pressure of all that density,

191
00:11:09,880 --> 00:11:12,480
Speaker 1: you know. Um. I'm also reminded that white dwarves are

192
00:11:12,480 --> 00:11:18,439
Speaker 1: also known as degenerate dwarves. Well, that sounds offensive. Are

193
00:11:18,480 --> 00:11:22,599
Speaker 1: they gully dwarves? Gully from d and d Oh? I

194
00:11:22,600 --> 00:11:25,559
Speaker 1: don't remember. You remember gully dwarves and Dutton dungeons and dragons.

195
00:11:25,559 --> 00:11:27,800
Speaker 1: I wonder if they still have dungeons dragons on Earth.

196
00:11:27,960 --> 00:11:31,760
Speaker 1: Gully dwarves were like these, they were they were dwarves

197
00:11:31,800 --> 00:11:36,240
Speaker 1: that lived in the streets of dragon Lance. I never

198
00:11:36,320 --> 00:11:40,640
Speaker 1: encountered the gully dwarves ever near with the Great Dwarfs. Yeah,

199
00:11:40,640 --> 00:11:44,400
Speaker 1: they're related. Drgar live underground gully dwarves were like, uh,

200
00:11:44,960 --> 00:11:49,080
Speaker 1: they're basically like like homeless dwarves now, not to be

201
00:11:49,080 --> 00:11:52,920
Speaker 1: confused with the darrow, who are kind of homeless dwarves. Yeah,

202
00:11:52,920 --> 00:11:55,600
Speaker 1: I believe they're different. Yeah, there's there's a lot of

203
00:11:55,600 --> 00:11:59,840
Speaker 1: subspecies of dwarves, not including the White Dwarf, which is

204
00:11:59,840 --> 00:12:03,120
Speaker 1: a son and not a fantasy creature, right though White

205
00:12:03,200 --> 00:12:07,480
Speaker 1: Dwarf is a fantasy publication or was uh you know

206
00:12:07,559 --> 00:12:12,520
Speaker 1: two thousand years ago about desktop a tabletop role playing games.

207
00:12:12,559 --> 00:12:16,960
Speaker 1: So many connections. Yeah, maybe that's really what our purpose

208
00:12:17,000 --> 00:12:20,719
Speaker 1: here is to bring this information about dwarves and uh

209
00:12:20,720 --> 00:12:23,400
Speaker 1: and fantasy games into the distant future. Well, like we've

210
00:12:23,440 --> 00:12:25,000
Speaker 1: been saying, I guess it's too late for it now.

211
00:12:25,040 --> 00:12:27,080
Speaker 1: We've always been talking about doing a how stuff works

212
00:12:27,160 --> 00:12:31,000
Speaker 1: Dungeons and Dragons table match, where we just record the

213
00:12:31,000 --> 00:12:33,240
Speaker 1: whole experience, like a mash up of all the hosts

214
00:12:33,240 --> 00:12:35,840
Speaker 1: from shows. Well, if I find everybody else is probably

215
00:12:35,880 --> 00:12:38,559
Speaker 1: dead Joe. Well yeah, if we can find Joe, maybe

216
00:12:38,559 --> 00:12:41,720
Speaker 1: he's around the ship here somewhere hopefully, so you know

217
00:12:41,760 --> 00:12:44,160
Speaker 1: what might have gotten him is the ultra violet radiation though,

218
00:12:44,440 --> 00:12:47,760
Speaker 1: because that is also pouring off of these stars, uh,

219
00:12:47,800 --> 00:12:50,959
Speaker 1: and they're super hot, they're emanating ultra violet radiation. So

220
00:12:51,040 --> 00:12:54,240
Speaker 1: the center of the nebula causes atoms in the outward

221
00:12:54,280 --> 00:12:57,880
Speaker 1: moving gas to lose their electrons, and this is what

222
00:12:58,000 --> 00:13:00,520
Speaker 1: creates the ionized gas. This is what makes it so

