1
00:00:01,360 --> 00:00:04,080
Speaker 1: Hey, everybody, this is Chuck bringing you this week's S

2
00:00:04,200 --> 00:00:09,479
Speaker 1: Y s K Select and we are going there. People. Well,

3
00:00:09,840 --> 00:00:11,880
Speaker 1: Josh actually doesn't even know I'm picking this one yet,

4
00:00:11,880 --> 00:00:14,440
Speaker 1: so he might be mad. But what you were about

5
00:00:14,440 --> 00:00:19,560
Speaker 1: to hear is the legendary How the Sun Works episode. Uh.

6
00:00:19,600 --> 00:00:21,280
Speaker 1: And if you haven't heard us talk about this over

7
00:00:21,320 --> 00:00:24,400
Speaker 1: the years, then you haven't listened to many episodes or

8
00:00:24,440 --> 00:00:27,160
Speaker 1: heard many interviews with us, because this one has gone

9
00:00:27,200 --> 00:00:31,840
Speaker 1: down and stuff you should know lore as uh, what

10
00:00:31,880 --> 00:00:35,480
Speaker 1: we call our worst episode ever because it was so

11
00:00:35,600 --> 00:00:38,680
Speaker 1: hard and we were so in over our heads and

12
00:00:38,720 --> 00:00:42,320
Speaker 1: we were clinging to the cliff side by our little

13
00:00:42,440 --> 00:00:46,720
Speaker 1: nubby fingers during the entire podcast and got a lot

14
00:00:46,720 --> 00:00:50,640
Speaker 1: of it wrong. And so, uh, instead of burying this thing,

15
00:00:51,760 --> 00:00:56,000
Speaker 1: I chose to highlight it this week. So, without further ado,

16
00:00:56,160 --> 00:01:04,120
Speaker 1: from January two thousand ten, are amazing episode How the

17
00:01:04,160 --> 00:01:16,959
Speaker 1: Sun Works. Enjoy m Welcome to Stuff you Should Know

18
00:01:17,560 --> 00:01:25,800
Speaker 1: from House Stuff Works dot com. Hey, and welcome to

19
00:01:25,840 --> 00:01:32,440
Speaker 1: the podcast. I am Josh Clark. That's Chuck Bryant. Charles

20
00:01:32,520 --> 00:01:35,640
Speaker 1: Charles W. Bryant is not very happy right now. I'm

21
00:01:35,680 --> 00:01:40,479
Speaker 1: gonna handle this, okay, Chuck the whole thing. This disclaimer. Okay,

22
00:01:41,280 --> 00:01:45,640
Speaker 1: as we prove with our large Hadron Collider podcast, Chuck

23
00:01:45,680 --> 00:01:47,760
Speaker 1: and I are not physicists. By the way, it doesn't

24
00:01:47,760 --> 00:01:52,240
Speaker 1: shoot light. No, we found out speaking of light, we're

25
00:01:52,280 --> 00:01:55,160
Speaker 1: about to talk about sun. Yes, And I just want

26
00:01:55,200 --> 00:01:57,800
Speaker 1: to say that Chuck and I are not astrophysicists either.

27
00:01:58,080 --> 00:02:00,440
Speaker 1: There's a couple of guys who like to drink some

28
00:02:00,560 --> 00:02:03,960
Speaker 1: beer and you know, just talk. Just wrap. I thought

29
00:02:04,000 --> 00:02:06,639
Speaker 1: I was an astrophysicist until I read the Sun article

30
00:02:06,680 --> 00:02:08,720
Speaker 1: and then my brain melted and newsed out of my ears.

31
00:02:08,880 --> 00:02:13,679
Speaker 1: You're an astrophysicist. You're way off, way off. So we're

32
00:02:13,720 --> 00:02:16,040
Speaker 1: going to talk about the sun. If we get any

33
00:02:16,080 --> 00:02:19,160
Speaker 1: of the um you know, theory, if we get the

34
00:02:19,160 --> 00:02:21,960
Speaker 1: theory of relativity, and actually no, we can't screw that

35
00:02:22,000 --> 00:02:24,600
Speaker 1: one up. It's too famous. If there's a little thing

36
00:02:24,680 --> 00:02:26,960
Speaker 1: here there and you're an astrophysicist, please feel free to

37
00:02:27,000 --> 00:02:30,239
Speaker 1: send it's an email correcting us. We love that. Um

38
00:02:30,280 --> 00:02:32,400
Speaker 1: that's the first time we've ever called for corrections before.

39
00:02:34,240 --> 00:02:37,600
Speaker 1: I think this one's appropriate. So let's let's let me start. Chuck,

40
00:02:38,320 --> 00:02:42,440
Speaker 1: have you ever heard of the sun? Yes, Josh, I

41
00:02:42,480 --> 00:02:44,000
Speaker 1: wish we had more of it these days here in

42
00:02:44,200 --> 00:02:47,160
Speaker 1: cold it is, it's a little chilly. If you'll notice

43
00:02:47,200 --> 00:02:50,040
Speaker 1: it's snowed here, Chuck. I feel notice though, after a

44
00:02:50,040 --> 00:02:53,480
Speaker 1: couple of days of sunlight the snow receded. Yes, do

45
00:02:53,520 --> 00:02:59,720
Speaker 1: you know why? Uh? No, radiation Okay, heat, yes, yeah,

46
00:03:00,080 --> 00:03:05,240
Speaker 1: energy from the sun. Right. The Sun, which, Josh, is

47
00:03:05,360 --> 00:03:07,960
Speaker 1: one of over one hundred billion stars. It's just a

48
00:03:08,000 --> 00:03:11,280
Speaker 1: star it is, and not even like a giant star either.

49
00:03:11,400 --> 00:03:15,239
Speaker 1: It falls a little above average size. Did you know that?

50
00:03:15,520 --> 00:03:18,519
Speaker 1: Should we talk about the size? Yeah? Because if there's

51
00:03:18,560 --> 00:03:21,040
Speaker 1: one thing I can do is read stats. Yeah, this was.

52
00:03:21,080 --> 00:03:23,080
Speaker 1: This is a very stat heavy article, so it should

53
00:03:23,080 --> 00:03:26,840
Speaker 1: be up your alley, Josh. The Sun's radius is about

54
00:03:26,880 --> 00:03:29,600
Speaker 1: four hundred and thirty two thousand miles. Yeah, it's a

55
00:03:29,680 --> 00:03:32,959
Speaker 1: hundred nine times the radius of the Earth. Yes, one

56
00:03:32,960 --> 00:03:35,240
Speaker 1: on nine exactly, which I was like, Wow, that means

57
00:03:35,280 --> 00:03:38,720
Speaker 1: that it has a two hundred and eighteen times a diameter.

