1
00:00:00,120 --> 00:00:04,400
Speaker 1: Yeah, welcome to Stuff from the Science Lab from how

2
00:00:04,440 --> 00:00:16,000
Speaker 1: stuff works dot com. Hey, guys, welcome to the podcast.

3
00:00:16,079 --> 00:00:17,800
Speaker 1: This is Alice and I don't know, the science editor

4
00:00:17,920 --> 00:00:20,160
Speaker 1: how stuff works dot com. And this is Robert Lamb,

5
00:00:20,200 --> 00:00:22,960
Speaker 1: science writer at how stuff works dot com. And you know, um,

6
00:00:23,280 --> 00:00:26,680
Speaker 1: it's really hard not to love Stephen Hawking. Indeed, he's

7
00:00:26,800 --> 00:00:31,280
Speaker 1: very lovable and intelligent, especially when you you know, you write, podcast, edit,

8
00:00:31,840 --> 00:00:34,280
Speaker 1: live and breathe science, you know, at least from nine

9
00:00:34,320 --> 00:00:37,160
Speaker 1: to six from you know, for a living. Then then

10
00:00:37,240 --> 00:00:39,120
Speaker 1: you know he's a pretty big deal. Yeah, he starts

11
00:00:39,159 --> 00:00:42,000
Speaker 1: to approach idle status, but like we're discussing earlier, it's

12
00:00:42,000 --> 00:00:44,760
Speaker 1: often easy to like fall into the trap of just thinking,

13
00:00:45,159 --> 00:00:49,040
Speaker 1: all right, this is a brilliant, brilliant brain in um,

14
00:00:49,080 --> 00:00:52,800
Speaker 1: you know, a a disabled body and uh, and then

15
00:00:52,840 --> 00:00:54,800
Speaker 1: sort of like dismiss a lot of like whatever he's

16
00:00:54,840 --> 00:00:58,040
Speaker 1: talking about. What are you talking about? Dismiss who's dismissing Hawking?

17
00:00:58,120 --> 00:01:01,600
Speaker 1: Who has the audacity seeing that? Not like logically saying

18
00:01:01,640 --> 00:01:05,680
Speaker 1: like Hawking, but more like people are just kind of like, oh, yeah,

19
00:01:05,720 --> 00:01:08,600
Speaker 1: Stephen Hawking, he's brilliant, but without really giving a lot

20
00:01:08,600 --> 00:01:10,640
Speaker 1: of thought to like what he's you know, actually why

21
00:01:10,680 --> 00:01:13,520
Speaker 1: he's brilliant or much less thinking about the man, the

22
00:01:13,560 --> 00:01:15,440
Speaker 1: man that this is. This is a real dude, and

23
00:01:15,440 --> 00:01:17,639
Speaker 1: it's more than a theoretical physics and he's a pretty

24
00:01:17,720 --> 00:01:20,840
Speaker 1: interesting guy. Yeah. So today we thought we'd walk you

25
00:01:21,319 --> 00:01:22,760
Speaker 1: through a couple of things that you might not know

26
00:01:22,760 --> 00:01:26,000
Speaker 1: about Stephen Hawking. Despite the title hanging with Stephen Hockey,

27
00:01:26,000 --> 00:01:28,880
Speaker 1: he's not actually here in the studio. He didn't respond

28
00:01:28,880 --> 00:01:34,240
Speaker 1: to our interview requests. Imagine that. Um. This is based

29
00:01:34,240 --> 00:01:37,240
Speaker 1: on article that Jane McGrath, former co host of Stuff

30
00:01:37,240 --> 00:01:39,680
Speaker 1: You Miston history class back in the day, and she

31
00:01:39,680 --> 00:01:42,400
Speaker 1: wrote an article for House to Parks called ten cool

32
00:01:42,440 --> 00:01:44,800
Speaker 1: things you didn't know about Stephen Hawking. So if you

33
00:01:44,840 --> 00:01:46,520
Speaker 1: are really into Hawking and you want to go check

34
00:01:46,520 --> 00:01:49,040
Speaker 1: it out after you listen to our podcast, do it. Yeah.