223
00:13:00,600 --> 00:13:04,520
Speaker 1: difficult to see from Earth. Originally, you know why they

224
00:13:04,559 --> 00:13:07,120
Speaker 1: call them planetary nebula. I mean they might even call

225
00:13:07,200 --> 00:13:11,000
Speaker 1: them something different now, but it was because earliest stronomers

226
00:13:11,080 --> 00:13:13,800
Speaker 1: they didn't have like great telescopes, so they saw them

227
00:13:13,840 --> 00:13:16,720
Speaker 1: as just like round balls in space and they were like, oh,

228
00:13:16,720 --> 00:13:19,960
Speaker 1: it looks kind of like Uranus and Neptune in the telescope.

229
00:13:20,040 --> 00:13:23,720
Speaker 1: So yeah, planetary nebula. There you go. And uh, you know,

230
00:13:23,880 --> 00:13:25,600
Speaker 1: at least when we left her, if they were still

231
00:13:25,600 --> 00:13:27,440
Speaker 1: calling them that, I don't know, i'd call it like

232
00:13:27,480 --> 00:13:30,079
Speaker 1: a stellar nebula or something like that, right, Yeah, I

233
00:13:30,080 --> 00:13:32,640
Speaker 1: don't know. Of course, when we also left Earth, uranus

234
00:13:32,840 --> 00:13:35,520
Speaker 1: was still a funny word. I don't know if my

235
00:13:35,720 --> 00:13:38,200
Speaker 1: modern listeners out there will even find the humor in

236
00:13:38,200 --> 00:13:41,760
Speaker 1: the dully dwarf nebula. Yeah, that's what I would call it. So,

237
00:13:41,760 --> 00:13:43,840
Speaker 1: a galaxy like the Milky Way is estimated to have

238
00:13:43,920 --> 00:13:47,840
Speaker 1: several thousand planetary nebula at any one time, and we

239
00:13:47,880 --> 00:13:51,439
Speaker 1: think they're about twenty thousand objects that we call planetary

240
00:13:51,480 --> 00:13:54,120
Speaker 1: nebula and the Milky Way, but because of the dust

241
00:13:54,160 --> 00:13:56,960
Speaker 1: around the galaxy, that makes them difficult to observe. So

242
00:13:57,000 --> 00:14:00,200
Speaker 1: we've only cataloged about eighteen. Wow, So that's crazy. Think

243
00:14:00,200 --> 00:14:03,760
Speaker 1: about like, we are in a huge system of a

244
00:14:03,760 --> 00:14:06,840
Speaker 1: planetary nebula, but it is only one of twenty thousand.

245
00:14:06,880 --> 00:14:12,160
Speaker 1: That's just in the Milky Way galaxy. Wow. Life always

246
00:14:12,200 --> 00:14:14,920
Speaker 1: finds a way. Like I was saying, I mean, this

247
00:14:14,960 --> 00:14:18,160
Speaker 1: provides us with a great opportunity to analyze a star

248
00:14:18,320 --> 00:14:20,440
Speaker 1: that was once like our son. Right, we can study

249
00:14:20,480 --> 00:14:23,760
Speaker 1: their chemical composition. We can understand how a star is formed.

250
00:14:24,000 --> 00:14:26,440
Speaker 1: We look at elements like carbon and nitrogen, and we

251
00:14:26,520 --> 00:14:29,920
Speaker 1: figure out the processes like nuclear fusion that are happening

252
00:14:29,960 --> 00:14:33,840
Speaker 1: within the star's lifetime. And maybe, maybe, just maybe we

253
00:14:33,880 --> 00:14:37,120
Speaker 1: will learn more about how our son will change and

254
00:14:37,200 --> 00:14:41,440
Speaker 1: evolve and eventually envelop us in colorful gases. Yeah. I

255
00:14:41,440 --> 00:14:44,040
Speaker 1: mean that's assuming if you and I get back. Yeah,