58
00:03:39,000 --> 00:03:43,040
Speaker 1: No that's not true. Still one on nine. It's constant. Uh,

59
00:03:43,080 --> 00:03:45,960
Speaker 1: And I like this. NASA. NASA broke it down, our

60
00:03:45,960 --> 00:03:49,240
Speaker 1: good friends at NASA into something that I understood, which was,

61
00:03:49,280 --> 00:03:52,360
Speaker 1: if you think of the Earth, um the width of

62
00:03:52,360 --> 00:03:55,000
Speaker 1: an ordinary paper clip is the Earth's radius. Let's say,

63
00:03:55,320 --> 00:03:57,840
Speaker 1: then the Sun's radius would be roughly the height of

64
00:03:57,840 --> 00:04:00,800
Speaker 1: a desk. And I know this one about one hundred

65
00:04:00,840 --> 00:04:03,000
Speaker 1: steps from each other. Is that what you're gonna say

66
00:04:03,040 --> 00:04:06,480
Speaker 1: it was? That's all right? Hey? So yeah, that kind

67
00:04:06,480 --> 00:04:08,280
Speaker 1: of puts it in a perspective. The Sun's a hell

68
00:04:08,320 --> 00:04:10,440
Speaker 1: of a lot bigger than the Earth, much much bigger,

69
00:04:10,480 --> 00:04:13,160
Speaker 1: and it's pretty far away, right, how many miles did

70
00:04:13,160 --> 00:04:17,680
Speaker 1: you say? Eight light minutes? Which is actually, chuck, apparently

71
00:04:17,760 --> 00:04:21,359
Speaker 1: ninety two million miles and change. And to put that

72
00:04:21,360 --> 00:04:25,200
Speaker 1: into perspective, other stars are light years away, not eight

73
00:04:25,320 --> 00:04:28,960
Speaker 1: light minutes away. And since this is a stat bonanza,

74
00:04:29,000 --> 00:04:31,640
Speaker 1: can I take a shot at one? So you said

75
00:04:31,680 --> 00:04:35,280
Speaker 1: that the uh, the Sun was how many light years?

76
00:04:35,279 --> 00:04:38,040
Speaker 1: Twenty five thousand light years from the center of the galaxy. Yes,

77
00:04:38,400 --> 00:04:40,960
Speaker 1: it takes about two hundred and fifty million years for

78
00:04:41,000 --> 00:04:45,600
Speaker 1: the Sun to uh do one revolution around the galaxy?

79
00:04:46,560 --> 00:04:48,760
Speaker 1: Can we stop here? I feel really good about it

80
00:04:48,800 --> 00:04:51,479
Speaker 1: so far. Yeah, I'm feeling pretty good. To check. Let's

81
00:04:51,520 --> 00:04:53,920
Speaker 1: soldier on, shall we Yes, the Sun is a G

82
00:04:54,120 --> 00:04:58,520
Speaker 1: two type star based on its temperature and the wavelengths

83
00:04:58,600 --> 00:05:01,320
Speaker 1: of light that it minutes, right, and it's about four

84
00:05:01,360 --> 00:05:04,320
Speaker 1: and a half billion years old, uh, which makes it

85
00:05:04,360 --> 00:05:07,359
Speaker 1: a population one star. Apparently there are two types of

86
00:05:07,400 --> 00:05:10,159
Speaker 1: stars as far as age classification goes. I didn't know

87
00:05:10,200 --> 00:05:13,159
Speaker 1: that population one star are the younger stars, which include

88
00:05:13,160 --> 00:05:16,720
Speaker 1: our sun. Population two stars are older, and they think

89
00:05:16,760 --> 00:05:19,000
Speaker 1: that there was a third population, but none of them

90
00:05:19,000 --> 00:05:22,040
Speaker 1: are around anymore. Population three. Right, they should just go

91
00:05:22,040 --> 00:05:25,360
Speaker 1: ahead and just claim that why not exactly, We wouldn't know.

92
00:05:25,400 --> 00:05:27,760
Speaker 1: We'd be like, oh, nobody would ever know. Right. Well,

93
00:05:27,839 --> 00:05:31,760
Speaker 1: luckily NASA is very honest and forth right. Thank thank you, NASA,

94
00:05:31,839 --> 00:05:34,760
Speaker 1: Thank you. So yeah, check the Sun we said, is

95
00:05:34,880 --> 00:05:37,320
Speaker 1: about four and a half billion years old um, and

96
00:05:37,400 --> 00:05:41,919
Speaker 1: they think it's about humanity arrived at about the halfway

97
00:05:41,960 --> 00:05:45,000
Speaker 1: point in the Sun's lifetime. It's got about five billion

98
00:05:45,000 --> 00:05:48,880
Speaker 1: more years worth of UM fuel, which is good news,

99
00:05:49,320 --> 00:05:51,159
Speaker 1: it is, because yeah, at the end of that run,

100
00:05:51,200 --> 00:05:53,400
Speaker 1: it's not good news for us. No, we'll get to that.

101
00:05:53,400 --> 00:05:57,000
Speaker 1: That'll be the grand finale. How about that? Exactly? All right? So, Chuck,

102
00:05:57,040 --> 00:05:59,320
Speaker 1: what is the Sun? What should we talk about the

103
00:05:59,320 --> 00:06:02,240
Speaker 1: parts of the Sun or I just want to talk

104
00:06:02,240 --> 00:06:05,400
Speaker 1: about the fact that it's a big you know, ball

105
00:06:05,440 --> 00:06:08,040
Speaker 1: of gas. I think we should mention that because if you,

106
00:06:08,200 --> 00:06:10,800
Speaker 1: if you talk about what the Sun is, I think

107
00:06:10,839 --> 00:06:14,080
Speaker 1: it's easier to understand it's different components and then in

108
00:06:14,200 --> 00:06:17,760
Speaker 1: turn what it is. Okay, well, it's made up entirely

109
00:06:17,800 --> 00:06:21,239
Speaker 1: of gas josh, which is really weird because gas generally

110
00:06:21,279 --> 00:06:24,120
Speaker 1: doesn't form a ball and have an atmosphere and all

111
00:06:24,160 --> 00:06:26,280
Speaker 1: that stuff. I know why though, why because of the

112
00:06:26,360 --> 00:06:32,680
Speaker 1: extreme gravity. Yeah, and heat and heat right holds everything together, right,

113
00:06:32,720 --> 00:06:36,520
Speaker 1: which is crazy. So this extreme this extreme heat actually

114
00:06:36,880 --> 00:06:40,000
Speaker 1: uh takes this gas and converts it into what is

115
00:06:40,040 --> 00:06:43,479
Speaker 1: technically a fourth state of matter. You've got solid liquid

116
00:06:43,480 --> 00:06:46,560
Speaker 1: gas and plasma. Plasma, and plasma is a type of

117
00:06:46,600 --> 00:06:50,160
Speaker 1: gas um that behaves in a way where it's um

118
00:06:50,200 --> 00:06:55,120
Speaker 1: it responds to magnetism. Right. Generally people just say that

119
00:06:55,160 --> 00:06:57,719
Speaker 1: it's gas, but unless you want to get really technical,

120
00:06:57,720 --> 00:07:00,560
Speaker 1: and you'll call it plasma. Yeah, that's what nassas it is. Like.