35
00:01:49,080 --> 00:01:50,840
Speaker 1: We also have a quiz about Stephen Hawking. We have

36
00:01:50,840 --> 00:01:53,280
Speaker 1: two quizes about Stephen Hawking, I think. So if you

37
00:01:53,520 --> 00:01:56,360
Speaker 1: feel like Stephen Hawking already know that stuff, well bring it,

38
00:01:56,520 --> 00:01:59,360
Speaker 1: you know, come to the website and test that knowledge out. Okay,

39
00:01:59,360 --> 00:02:01,960
Speaker 1: So what is the theoretical physicist known for? What do

40
00:02:02,000 --> 00:02:04,280
Speaker 1: you know him for? Black holes? Right? Yeah, black hole

41
00:02:04,320 --> 00:02:07,120
Speaker 1: research and also the whole limitless universe thing where the

42
00:02:07,440 --> 00:02:11,200
Speaker 1: boundless universe. We'll get into that a little bit. Yeah,

43
00:02:11,320 --> 00:02:13,360
Speaker 1: a little bit. We don't don't turn off the podcast.

44
00:02:13,400 --> 00:02:14,960
Speaker 1: We're not going to get heavy into that. But but

45
00:02:15,000 --> 00:02:18,120
Speaker 1: well we'll discuss it. Let's let's start out with the

46
00:02:18,720 --> 00:02:21,360
Speaker 1: day of his birth. It's kind of handy because this

47
00:02:21,400 --> 00:02:24,440
Speaker 1: guy was born three hundred years to the day after

48
00:02:24,520 --> 00:02:28,480
Speaker 1: Galileo died on January so that's kind of handy. I

49
00:02:28,480 --> 00:02:32,040
Speaker 1: did think about looking up to see who died on

50
00:02:32,040 --> 00:02:34,040
Speaker 1: on my birthday to see if I could somehow link

51
00:02:34,120 --> 00:02:38,400
Speaker 1: myself a big figure in the past, but I didn't

52
00:02:38,440 --> 00:02:40,560
Speaker 1: have time before the podcast. Oh that that's a bit

53
00:02:40,560 --> 00:02:43,400
Speaker 1: of a letdown. I was really getting excited. We'll say

54
00:02:43,440 --> 00:02:47,160
Speaker 1: that for another podcast. Um, but but yeah, that's that's

55
00:02:47,160 --> 00:02:49,080
Speaker 1: pretty big. You know. It kind of implies that he

56
00:02:49,160 --> 00:02:51,440
Speaker 1: had some big guest shoes to fill, and you know,

57
00:02:51,520 --> 00:02:55,399
Speaker 1: some people would say he kind of did. But interestingly enough,

58
00:02:55,440 --> 00:02:59,480
Speaker 1: this guy has never received a Nobel It is interesting. Yeah,

59
00:02:59,560 --> 00:03:02,800
Speaker 1: I mean, so he's one of the most famous physicists

60
00:03:02,800 --> 00:03:04,600
Speaker 1: out there, one of the most famous scientists out there,

61
00:03:04,639 --> 00:03:08,160
Speaker 1: but he's gotten lots of other awards and prizes and

62
00:03:08,200 --> 00:03:12,600
Speaker 1: recognitions that, but nothing about Yeah, so inducted into the

63
00:03:12,680 --> 00:03:15,640
Speaker 1: Royal Society at the wee age of in his thirties.

64
00:03:15,639 --> 00:03:17,000
Speaker 1: I think he was thirty two. He was. He was

65
00:03:17,000 --> 00:03:19,919
Speaker 1: a relative young feller. Although a lot of people who

66
00:03:19,960 --> 00:03:22,200
Speaker 1: are making their names in math and science, they say

67
00:03:22,680 --> 00:03:26,639
Speaker 1: have already done like their critical work when they're pretty young,

68
00:03:26,720 --> 00:03:29,600
Speaker 1: which I always find distressing because you know what, if

69
00:03:29,600 --> 00:03:31,959
Speaker 1: my best years are are gone, your best years of

70
00:03:32,000 --> 00:03:37,680
Speaker 1: scientific brilliance is gone. Um So. Another interesting thing is

71
00:03:37,680 --> 00:03:42,040
Speaker 1: he's held at Cambridge University's Lucaezian Professor of Mathematics position.

72
00:03:42,520 --> 00:03:46,800
Speaker 1: And this is pretty darn prestigious, especially when you consider

73
00:03:46,880 --> 00:03:49,080
Speaker 1: that Sir Isaac Newton was one of the guys who

74
00:03:49,120 --> 00:03:52,240
Speaker 1: has held it, and Charles Babbage, And do you know

75
00:03:52,240 --> 00:03:55,040
Speaker 1: who Babbage is? I needed a little refresh on Babbage.