256
00:14:44,320 --> 00:14:46,360
Speaker 1: we're gonna have to really figure out how to pilot

257
00:14:46,440 --> 00:14:49,640
Speaker 1: this thing now because it's been on Autophile. Well, and

258
00:14:49,720 --> 00:14:51,000
Speaker 1: you know, once we go out there, we'll have to

259
00:14:51,000 --> 00:14:53,080
Speaker 1: decide what we're gonna do about Joe. Like if we're

260
00:14:53,080 --> 00:14:55,280
Speaker 1: gonna bother, look at how long we're gonna bother looking

261
00:14:55,280 --> 00:14:57,200
Speaker 1: for him? Well, yeah, we I mean, you never leave

262
00:14:57,240 --> 00:15:00,000
Speaker 1: a man behind. But I don't know what might have happened.

263
00:15:00,080 --> 00:15:03,440
Speaker 1: Maybe he merged with Carney and they're one cybernetic organism. Now,

264
00:15:03,480 --> 00:15:05,760
Speaker 1: maybe he stepped out through the airlock. Maybe he died

265
00:15:05,760 --> 00:15:07,720
Speaker 1: of old age, Will clicked all of his nails and

266
00:15:07,760 --> 00:15:10,440
Speaker 1: shaved his hair and then just walked right out the airlock.

267
00:15:10,760 --> 00:15:12,840
Speaker 1: Maybe we're supposed to clone him. Maybe that's why he left.

268
00:15:13,120 --> 00:15:17,040
Speaker 1: He's like, please reclone me. If there's cloning services available

269
00:15:17,040 --> 00:15:18,800
Speaker 1: on board here, I'm happy to do that and then

270
00:15:18,800 --> 00:15:22,720
Speaker 1: we can just fly back home. Okay, So where are we?

271
00:15:22,800 --> 00:15:25,960
Speaker 1: Where is the Medusa, Nebula? This thing? I mean, I

272
00:15:26,000 --> 00:15:28,760
Speaker 1: know I said at the top. We flew fifteen hundred

273
00:15:28,920 --> 00:15:31,960
Speaker 1: light years away from Earth. We're in the direction of

274
00:15:32,080 --> 00:15:35,680
Speaker 1: the Gemini constellation right in terms from Earth. So if

275
00:15:35,720 --> 00:15:39,680
Speaker 1: you're on Earth, you stand up you're outside at night

276
00:15:39,800 --> 00:15:43,880
Speaker 1: and you look up, you locate a Ryan. That's another constellation. Uh.

277
00:15:44,040 --> 00:15:46,920
Speaker 1: Gemini is to the northeast of that, and it's between

278
00:15:47,040 --> 00:15:52,440
Speaker 1: Taurus and Cancer. Uh. And it's best observed during February

279
00:15:52,520 --> 00:15:55,560
Speaker 1: on Earth. In that month, you can look straight up

280
00:15:55,600 --> 00:15:59,600
Speaker 1: around ten thirty PM and uh, the whole Gemini constellation

281
00:15:59,640 --> 00:16:01,920
Speaker 1: should be directly overhead, so you'd be looking at us.

282
00:16:01,920 --> 00:16:05,760
Speaker 1: If you can hear this, you'd be looking at us. Yes,

283
00:16:06,160 --> 00:16:08,040
Speaker 1: I'm not sure if you'll see us. And then of

284
00:16:08,040 --> 00:16:12,000
Speaker 1: course you have to account for the for the light. Yeah.