121
00:07:00,600 --> 00:07:04,279
Speaker 1: Scientists only sometimes will even call it plasma. Right. So,

122
00:07:04,440 --> 00:07:06,960
Speaker 1: the core, which we'll talk about in just a second.

123
00:07:07,160 --> 00:07:09,640
Speaker 1: But the core is so dense thanks to the force

124
00:07:09,680 --> 00:07:13,440
Speaker 1: of gravity that um it makes up two of the

125
00:07:13,480 --> 00:07:16,480
Speaker 1: Sun's volume, but it counts for half of the density

126
00:07:16,520 --> 00:07:20,760
Speaker 1: of the entire Sun. Right, and so the the gravitational

127
00:07:20,840 --> 00:07:25,080
Speaker 1: field in the core is so strong that it pulls

128
00:07:25,680 --> 00:07:30,720
Speaker 1: hydrogen atoms together in a nuclear reaction, a fusion reaction,

129
00:07:31,840 --> 00:07:35,480
Speaker 1: which is where everything begins. Yes, this is what everything

130
00:07:35,520 --> 00:07:37,760
Speaker 1: is accounted for for the Sun, right. Yeah. And a

131
00:07:37,840 --> 00:07:40,800
Speaker 1: fusion reaction, just if you guys don't know, is when

132
00:07:40,800 --> 00:07:44,640
Speaker 1: two atomic nuclei joined together and create a new nucleus.

133
00:07:45,760 --> 00:07:49,640
Speaker 1: And so the key um, the key element, I guess,

134
00:07:50,280 --> 00:07:53,000
Speaker 1: uh in the Sun's nuclear reactions, because that's all it is.

135
00:07:53,080 --> 00:07:55,880
Speaker 1: It's not it's not burning like we consider like a

136
00:07:55,920 --> 00:07:59,760
Speaker 1: wood fire to be burning. It's burning like a It's

137
00:07:59,760 --> 00:08:03,000
Speaker 1: a huge nuclear reaction basic the sunnets right, um. But

138
00:08:03,080 --> 00:08:07,000
Speaker 1: the key element is a helium four. When helium four

139
00:08:07,080 --> 00:08:11,200
Speaker 1: is created, um, the it has actually less mass than

140
00:08:11,240 --> 00:08:15,720
Speaker 1: the two I think hydrogen atoms that originally began that

141
00:08:15,840 --> 00:08:18,000
Speaker 1: set off this chain reaction that led to the creation

142
00:08:18,000 --> 00:08:21,920
Speaker 1: of helium four. And since matter or energy can either

143
00:08:21,960 --> 00:08:24,280
Speaker 1: be created nor destroyed, it has to be displaced. Right.

144
00:08:24,680 --> 00:08:28,080
Speaker 1: So under Einstein's theory relativity, which we won't screw up here,

145
00:08:28,680 --> 00:08:31,800
Speaker 1: energy equals mass times of speed of light squared. You

146
00:08:31,840 --> 00:08:36,760
Speaker 1: can describe how much energy is created. Right, So when

147
00:08:36,760 --> 00:08:41,079
Speaker 1: the mass is displaced, when the helium four atom is created, right,

148
00:08:41,400 --> 00:08:45,840
Speaker 1: the mass is this placed, it's created, it transfers into energy. Right.

149
00:08:46,720 --> 00:08:50,000
Speaker 1: I'm wondering how many of our commuters right now switch

150
00:08:50,080 --> 00:08:53,080
Speaker 1: this off and just put on Howard Stern, Like my

151
00:08:53,200 --> 00:08:58,080
Speaker 1: fingernails are bleeding. I'm hanging on just barely right now, thanks, buddy.

152
00:08:58,120 --> 00:09:29,320
Speaker 1: So are you all right? So Chuck, that's the core,

153
00:09:29,480 --> 00:09:32,440
Speaker 1: that's the center of the sun. Yes, it extends to

154
00:09:33,640 --> 00:09:35,360
Speaker 1: of the Sun's radius, just so you know how big

155
00:09:35,400 --> 00:09:39,840
Speaker 1: that is. And it's hot, hot, hot kelvin, which is

156
00:09:39,880 --> 00:09:44,319
Speaker 1: really hot. Trust u um. And uh, that's at the center,

157
00:09:44,400 --> 00:09:48,040
Speaker 1: like you said, it's the radius. What's outside of that?

158
00:09:48,920 --> 00:09:52,720
Speaker 1: Just outside of that is the radiative zone. Is how

159
00:09:52,720 --> 00:09:56,480
Speaker 1: you pronounce that one? Either that or radiative radiative radiative

160
00:09:57,800 --> 00:10:03,160
Speaker 1: that extends about of the Sun's radius from the core, right, Okay,

161
00:10:03,240 --> 00:10:07,680
Speaker 1: So uh, these helium four atoms are created, and remember

162
00:10:07,720 --> 00:10:12,199
Speaker 1: they create energy or they displace energy. Right when they

163
00:10:12,360 --> 00:10:16,520
Speaker 1: lose their mass translation energy, that energy starts traveling outward

164
00:10:16,880 --> 00:10:19,960
Speaker 1: and it hits the radiative zone, and they are they're

165
00:10:20,040 --> 00:10:23,800
Speaker 1: generally um. The type of energy that's created can be

166
00:10:23,880 --> 00:10:28,000
Speaker 1: gamma rays, X rays, whatever, But technically all of these

167
00:10:28,160 --> 00:10:31,640
Speaker 1: are um light waves. So they're carried in these discrete

168
00:10:31,640 --> 00:10:35,319
Speaker 1: little packets called photons, right, Yes, they're carried by the photons.