76
00:03:55,280 --> 00:03:57,080
Speaker 1: It sounds familiar. I was just talking about him with

77
00:03:57,280 --> 00:04:00,240
Speaker 1: Jonathan Strickland of Tech Stuff this morning. He something to

78
00:04:00,280 --> 00:04:02,800
Speaker 1: do with computers, he does, he does. He was essentially

79
00:04:02,800 --> 00:04:06,320
Speaker 1: the guy who led to the modern computer. Yeah, well,

80
00:04:06,360 --> 00:04:08,840
Speaker 1: computers are great. But has he received an award from

81
00:04:08,840 --> 00:04:13,600
Speaker 1: the Pope? Indeed, I'm not sure Babbage has, but Hawking

82
00:04:13,640 --> 00:04:17,719
Speaker 1: has he and Roger Penrose did the pious eleven Gold

83
00:04:17,760 --> 00:04:22,200
Speaker 1: Medal for science. You know, we have to do some

84
00:04:22,200 --> 00:04:24,400
Speaker 1: some sort of something about the pope giving out medals

85
00:04:24,440 --> 00:04:26,159
Speaker 1: to science because this was curious. I've not heard of this,

86
00:04:26,240 --> 00:04:28,640
Speaker 1: had you? Um? Yeah, I was a famiere a little

87
00:04:28,680 --> 00:04:31,279
Speaker 1: bit with it. I know one thing we're talking about Galileo.

88
00:04:31,320 --> 00:04:33,440
Speaker 1: Galileo did not get an award from the Pope, at

89
00:04:33,520 --> 00:04:37,240
Speaker 1: least not in his day and time. Yeah, and Galileo

90
00:04:37,400 --> 00:04:40,719
Speaker 1: certainly did not get the Presidential Medal of Freedom from

91
00:04:40,839 --> 00:04:44,080
Speaker 1: US President Barack Obama in two thousand nine. Yeah, what's up, Obama?

92
00:04:44,320 --> 00:04:48,120
Speaker 1: Why are you not giving Galileos dues? I think he'd

93
00:04:48,120 --> 00:04:51,240
Speaker 1: take him even after his death. Of course, Hawking is

94
00:04:51,320 --> 00:04:53,720
Speaker 1: no stranger to the media. Have you guys seen him?

95
00:04:53,760 --> 00:04:55,279
Speaker 1: Have you Have you checked him out in any of

96
00:04:55,320 --> 00:04:57,840
Speaker 1: his many appearances on TV or in film? Yeah, I've

97
00:04:57,880 --> 00:05:00,560
Speaker 1: seen the Futurama episode that he's in where um, he

98
00:05:00,640 --> 00:05:02,440
Speaker 1: like teams up with Al Gore and a few other

99
00:05:02,640 --> 00:05:06,200
Speaker 1: notable celebrities to like go back in time and um,

100
00:05:06,279 --> 00:05:08,559
Speaker 1: we're going to the future to like save the world.

101
00:05:09,040 --> 00:05:11,200
Speaker 1: And so it's pretty funny. Um. So this episode really

102
00:05:11,200 --> 00:05:14,400
Speaker 1: made an impression on you. Yeah, yeah, yeah, well I

103
00:05:14,400 --> 00:05:18,440
Speaker 1: do remember specifically that Philip Fry, the kind of idiot

104
00:05:18,480 --> 00:05:21,960
Speaker 1: main character and Futurama. He uh, he discovers like a

105
00:05:21,960 --> 00:05:25,839
Speaker 1: cosmic achnology and calls it a fry hole, and and

106
00:05:25,880 --> 00:05:27,960
Speaker 1: then Hawking like steals it from him and calls it

107
00:05:28,000 --> 00:05:31,560
Speaker 1: a Hawking hole. That's good stuff. He's been on The

108
00:05:31,600 --> 00:05:35,080
Speaker 1: Simpsons four separate times. I heard the connection there was

109
00:05:35,080 --> 00:05:37,240
Speaker 1: that his daughter Lucy knew one of the scriptwriters from

110
00:05:37,279 --> 00:05:40,520
Speaker 1: the Simpsons. Um and he Hawking had a funny quote

111
00:05:40,560 --> 00:05:42,400
Speaker 1: and he said, as many people know me through the

112
00:05:42,400 --> 00:05:45,880
Speaker 1: Simpsons as through science, which is kind of hilarious. And

113
00:05:45,880 --> 00:05:48,960
Speaker 1: he also said Simpsons is the best thing on American TV. Yeah. Yeah,

114
00:05:49,000 --> 00:05:50,760
Speaker 1: he's a big fan. You can you can kind of

115
00:05:50,760 --> 00:05:53,320
Speaker 1: tell a lot about somebody if they have at least

116
00:05:53,440 --> 00:05:55,320
Speaker 1: dug the Simpsons at one point or another. I have

117
00:05:55,360 --> 00:05:57,520
Speaker 1: a friend who swears that she's never seen the Simpsons,