285
00:16:13,600 --> 00:16:16,680
Speaker 1: Well yeah, actually you might be looking at something that

286
00:16:16,720 --> 00:16:18,640
Speaker 1: happened way before we even got here. Yeah, we're gonna

287
00:16:18,640 --> 00:16:20,560
Speaker 1: wave anyway. When we get up to the viewing, a

288
00:16:20,640 --> 00:16:23,320
Speaker 1: deck will wave, and maybe the telescopes are powerful enough

289
00:16:23,360 --> 00:16:25,680
Speaker 1: for you to see us. You'll definitely be able to

290
00:16:25,720 --> 00:16:29,040
Speaker 1: find two stars that make up Gemini. These are twins

291
00:16:29,240 --> 00:16:33,280
Speaker 1: POLLOCKX and Castor. Uh. Fun fact, Robert on Earth. Do

292
00:16:33,360 --> 00:16:36,400
Speaker 1: you remember that expression by Jiminy that so many people

293
00:16:36,560 --> 00:16:39,360
Speaker 1: used by Jiminy, I think I do. It's actually a

294
00:16:39,360 --> 00:16:44,200
Speaker 1: corrupted version of by Gemini, which was used as an exclamation.

295
00:16:44,200 --> 00:16:46,240
Speaker 1: Now that we're here, I think we should bring that back,

296
00:16:46,280 --> 00:16:50,440
Speaker 1: Like where's Joe by Jimini. All that's left here are

297
00:16:50,600 --> 00:16:53,520
Speaker 1: his hair and fingernails. Yeah, let's bring it back. I mean,

298
00:16:54,280 --> 00:16:56,800
Speaker 1: we're we're in out here. We're in a new civilization

299
00:16:56,880 --> 00:16:59,640
Speaker 1: of humanity, so we can just make up all the rules.

300
00:16:59,640 --> 00:17:02,400
Speaker 1: And the only reason we know any of this stuff

301
00:17:02,440 --> 00:17:05,000
Speaker 1: about the Medusa Nebula, or at least what it looked like,

302
00:17:05,440 --> 00:17:07,439
Speaker 1: was because of a program that was going on on

303
00:17:07,520 --> 00:17:11,159
Speaker 1: Earth that was the European Space Organization. They had it

304
00:17:11,240 --> 00:17:14,399
Speaker 1: called the e s O Cosmic Gems Program. It sounds

305
00:17:14,440 --> 00:17:17,240
Speaker 1: like a fun cartoon show or something like that, but

306
00:17:17,280 --> 00:17:21,040
Speaker 1: it's actually an outreach initiative to share the E s

307
00:17:21,040 --> 00:17:23,560
Speaker 1: O S telescope findings. So the e s OS based

308
00:17:23,560 --> 00:17:26,800
Speaker 1: out of Europe. It's supported by sixteen different countries, not

309
00:17:26,880 --> 00:17:31,000
Speaker 1: including the USA, UH and Chili. The country of Chile

310
00:17:31,480 --> 00:17:36,359
Speaker 1: hosts UH their telescopic observatories. There's three there and they're

311
00:17:36,359 --> 00:17:39,600
Speaker 1: currently working or I guess not now it must be built,

312
00:17:39,960 --> 00:17:43,000
Speaker 1: but they were working on the European This is a

313
00:17:43,000 --> 00:17:47,040
Speaker 1: great name for a telescope, the European extremely Large Telescope,

314
00:17:47,760 --> 00:17:50,280
Speaker 1: which they gave the acronym e DASH E l t

315
00:17:51,040 --> 00:17:53,679
Speaker 1: uh and it was thirty nine meters uh and I

316
00:17:53,720 --> 00:17:56,919
Speaker 1: believe in diameter. And it was purportedly going to be

317
00:17:56,960 --> 00:18:00,760
Speaker 1: the world's biggest eye on the sky. So that's important, right,

318
00:18:00,840 --> 00:18:02,840
Speaker 1: because it was on the sky, it wasn't in the sky.