169
00:10:35,360 --> 00:10:39,680
Speaker 1: And uh, the photon travels only about one micron, which

170
00:10:39,720 --> 00:10:42,600
Speaker 1: is a millionth of a meter, before it's absorbed by

171
00:10:42,679 --> 00:10:45,680
Speaker 1: a gas molecule. Right. Okay, So then this photon which

172
00:10:45,679 --> 00:10:48,920
Speaker 1: is absorbed by the gas molecule, heats the gas molecule up,

173
00:10:49,400 --> 00:10:52,680
Speaker 1: and then the photon or the gas molecule spits out

174
00:10:52,880 --> 00:10:55,959
Speaker 1: another photon, which is technically the same one because it's

175
00:10:56,000 --> 00:10:58,880
Speaker 1: the same wavelength as the original photon, right, and then

176
00:10:58,920 --> 00:11:03,040
Speaker 1: it shows another micro until it's absorbed by another gas molecule. Right.

177
00:11:03,240 --> 00:11:05,840
Speaker 1: So this keeps going on and on and on, and

178
00:11:06,320 --> 00:11:11,160
Speaker 1: by the time the photon escapes from the radiative zone, uh,

179
00:11:11,400 --> 00:11:14,320
Speaker 1: averages about a million years from the time it was

180
00:11:15,200 --> 00:11:18,400
Speaker 1: I guess created. You could say from the creation of

181
00:11:18,440 --> 00:11:22,240
Speaker 1: that helium four adam a million years for one photon

182
00:11:22,640 --> 00:11:26,160
Speaker 1: of light to travel this uh this short distance. Yeah,

183
00:11:26,200 --> 00:11:28,920
Speaker 1: that would be ten to the twenty five absorption and

184
00:11:28,960 --> 00:11:31,880
Speaker 1: re emissions taking place. Yeah, that's a lot. That's a

185
00:11:31,880 --> 00:11:35,080
Speaker 1: lot of zeroes. Yeah, um, it's actually uh, I think

186
00:11:36,240 --> 00:11:40,960
Speaker 1: exactly maybe twenty six. So once it escapes the radiative zone,

187
00:11:41,240 --> 00:11:44,160
Speaker 1: it hits the convective zone right right, and that is

188
00:11:44,160 --> 00:11:49,600
Speaker 1: the final thirty percent of the Sun's radius basically, right. Uh.

189
00:11:49,679 --> 00:11:52,080
Speaker 1: It takes a little while for that same photon to

190
00:11:52,240 --> 00:11:56,839
Speaker 1: escape that area, right, A hundred thousand to two hundred

191
00:11:56,880 --> 00:11:59,240
Speaker 1: thousand years to reach the surface of the Sun. Yes,

192
00:11:59,400 --> 00:12:02,240
Speaker 1: what's crazy is this. Once it escapes, Once that one

193
00:12:02,280 --> 00:12:05,840
Speaker 1: photon escapes services Sun, it takes eight minutes to reach

194
00:12:05,880 --> 00:12:09,080
Speaker 1: the Earth's surface because remember where it's light minutes away,

195
00:12:09,080 --> 00:12:11,560
Speaker 1: and its light travels at the speed of light, so

196
00:12:11,600 --> 00:12:14,720
Speaker 1: it takes eight minutes. But the sunlight that's hitting us

197
00:12:14,760 --> 00:12:18,120
Speaker 1: when we go outside are made up of photons that

198
00:12:18,160 --> 00:12:21,160
Speaker 1: were created more than one point two million years ago.

199
00:12:21,360 --> 00:12:24,520
Speaker 1: I can't even comprehend that. Awesome. That is really really cool.

200
00:12:24,559 --> 00:12:27,000
Speaker 1: So we've got all these ancient photons bouncing office. But

201
00:12:27,080 --> 00:12:29,880
Speaker 1: let's get back to the convective zone, right, Okay, this

202
00:12:29,960 --> 00:12:32,760
Speaker 1: is uh, this is this area made up of these

203
00:12:33,320 --> 00:12:37,920
Speaker 1: alternating areas of rising and cooling gas. Right as NASA

204
00:12:38,080 --> 00:12:40,640
Speaker 1: once again breaks it down, a little easier. It's boiling

205
00:12:40,679 --> 00:12:43,360
Speaker 1: convection cells basically, right, it looks like a pot of

206
00:12:43,360 --> 00:12:49,120
Speaker 1: boiling water, except these are gas plasma. No, there's only

207
00:12:49,160 --> 00:12:51,400
Speaker 1: the Sun. Only the Sun. Okay, chuck. So we have

208
00:12:51,520 --> 00:12:53,319
Speaker 1: the three parts of the Sun. We have the core,

209
00:12:53,760 --> 00:12:56,920
Speaker 1: the radiative zone, and the convective zone. Right, and now

210
00:12:56,920 --> 00:13:00,000
Speaker 1: we've reached the atmosphere. The Sun actually has an atmosphere.

211
00:13:00,480 --> 00:13:02,480
Speaker 1: Yes it does, Yes, it does. And that's made up

212
00:13:02,480 --> 00:13:06,360
Speaker 1: of three parts as well, right, correct, the photosphere, the chromosphere,

213
00:13:06,720 --> 00:13:09,600
Speaker 1: and my favorite, I think everyone's favorite, the corona. I

214
00:13:09,679 --> 00:13:12,960
Speaker 1: like the corona, which can only be seen in an eclipse. Yeah,

215
00:13:13,000 --> 00:13:15,679
Speaker 1: corona gets all the press, it does, so, Joshua. In

216
00:13:15,720 --> 00:13:18,080
Speaker 1: the photosphere we are is that where we are it

217
00:13:18,200 --> 00:13:20,720
Speaker 1: is hot. That is the lowest region in the atmosphere,

218
00:13:20,760 --> 00:13:25,120
Speaker 1: or Sun's atmosphere, and that is the region that you

219
00:13:25,160 --> 00:13:27,280
Speaker 1: can actually see from Earth. That's where you can start

220
00:13:27,280 --> 00:13:29,840
Speaker 1: to see things. Right. And actually the photosphere is what

221
00:13:30,000 --> 00:13:33,400
Speaker 1: gives the Sun. It's kind of round crisp edge because

222
00:13:33,440 --> 00:13:37,760
Speaker 1: as as um as you travel outward to the outside

223
00:13:37,800 --> 00:13:40,440
Speaker 1: of the photosphere, the gas is cooler, which creates that

224
00:13:40,520 --> 00:13:43,760
Speaker 1: crisp edge we see for the Sun right, has an

225
00:13:43,800 --> 00:13:46,560
Speaker 1: average temp of about fifty eight hundred kelvin, and it

226
00:13:46,720 --> 00:13:52,199
Speaker 1: is two hundred and forty miles wide. Right, that's big.