319
00:18:02,920 --> 00:18:06,280
Speaker 1: I believe that James Webb telescope being produced by NASA

320
00:18:06,680 --> 00:18:08,440
Speaker 1: was going to be larger than that. So the main

321
00:18:08,480 --> 00:18:11,159
Speaker 1: mission here was created in in a nineteen sixty two

322
00:18:11,200 --> 00:18:13,760
Speaker 1: convention to provide state of the art research facilities for

323
00:18:13,800 --> 00:18:17,640
Speaker 1: astromoterers and astrophysicists. And they have an annual contribution budget

324
00:18:17,960 --> 00:18:21,320
Speaker 1: from their countries of a hundred and forty million euros.

325
00:18:21,880 --> 00:18:25,520
Speaker 1: The headquarters themselves are near Munich in German name, but

326
00:18:25,520 --> 00:18:29,800
Speaker 1: the telescopes are in Chile. So what's so special about

327
00:18:29,800 --> 00:18:31,960
Speaker 1: the Medusa nebula? Like, why did we bother to come

328
00:18:32,000 --> 00:18:35,120
Speaker 1: here and not to the other you know twenty thousand

329
00:18:35,240 --> 00:18:37,600
Speaker 1: some odd nebula that are out there. Well, I mean

330
00:18:37,600 --> 00:18:41,760
Speaker 1: it looks like Medusa sort of, that's right. We like monsters. Okay,

331
00:18:41,800 --> 00:18:44,640
Speaker 1: that's a good reason. Um, yeah, I hope we had

332
00:18:44,680 --> 00:18:48,000
Speaker 1: some better reasons for them for that. Maybe we've we've

333
00:18:48,000 --> 00:18:51,040
Speaker 1: forgotten something important. Maybe we you know, we brought a

334
00:18:51,040 --> 00:18:54,280
Speaker 1: convenience to our something. Let me look at my notes here. Um.

335
00:18:54,320 --> 00:18:58,960
Speaker 1: It says here that the more generic name for this

336
00:18:59,119 --> 00:19:03,439
Speaker 1: was Abbowl twenty one because it was discovered by an

337
00:19:03,440 --> 00:19:10,240
Speaker 1: American astronomer named George O. Abol in nineteen And they

338
00:19:10,240 --> 00:19:13,520
Speaker 1: actually didn't even realize that it was a planetary nebula

339
00:19:13,600 --> 00:19:16,240
Speaker 1: until the seventies because when they were looking at they thought, oh,

340
00:19:16,240 --> 00:19:20,320
Speaker 1: this must be the remnants of a supernova nova explosion. Um,

341
00:19:20,359 --> 00:19:23,080
Speaker 1: because it had all the properties of the cloud. Then

342
00:19:23,119 --> 00:19:26,600
Speaker 1: they figured out, oh, that's a nebulah. And so astronomers

343
00:19:26,640 --> 00:19:29,119
Speaker 1: today what they do, well, I guess it's not today,

344
00:19:29,280 --> 00:19:34,600
Speaker 1: it would have been two thousands ago. Astronomers apply various

345
00:19:34,640 --> 00:19:38,320
Speaker 1: filters to telescopes so they can isolate the radiation from

346
00:19:38,320 --> 00:19:42,600
Speaker 1: the gases that they see. Because the nebula is specifically

347
00:19:42,600 --> 00:19:45,080
Speaker 1: the Medusa nebula, is actually quite dim in comparison to

348
00:19:45,119 --> 00:19:47,359
Speaker 1: other nebula. Yeah. I think that's one of the reasons

349
00:19:47,440 --> 00:19:49,159
Speaker 1: we decided to go to it, because it's it's not

350
00:19:49,240 --> 00:19:53,639
Speaker 1: as bright, it's a little more. It's probably cooler about it. Uh.

351
00:19:53,720 --> 00:19:57,280
Speaker 1: It is only four light years across, only only only

352
00:19:57,320 --> 00:20:01,360
Speaker 1: four light years across. So think about that. I mean, like, uh,

353
00:20:01,400 --> 00:20:05,359
Speaker 1: the gas expands to quite a huge distance compared to

354
00:20:05,440 --> 00:20:07,920
Speaker 1: actually the size of the star itself. Yeah, it's it's

355
00:20:08,040 --> 00:20:10,600
Speaker 1: as far as human perceptions of these things, it's a

356
00:20:10,600 --> 00:20:12,520
Speaker 1: fairly large region of space, I mean. And then of

357
00:20:12,520 --> 00:20:14,680
Speaker 1: course as far as space goes, it's not big at all.

358
00:20:15,200 --> 00:20:17,600
Speaker 1: And an important thing like if if you're back on

359
00:20:17,640 --> 00:20:19,879
Speaker 1: Earth made you probably have better pictures by now. But

360
00:20:20,240 --> 00:20:23,200
Speaker 1: those photos and you know, I'm assuming if this goes

361
00:20:23,280 --> 00:20:25,680
Speaker 1: up as a podcast and we still use thumbnail images

362
00:20:25,760 --> 00:20:27,679
Speaker 1: like we used to, will use this image of the

363
00:20:27,680 --> 00:20:31,080
Speaker 1: Medusa Nebula from the E s O. But if you're

364
00:20:31,080 --> 00:20:33,720
Speaker 1: looking at that image, you think, oh, the star in

365
00:20:33,760 --> 00:20:36,280
Speaker 1: the center, the one that's glowing the brightest, that's got

366
00:20:36,280 --> 00:20:38,840
Speaker 1: to be the stellar core that's giving off all these gases.

367
00:20:39,119 --> 00:20:41,920
Speaker 1: It's actually not. It's actually dimmer. It's a blue star

368
00:20:42,400 --> 00:20:46,199
Speaker 1: that's just off center of this crescent gas shape. Uh.

369
00:20:46,280 --> 00:20:48,360
Speaker 1: And in the right hand part of the image there's

370
00:20:48,400 --> 00:20:52,480
Speaker 1: a dimmer blue star that's just off center of the

371
00:20:52,520 --> 00:20:55,480
Speaker 1: crescent shape. And that is it. That's the one that's

372
00:20:55,520 --> 00:20:58,800
Speaker 1: giving off all the gas. Uh. And this is my

373
00:20:58,880 --> 00:21:04,000
Speaker 1: favorite part. The double ionized oxygen part So the reason

374
00:21:04,080 --> 00:21:07,920
Speaker 1: why this one in particular has these weird greens, which

375
00:21:07,960 --> 00:21:12,640
Speaker 1: is why I imagined Medusa came into play serpentine green snakes,

376
00:21:13,440 --> 00:21:17,280
Speaker 1: it's because the radiation combines with the gas. Uh. And

377
00:21:17,520 --> 00:21:20,360
Speaker 1: actually scientists thought they'd found a new element. They called

378
00:21:20,400 --> 00:21:23,959
Speaker 1: it nebulum nebulium. I think what we're learning from this

379
00:21:24,080 --> 00:21:27,800
Speaker 1: is that astronomers in the late twentieth century weren't that

380
00:21:27,920 --> 00:21:30,719
Speaker 1: creative when it came to coming up with names dream things.

381
00:21:31,680 --> 00:21:36,680
Speaker 1: But it's symbolized double oxygen. Double ionized oxygen is symbolized

382
00:21:36,720 --> 00:21:40,679
Speaker 1: by within brackets the letter oh followed by three Roman

383
00:21:40,840 --> 00:21:45,679
Speaker 1: numeral ones, so it's it looks kind of like oh

384
00:21:45,800 --> 00:21:49,520
Speaker 1: one one one or something like that, yeah, oh three

385
00:21:49,840 --> 00:21:55,240
Speaker 1: oh three yeah, uh, and it's uh. That's how we're

386
00:21:55,280 --> 00:21:58,240
Speaker 1: basically able to spot this so easily. Like I said,

387
00:21:58,280 --> 00:22:01,800
Speaker 1: it's fairly dim nebula. The greens were really standing out,