227
00:13:52,360 --> 00:13:55,640
Speaker 1: It is big. After that is the chromosphere, right, Yes,

228
00:13:55,880 --> 00:14:00,800
Speaker 1: that's outside the photosphere. Obviously, it's about my els above

229
00:14:01,120 --> 00:14:05,280
Speaker 1: the photosphere, right, and that's about degrease kelvin. So obviously

230
00:14:05,320 --> 00:14:07,600
Speaker 1: you'll notice that it's getting cooler, you know, as you

231
00:14:07,640 --> 00:14:10,720
Speaker 1: expand outward, right, but it's still they think it's heated

232
00:14:10,760 --> 00:14:15,800
Speaker 1: by the photosphere and this this churning gas, the convection

233
00:14:15,840 --> 00:14:19,240
Speaker 1: cells are still present in the chromosphere as well. So

234
00:14:19,280 --> 00:14:22,840
Speaker 1: basically the what what we're seeing so far is the

235
00:14:22,880 --> 00:14:26,960
Speaker 1: Sun is this nuclear reactor that at its core, gravity

236
00:14:27,000 --> 00:14:32,000
Speaker 1: is pushing things together and then they're exploding outward. Right. Okay, Okay,

237
00:14:32,040 --> 00:14:34,760
Speaker 1: I'm with you, But actually I I sort of mispoke

238
00:14:34,800 --> 00:14:38,080
Speaker 1: because it actually the temperature does rise across the chromosphere,

239
00:14:38,080 --> 00:14:40,400
Speaker 1: and it can rise up to ten thousand kelvin, which

240
00:14:40,480 --> 00:14:44,600
Speaker 1: is even hotter than the photosphere beneath it. Uh. And

241
00:14:44,640 --> 00:14:47,280
Speaker 1: then we have the corona chuck your favorite. Yeah, that's

242
00:14:47,280 --> 00:14:50,240
Speaker 1: the final layer, Josh, and it extends several million miles

243
00:14:50,240 --> 00:14:53,880
Speaker 1: outward from the photosphere and you can see this. In fact,

244
00:14:53,880 --> 00:14:56,800
Speaker 1: I think they first discovered the corona during the first

245
00:14:56,880 --> 00:14:59,840
Speaker 1: solar eclipse. They were like, what the hell is that? Exactly?

246
00:15:00,680 --> 00:15:02,960
Speaker 1: How hot does that one? Josh? It's a two billion

247
00:15:03,000 --> 00:15:06,440
Speaker 1: degrees kelvin actually, which again it's very hot. Yeah, so

248
00:15:06,480 --> 00:15:08,240
Speaker 1: it's not actually cooling as it goes out. Word, I

249
00:15:08,280 --> 00:15:12,040
Speaker 1: completely misspoke. No, it's it's that's the I think that's

250
00:15:12,080 --> 00:15:15,200
Speaker 1: one of the reasons why the Sun has these different

251
00:15:15,200 --> 00:15:18,040
Speaker 1: features like sun spots and solar prominences, which we're about

252
00:15:18,040 --> 00:15:21,560
Speaker 1: to talk about, is because these um cooling and heating

253
00:15:21,720 --> 00:15:26,240
Speaker 1: raising and rising and lowering convection cells are kind of

254
00:15:26,280 --> 00:15:30,400
Speaker 1: competing with one another, and they actually create the magnetism

255
00:15:30,440 --> 00:15:34,320
Speaker 1: that UM the plasma is attracted to or responds to,

256
00:15:34,440 --> 00:15:36,440
Speaker 1: I should say, right, And I don't feel too bad

257
00:15:36,440 --> 00:15:38,360
Speaker 1: because the article even says that no one knows why

258
00:15:38,360 --> 00:15:40,920
Speaker 1: the corona is so hot. No, because you would think

259
00:15:40,920 --> 00:15:43,160
Speaker 1: it would be cooler. But and there are hotter places

260
00:15:43,200 --> 00:15:47,480
Speaker 1: than others because the cooler spots are called coronal holes. Uh,

261
00:15:47,520 --> 00:15:51,360
Speaker 1: they're also let's talk about sun spots, chuck, Okay, sun

262
00:15:51,400 --> 00:15:57,120
Speaker 1: spots are UM these areas of magnetic activity along the photosphere, right,

263
00:15:57,360 --> 00:16:00,680
Speaker 1: darker and cooler. Right. Um, they always appear in pairs

264
00:16:00,720 --> 00:16:02,760
Speaker 1: as far as I know, although I think they can

265
00:16:02,840 --> 00:16:06,400
Speaker 1: appear singularly, but it's very uncommon because it's a monopole. Right.

266
00:16:06,560 --> 00:16:09,640
Speaker 1: Like I said that, there's that um that convection activity

267
00:16:10,280 --> 00:16:14,160
Speaker 1: that actually creates the magnetic fields around the sun, right right,

268
00:16:14,560 --> 00:16:17,280
Speaker 1: And so when sun spots appear, generally they appear in

269
00:16:17,280 --> 00:16:20,520
Speaker 1: in pairs because one represents magnetic north and the other

270
00:16:20,680 --> 00:16:25,280
Speaker 1: represents magnetic south. And along these magnetic fields, other solar

271
00:16:25,320 --> 00:16:28,880
Speaker 1: activity can occur. Right, You've got solar prominences, which is

272
00:16:28,920 --> 00:16:33,600
Speaker 1: actually an arc of uh. I think particles and radiation

273
00:16:34,120 --> 00:16:37,840
Speaker 1: that can extend, uh, I think a thousand kilometers outside

274
00:16:37,880 --> 00:16:40,800
Speaker 1: of the Sun's atmosphere. Right, Yeah, they can, and they

275
00:16:40,880 --> 00:16:43,760
Speaker 1: last for two or three months. It's like a temporary thing, right.

276
00:16:43,840 --> 00:16:47,520
Speaker 1: And these things are it's kind of like um, an

277
00:16:47,600 --> 00:16:51,800
Speaker 1: arc of electricity, except a lot bigger, right right. Uh.

278
00:16:51,840 --> 00:16:54,920
Speaker 1: And every once in a while they erupt into coronal

279
00:16:54,960 --> 00:16:58,520
Speaker 1: mass ejections, right, which is my next band name? Is it?

280
00:16:58,680 --> 00:17:02,360
Speaker 1: Coronal mass ejection? That's give? Uh? Can we? I got

281
00:17:02,440 --> 00:17:03,840
Speaker 1: one more thing on sun spots, which I thought was

282
00:17:03,880 --> 00:17:06,680
Speaker 1: really cool is you know, they break through their magnetic

283
00:17:06,920 --> 00:17:10,959
Speaker 1: fields that breakthrough the surface, but they can only enter, exit,

284
00:17:11,040 --> 00:17:13,680
Speaker 1: and re enter through other sun spots, which I thought

285
00:17:13,760 --> 00:17:16,320
Speaker 1: was pretty cool. That is pretty cool. They also occur

286
00:17:16,440 --> 00:17:19,480
Speaker 1: on eleven year cycles, right, yes, the solar cycle a

287
00:17:19,520 --> 00:17:22,280
Speaker 1: full cycle, a full solar cycles twenty two years, so

288
00:17:22,320 --> 00:17:26,120
Speaker 1: every eleven years that either peaks or troughs. And what's

289
00:17:26,160 --> 00:17:31,600
Speaker 1: interesting is, um, you know, everybody's like the world's gonna

290
00:17:31,640 --> 00:17:33,920
Speaker 1: and I think we mentioned this in our twenty twelve podcast.

291
00:17:34,560 --> 00:17:39,000
Speaker 1: That is the predicted peak of the solar cycle maximum

292
00:17:39,040 --> 00:17:43,240
Speaker 1: that we're in. So you've got these sun spots, the

293
00:17:43,359 --> 00:17:46,120
Speaker 1: sun spot activity is gonna pick up. When sun spots

294
00:17:46,240 --> 00:17:49,679
Speaker 1: pick up, Solar prominences pick up. When there's more solar prominences,

295
00:17:49,680 --> 00:17:53,520
Speaker 1: there's more coronal mass ejections. When there's more coronal mass ejections,

296
00:17:53,800 --> 00:18:01,520
Speaker 1: the Earth is inundated with um uh radiation and radioactive articles. Right,

297
00:18:01,640 --> 00:18:04,040
Speaker 1: they hit the Earth's atmosphere and actually mess with the

298
00:18:04,080 --> 00:18:09,360
Speaker 1: magnetic field. This accounts for the Aurora borealis and Australia's right, right,

299
00:18:09,480 --> 00:18:12,760
Speaker 1: and um When enough of them hit the Earth's atmosphere

300
00:18:12,800 --> 00:18:17,239
Speaker 1: and they actually ionize, they interfere with our electrical activity, right,

301
00:18:17,400 --> 00:18:19,560
Speaker 1: calls like blackouts, right, which is why a lot of

302
00:18:19,560 --> 00:18:23,720
Speaker 1: people think that will have all these catastrophes. Right, that

303
00:18:23,760 --> 00:18:26,280
Speaker 1: makes sense, But really it's just part of a twenty

304
00:18:26,280 --> 00:18:29,800
Speaker 1: two year cycle of the sun. So calm down, are

305
00:18:29,840 --> 00:18:34,800
Speaker 1: your minds exactly know? The mines don't think that? That's right? Josh? Yes,

306
00:18:34,880 --> 00:18:36,160
Speaker 1: you want to talk about the color of the sun

307
00:18:36,200 --> 00:18:38,520
Speaker 1: real quick. Yeah, because this is a cool little fact

308
00:18:38,760 --> 00:18:40,639
Speaker 1: that I bet most people don't know, because most people

309
00:18:40,680 --> 00:18:43,800
Speaker 1: say the sun is yellow or orange. Not true. The

310
00:18:43,800 --> 00:18:47,560
Speaker 1: sun is actually white. Sunlight is actually white. Do you

311
00:18:47,600 --> 00:18:50,920
Speaker 1: know why it changes the atmosphere? Oh? Yeah, The atmosphere

312
00:18:50,920 --> 00:18:53,000
Speaker 1: acts as a filter for the setting sun and that's

313
00:18:53,000 --> 00:18:56,480
Speaker 1: when it changes its color. Well, and it is white.

314
00:18:56,520 --> 00:18:58,480
Speaker 1: It does appear white, but it's actually made up of

315
00:18:58,520 --> 00:19:01,040
Speaker 1: all the colors of the spectrum, which is why you

316
00:19:01,080 --> 00:19:04,879
Speaker 1: can take a prism and um shoot sunlight through it

317
00:19:04,920 --> 00:19:08,240
Speaker 1: and it spreads into the different colors and you have

318
00:19:08,520 --> 00:19:10,880
Speaker 1: pink Floyd's Dark Side of the Moon album cover. Right.

319
00:19:11,400 --> 00:19:15,160
Speaker 1: I got another couple of cool facts. Rotation of the sun.

320
00:19:15,280 --> 00:19:17,800
Speaker 1: Everyone knows it makes a complete rotation in about a month.

321
00:19:18,320 --> 00:19:22,639
Speaker 1: But because it's a gas. Basically, it's different parts rotate

322
00:19:22,680 --> 00:19:25,800
Speaker 1: at different rates. So gas near the equator takes twenty

323
00:19:25,840 --> 00:19:28,320
Speaker 1: five days to rotate, let's say, and gas at higher

324
00:19:28,359 --> 00:19:31,720
Speaker 1: latitudes may take as many as like three more extra days. Right,

325
00:19:31,920 --> 00:19:34,520
Speaker 1: pretty cool. So it's rotating at different rates. It is

326
00:19:34,760 --> 00:19:37,760
Speaker 1: because it's a ball of gas, exactly. And I got

327
00:19:37,760 --> 00:19:41,040
Speaker 1: one more You ready for this one about the vibration. Yeah,

328
00:19:41,080 --> 00:19:43,399
Speaker 1: this is pretty cool too. I thought I had no idea.

329
00:19:43,480 --> 00:19:47,719
Speaker 1: The sun vibrates constantly like a bell that is continuously struck, right,

330
00:19:47,760 --> 00:19:52,320
Speaker 1: creating sound ways. But there's two minutes between intervals, yes,

331
00:19:52,440 --> 00:19:55,480
Speaker 1: and ten million individual tones at the same time, So

332
00:19:55,960 --> 00:19:59,240
Speaker 1: we we could if our hearing was I guess different.