388
00:22:02,080 --> 00:22:06,320
Speaker 1: so they basically realized, okay, this is a radiation wavelength

389
00:22:06,359 --> 00:22:08,760
Speaker 1: that's not a new element. They put those filters on

390
00:22:08,840 --> 00:22:10,919
Speaker 1: and then they could see it much better. And indeed,

391
00:22:10,920 --> 00:22:13,160
Speaker 1: I look forward to looking at it through our special

392
00:22:13,160 --> 00:22:16,160
Speaker 1: goggles that will allow us to to see these, uh,

393
00:22:16,200 --> 00:22:19,000
Speaker 1: these details from these here on site when we're just

394
00:22:19,080 --> 00:22:24,840
Speaker 1: surrounded by a four light year across entity that's everywhere.

395
00:22:24,880 --> 00:22:27,439
Speaker 1: Really it's kind of hard to see the colors. But

396
00:22:27,520 --> 00:22:31,240
Speaker 1: we've we brought these these great goggles. Yeah, really much

397
00:22:31,280 --> 00:22:33,600
Speaker 1: better than Google Glass turned out to be. Yeah, I

398
00:22:33,640 --> 00:22:35,359
Speaker 1: mean unless it. I mean it had to two thousand

399
00:22:35,440 --> 00:22:38,119
Speaker 1: additional years to get awesome. So maybe a Google glass

400
00:22:38,160 --> 00:22:41,160
Speaker 1: two thousand. You know. We mentioned earlier that the nebula

401
00:22:41,280 --> 00:22:45,159
Speaker 1: that we now inhapned was discovered by American astronomer George O. A.

402
00:22:45,280 --> 00:22:48,879
Speaker 1: Bell In. I was actually researching him a little bit.

403
00:22:49,160 --> 00:22:52,080
Speaker 1: He was a noted skeptic in the day and involved

404
00:22:52,080 --> 00:22:56,520
Speaker 1: in that skeptic interest, you know, taking taking down magicians

405
00:22:56,600 --> 00:23:01,040
Speaker 1: and uh and and fraudulent you know, hypnotists and the like.

406
00:23:01,280 --> 00:23:03,200
Speaker 1: Oh well, maybe he would have been a fan of

407
00:23:03,200 --> 00:23:06,000
Speaker 1: our sister show stuff they don't want you to know

408
00:23:06,760 --> 00:23:09,520
Speaker 1: where they you know, explore that that type of stuff. Yeah,

409
00:23:10,280 --> 00:23:15,080
Speaker 1: him trails. I bet he'd be really big on chem trails. Um. Okay,

410
00:23:15,480 --> 00:23:19,040
Speaker 1: so this thing's expanding pretty quickly, so we need to

411
00:23:19,040 --> 00:23:20,840
Speaker 1: get our work done and then get out of here.

412
00:23:21,760 --> 00:23:25,120
Speaker 1: The Medusa nebula, we knew this before we even got here,

413
00:23:25,160 --> 00:23:28,000
Speaker 1: because of all the measurements that I mentioned earlier. It

414
00:23:28,040 --> 00:23:31,679
Speaker 1: expands at a rate of fifty kilometers a second, so

415
00:23:31,720 --> 00:23:35,360
Speaker 1: that gas is just constantly pouring out of that central

416
00:23:35,480 --> 00:23:39,199
Speaker 1: stellar area. Uh. And it's much lower than is actually

417
00:23:39,240 --> 00:23:42,920
Speaker 1: expected for most supernova remnants. Uh. Well, well, what they

418
00:23:42,960 --> 00:23:45,720
Speaker 1: thought was a supernova remnant. Uh, And it's how they

419
00:23:45,800 --> 00:23:47,760
Speaker 1: figured out that it was a nebula. In fact, a

420
00:23:47,800 --> 00:23:53,640
Speaker 1: typical planetary nebula expands somewhere between twenty four fifty six