333
00:19:59,280 --> 00:20:01,119
Speaker 1: I don't know if better is the right word, but

334
00:20:01,160 --> 00:20:04,240
Speaker 1: if we had a different type of hearing, we would

335
00:20:04,320 --> 00:20:07,480
Speaker 1: be able to hear the vibrations coming off of the

336
00:20:07,520 --> 00:20:09,800
Speaker 1: Sun because actually do hit the Earth. But like I said,

337
00:20:09,840 --> 00:20:15,600
Speaker 1: in two minute intervals the slowest distance between intervals time

338
00:20:15,640 --> 00:20:21,000
Speaker 1: wise that humans can hear a second. So it's it's

339
00:20:21,040 --> 00:20:23,399
Speaker 1: constantly making a sound, we just can't hear. It just

340
00:20:23,480 --> 00:20:26,480
Speaker 1: leads me to the question, if the sun makes a

341
00:20:26,560 --> 00:20:30,920
Speaker 1: sound while it's vibrating, can you hear it. I bet

342
00:20:30,960 --> 00:20:34,399
Speaker 1: those blue people in Avatar can hear it. Now, you

343
00:20:34,440 --> 00:20:37,199
Speaker 1: still haven't seen it. I'll never see that movie. You

344
00:20:37,240 --> 00:21:09,440
Speaker 1: should never. You're gonna be that guy. Yeah, okay, that's fine.

345
00:21:12,760 --> 00:21:14,440
Speaker 1: I got a couple of other stats for you, Josh,

346
00:21:14,520 --> 00:21:17,080
Speaker 1: if you're into it. Well, not a fewer than five

347
00:21:17,119 --> 00:21:19,280
Speaker 1: percent of the stars in the Milky Way are brighter

348
00:21:19,400 --> 00:21:22,040
Speaker 1: or more massive than the Sun, but some are more

349
00:21:22,040 --> 00:21:25,760
Speaker 1: than one hundred thousand times is bright. Isn't that crazy? Yes,

350
00:21:25,960 --> 00:21:28,040
Speaker 1: that is pretty cool actually, And if you go in

351
00:21:28,080 --> 00:21:30,880
Speaker 1: the other way, some stars are less than one ten

352
00:21:31,640 --> 00:21:33,840
Speaker 1: as bright as the Sun, which is kind of nuts.

353
00:21:33,880 --> 00:21:36,600
Speaker 1: But really, I mean stat wise that we have a

354
00:21:36,600 --> 00:21:39,720
Speaker 1: fairly mediocre sun. Yeah, it does the trick, though, Yes,

355
00:21:39,720 --> 00:21:41,440
Speaker 1: it does s the trick, and it should for about

356
00:21:41,480 --> 00:21:44,359
Speaker 1: the next five billion years. Like we said, they or

357
00:21:44,440 --> 00:21:46,760
Speaker 1: the Sun is middle aged right now, right, it's about

358
00:21:46,800 --> 00:21:50,000
Speaker 1: halfway through. Sure, it's starting to look into wearing treck

359
00:21:50,040 --> 00:21:53,480
Speaker 1: suits all the time out in public exactly. Um, and uh,

360
00:21:53,720 --> 00:21:57,480
Speaker 1: after about five billion years, it's going to run out

361
00:21:57,520 --> 00:22:01,440
Speaker 1: of fuel, Yeah, run out of hydrogen. And what happens then, Well,

362
00:22:01,480 --> 00:22:03,639
Speaker 1: that density of the core is going to remain, but

363
00:22:03,720 --> 00:22:06,440
Speaker 1: it's not going to have the fuel to create these

364
00:22:07,000 --> 00:22:11,360
Speaker 1: um nuclear reactions, which remember we said that the Sun

365
00:22:11,520 --> 00:22:15,160
Speaker 1: is a bunch of nuclear reactions. This gravity smashing things

366
00:22:15,200 --> 00:22:19,760
Speaker 1: together and then the energy escaping. It's this constant pushing pull. Well,

367
00:22:19,800 --> 00:22:21,840
Speaker 1: when it runs out of fuel, there's gonna be nothing

368
00:22:21,840 --> 00:22:24,679
Speaker 1: but pull. There won't be any push any longer, right right,

369
00:22:24,680 --> 00:22:27,080
Speaker 1: which is bad news for the core. Right. But before

370
00:22:27,119 --> 00:22:30,000
Speaker 1: this happens, when this, when this kicks off, Chuck, it's

371
00:22:30,040 --> 00:22:33,760
Speaker 1: going to turn into a red giant. And this red

372
00:22:33,840 --> 00:22:35,760
Speaker 1: giant is you know how the Sun just kind of

373
00:22:35,760 --> 00:22:38,880
Speaker 1: heats the earth. Yes, well that's not gonna happen. I mean,

374
00:22:38,920 --> 00:22:41,160
Speaker 1: it'll heat the earth, but it's also going to vaporize

375
00:22:41,160 --> 00:22:43,480
Speaker 1: it when it turns into a red giant, which is

376
00:22:43,520 --> 00:22:46,119
Speaker 1: the bad news for us. Well, we probably won't be around.

377
00:22:46,119 --> 00:22:48,400
Speaker 1: We'll be long gone. There'll be no trace of humanity

378
00:22:48,480 --> 00:22:51,080
Speaker 1: anywhere in five billion years. In no way I would

379
00:22:51,119 --> 00:22:52,720
Speaker 1: think not. I don't know that we have that much

380
00:22:52,760 --> 00:22:56,439
Speaker 1: staying power. Um. And so the Sun is going to

381
00:22:56,680 --> 00:22:59,879
Speaker 1: vaporize the Earth, which is probably pretty wicked cool this.

382
00:23:00,040 --> 00:23:03,960
Speaker 1: See when that does happen, Um, after that, the core

383
00:23:04,400 --> 00:23:06,960
Speaker 1: will be Then the core will turn into carbon. I

384
00:23:07,000 --> 00:23:10,720
Speaker 1: must spoke earlier, right right, which is cools cools it down, right,

385
00:23:10,800 --> 00:23:12,880
Speaker 1: and then as it cools, it will turn into a

386
00:23:12,880 --> 00:23:16,639
Speaker 1: white dwarf, and then a black dwarf eventually, Yes, and

387
00:23:16,680 --> 00:23:20,520
Speaker 1: then it'll just be some hulk that won't even resemble

388
00:23:20,560 --> 00:23:23,320
Speaker 1: our sun anymore. Right, And once this whole process starts,

389
00:23:23,320 --> 00:23:27,639
Speaker 1: it's gonna take uh several billion years to even complete

390
00:23:27,720 --> 00:23:31,000
Speaker 1: that process. So now it happens overnight or a probably

391
00:23:31,000 --> 00:23:33,080
Speaker 1: about ten billion years from now, the Sun will just

392
00:23:33,119 --> 00:23:36,960
Speaker 1: be this massive hulk of carbon, right, like my brain

393
00:23:37,080 --> 00:23:39,639
Speaker 1: is right now. Not so massive that can we be

394
00:23:39,680 --> 00:23:42,600
Speaker 1: done now? I think? So? Okay, I mean there's a

395
00:23:42,640 --> 00:23:45,760
Speaker 1: lot more. We didn't even touch on solar wind and

396
00:23:45,800 --> 00:23:47,760
Speaker 1: things like that, but we leave it up to the

397
00:23:47,800 --> 00:23:52,520
Speaker 1: listener to pursue these. Yeah, sure, the listener or stuff

398
00:23:52,520 --> 00:23:56,679
Speaker 1: from the Science Lab or soon to be forthcoming sister

399
00:23:56,920 --> 00:24:02,600
Speaker 1: podcast with the esteemed Robert Lamb and his esteemed editor

400
00:24:02,680 --> 00:24:06,200
Speaker 1: Alison louder Milk, And then we can just talk about noodling. Yeah,

401
00:24:06,480 --> 00:24:08,439
Speaker 1: we'll go back to what we do best. It's just

402
00:24:08,560 --> 00:24:12,840
Speaker 1: bumpkin stuff, So Chuck, Josh, I can barely get it out,

403
00:24:12,960 --> 00:24:19,400
Speaker 1: I know. The listener, May I feel so defeated. I'm

404
00:24:19,440 --> 00:24:22,560
Speaker 1: just gonna call this the best part of this podcast.

405
00:24:24,480 --> 00:24:29,920
Speaker 1: Uh this is on human Experimentation, and we actually, as always,

406
00:24:29,920 --> 00:24:32,439
Speaker 1: if we put out a call for some random weirdness,

407
00:24:32,440 --> 00:24:34,760
Speaker 1: there's someone out there that listens to the show that

408
00:24:34,800 --> 00:24:36,880
Speaker 1: has been there and done that. Remember the kid whose

409
00:24:36,880 --> 00:24:41,320
Speaker 1: father used him as a human shield. Why? Uh So

410
00:24:41,440 --> 00:24:43,800
Speaker 1: I've got this one from Rebecca and she says this.

411
00:24:44,320 --> 00:24:47,199
Speaker 1: I just listened to the podcast on Human Experimentation. It

412
00:24:47,280 --> 00:24:49,119
Speaker 1: was thrilled that you featured something I can relate to

413
00:24:49,200 --> 00:24:52,960
Speaker 1: because I'm a former NASA human test subject. We just

414
00:24:53,000 --> 00:24:55,480
Speaker 1: talked about NASA. I know, weird funny how that works.

415
00:24:56,000 --> 00:24:57,840
Speaker 1: In two thousand six, I spent three months in a

416
00:24:57,920 --> 00:25:02,480
Speaker 1: bed at a negative six degree tilt. Isn't that crazy?

417
00:25:02,840 --> 00:25:04,639
Speaker 1: The effects of the human body at that angle are

418
00:25:04,720 --> 00:25:07,160
Speaker 1: very similar to what an astronaut goes through after spending

419
00:25:07,560 --> 00:25:10,440
Speaker 1: extended periods of time and space, which makes me wonder

420
00:25:10,440 --> 00:25:13,720
Speaker 1: how they figure that out? You know, because they're NASA,

421
00:25:13,840 --> 00:25:17,200
Speaker 1: that's the answer. Eventually, NASA hopes to take that information

422
00:25:17,200 --> 00:25:20,600
Speaker 1: they got from my time in bed to help astronauts

423
00:25:20,760 --> 00:25:23,280
Speaker 1: stay in space longer and travel further. From the Earth

424
00:25:23,560 --> 00:25:26,800
Speaker 1: and one day even land on Mars. As a test subject,

425
00:25:26,840 --> 00:25:30,160
Speaker 1: everything I did, from surfing the internet, eating, reading, even

426
00:25:30,240 --> 00:25:34,360
Speaker 1: using the bathroom was at an angle tilt. Five days

427
00:25:34,359 --> 00:25:35,920
Speaker 1: a week, I was wheeled to a lab where I

428
00:25:35,960 --> 00:25:38,760
Speaker 1: was attached to an elaborate pulley system that pulled me

429
00:25:38,840 --> 00:25:41,840
Speaker 1: onto a treadmill. What that was bolted to the wall.

430
00:25:42,080 --> 00:25:43,800
Speaker 1: I walked, jog and ran a few miles a day

431
00:25:43,800 --> 00:25:46,800
Speaker 1: to help my body avoid muscle atrophy. Of course, uh not.

432
00:25:46,920 --> 00:25:49,440
Speaker 1: Everyone selected for the study was so lucky, though half

433
00:25:49,440 --> 00:25:51,520
Speaker 1: of them did not get to run in this on

434
00:25:51,600 --> 00:25:54,159
Speaker 1: this unique contraption, so they were just in bed the

435
00:25:54,200 --> 00:25:56,920
Speaker 1: whole time. The date of the engineers got from my

436
00:25:57,000 --> 00:25:59,480
Speaker 1: running will help NASA figure out what types of exercise

437
00:26:00,040 --> 00:26:03,680
Speaker 1: astronauts will have to do to uh experience like long

438
00:26:03,720 --> 00:26:06,680
Speaker 1: extended trips into space. So while I didn't love everything

439
00:26:06,720 --> 00:26:09,159
Speaker 1: about it, going to the restroom, for example, it is

440
00:26:09,160 --> 00:26:11,680
Speaker 1: a thrilling thing to have been a part of. I'm

441
00:26:11,720 --> 00:26:15,880
Speaker 1: a huge fan and I'd like to learn neat stuff. Rebecca,

442
00:26:16,040 --> 00:26:17,800
Speaker 1: did you have that last part? No? No No, no, she

443
00:26:17,800 --> 00:26:21,200
Speaker 1: said that, Okay, yeah, more neat stuff. Well, thanks, Rebecca,

444
00:26:21,560 --> 00:26:24,560
Speaker 1: hats off to you for helping our astronauts. She didn't

445
00:26:24,560 --> 00:26:26,240
Speaker 1: mention if how much she got paid, if at all,

446
00:26:26,320 --> 00:26:28,600
Speaker 1: but I mean, and she did NASA's deep pockets, buddy,

447
00:26:28,640 --> 00:26:30,800
Speaker 1: that's what I hear. Yeah. Well, if you have any

448