421
00:23:53,720 --> 00:23:57,159
Speaker 1: kilometers a second, so around an average of thirty kilometers

422
00:23:57,200 --> 00:24:00,159
Speaker 1: per second. That's that's nuts to me, especially when you

423
00:24:00,600 --> 00:24:05,040
Speaker 1: compare that that this huge system right that's floating around

424
00:24:05,040 --> 00:24:07,520
Speaker 1: out in space. And then we go back to what

425
00:24:07,560 --> 00:24:11,200
Speaker 1: we talked about earlier this week. The osadax worm down

426
00:24:11,200 --> 00:24:14,960
Speaker 1: to one centimeter and they're they're both kind of beautiful

427
00:24:15,000 --> 00:24:17,720
Speaker 1: in their own way depending on the scale, also kind

428
00:24:17,720 --> 00:24:21,040
Speaker 1: of terrifying and monstrous, uh, depending on the scale at

429
00:24:21,080 --> 00:24:23,000
Speaker 1: what you're looking at them at. Yeah. Indeed, and also

430
00:24:23,080 --> 00:24:25,760
Speaker 1: ephemeral depending on when you're looking at them, whether you're

431
00:24:25,760 --> 00:24:30,040
Speaker 1: looking at the life cycle of a planetary nebula versus

432
00:24:30,080 --> 00:24:32,440
Speaker 1: the life cycle of of a whale fall. Who knows,

433
00:24:32,520 --> 00:24:36,840
Speaker 1: maybe maybe like an osadax worm, the Medusa nebula has

434
00:24:37,000 --> 00:24:41,439
Speaker 1: tiny little male versions of itself, hundreds of them inside it.

435
00:24:41,520 --> 00:24:45,120
Speaker 1: Those might be coming to devour us right now. One

436
00:24:45,119 --> 00:24:47,720
Speaker 1: can only wonder. Hey, let's go ahead and put these

437
00:24:47,720 --> 00:24:50,120
Speaker 1: goggles on and head upstairs. Now we're not gonna we're

438
00:24:50,240 --> 00:24:52,480
Speaker 1: I think we're gonna run out of out of time

439
00:24:52,720 --> 00:24:55,240
Speaker 1: to record anymore, so we're not gonna be able to

440
00:24:55,240 --> 00:24:58,160
Speaker 1: really share what we see. I'm sure it's gonna be wonderful. Otherwise,

441
00:24:58,280 --> 00:25:00,840
Speaker 1: this whole trip was kind of a bust. But but

442
00:25:01,000 --> 00:25:03,560
Speaker 1: maybe everyone would like to chime in on what they

443
00:25:03,600 --> 00:25:06,960
Speaker 1: think we'll see. What would you see if you took

444
00:25:07,000 --> 00:25:10,560
Speaker 1: a two thousand year journey out to a planetary nebula

445
00:25:10,760 --> 00:25:14,239
Speaker 1: and attempted to look outward from its center? Yeah, let

446
00:25:14,320 --> 00:25:18,119
Speaker 1: us know. I guess maybe these are still platforms. I

447
00:25:18,119 --> 00:25:22,280
Speaker 1: mean they were popular at the time, Facebook, Twitter, and tumbler.

448
00:25:22,480 --> 00:25:25,680
Speaker 1: Tumblers probably not around anymore. Well, let's hope. Let's hope

449
00:25:25,720 --> 00:25:28,800
Speaker 1: the story maybe the only thing that's around maybe older

450
00:25:29,400 --> 00:25:32,040
Speaker 1: just tumbling. I don't even mean humans anymore, there's only tumbling.

451
00:25:32,119 --> 00:25:34,520
Speaker 1: We'll write us if you can write us on those platforms.

452
00:25:34,560 --> 00:25:36,960
Speaker 1: But I bet, I bet this one's still up there.

453
00:25:37,640 --> 00:25:40,959
Speaker 1: Uh email, that was a thing when we left, right