118
00:05:57,520 --> 00:06:00,200
Speaker 1: which I find to be a lie. How and that

119
00:06:00,279 --> 00:06:03,920
Speaker 1: be she has she has a TV, she has seen TV,

120
00:06:04,040 --> 00:06:06,400
Speaker 1: she has seen the Simpsons. How could you not have

121
00:06:06,440 --> 00:06:11,360
Speaker 1: seen the Simpsons? And then, of course, um, you wrote

122
00:06:11,360 --> 00:06:14,840
Speaker 1: a recent article that was based around his Discovery series

123
00:06:14,839 --> 00:06:17,240
Speaker 1: Into the Universe with Stephen Hawking, and this got a

124
00:06:17,279 --> 00:06:20,320
Speaker 1: lot of press because he was talking about some things

125
00:06:20,320 --> 00:06:22,760
Speaker 1: that people didn't want to necessarily hear about. Aliens. Yeah,

126
00:06:22,800 --> 00:06:24,680
Speaker 1: when we we did a podcast, yeah, talking about this

127
00:06:24,720 --> 00:06:26,400
Speaker 1: a little bit, but it basically boiled down to it

128
00:06:26,400 --> 00:06:29,520
Speaker 1: was a slow news week. Oil hadn't like leaked up

129
00:06:29,560 --> 00:06:31,719
Speaker 1: and polluted the golf yet, so everyone was like, what

130
00:06:31,720 --> 00:06:37,320
Speaker 1: are we gonna talk about that today? Aliens? Right? Um,

131
00:06:37,440 --> 00:06:40,120
Speaker 1: here's something you might not have known about Hawking. Along

132
00:06:40,200 --> 00:06:44,400
Speaker 1: with his whole appearances on TV and in film, he's

133
00:06:44,400 --> 00:06:47,280
Speaker 1: a children's author. Yeah, and I'm thinking, I'm kind of

134
00:06:47,360 --> 00:06:49,640
Speaker 1: excited about the books. So he's written too with his

135
00:06:49,720 --> 00:06:53,279
Speaker 1: daughter Lucy Hawking. Um. And the first one is George's

136
00:06:53,440 --> 00:06:56,159
Speaker 1: Secret Key to the Universe, and it's supposed to be

137
00:06:56,160 --> 00:06:58,280
Speaker 1: part of a trilogy built around this little boy George.

138
00:06:58,520 --> 00:07:00,680
Speaker 1: And the second one is out too, it's called George's

139
00:07:00,760 --> 00:07:03,120
Speaker 1: Cosmic Treasure Hunt. So I was curious because I was,

140
00:07:03,680 --> 00:07:06,360
Speaker 1: you know, I have some kids, know, some kids, I

141
00:07:06,480 --> 00:07:08,960
Speaker 1: gotta get them presents sometimes, you know, when things roll

142
00:07:09,000 --> 00:07:12,480
Speaker 1: around birthdays and such, And these started like good books

143
00:07:12,560 --> 00:07:15,760
Speaker 1: to get kids. Yeah, I mean it's supposedly like and

144
00:07:15,800 --> 00:07:17,280
Speaker 1: I haven't read them, but supposed to be each one

145
00:07:17,360 --> 00:07:20,560
Speaker 1: like deals with like real cosmological you know issues, like

146
00:07:20,600 --> 00:07:23,120
Speaker 1: they explain kind of how the universe works in you know,

147
00:07:23,400 --> 00:07:27,200
Speaker 1: far simpler terms. Yeah. They did an interview with ABC

148
00:07:27,480 --> 00:07:29,720
Speaker 1: Lucy and her I think Lucy and her dad did,

149
00:07:30,120 --> 00:07:32,120
Speaker 1: and Lucy says it was clear to me that there

150
00:07:32,200 --> 00:07:34,560
Speaker 1: was a wealth of science fiction available for children, but

151
00:07:34,640 --> 00:07:37,920
Speaker 1: not very much quote unquote science fact. Science fiction can

152
00:07:37,960 --> 00:07:40,000
Speaker 1: be exciting and very gripping, but it doesn't tell us

153
00:07:40,000 --> 00:07:42,240
Speaker 1: anything about the universe in which we live. We wrote

154
00:07:42,240 --> 00:07:44,320
Speaker 1: an adventure that is based on real science rather than

155
00:07:44,360 --> 00:07:48,800
Speaker 1: on fantasy. I don't know. I mean, do you think

156
00:07:48,840 --> 00:07:50,800
Speaker 1: that I kind of disagree with her on the whole

157
00:07:50,840 --> 00:07:53,440
Speaker 1: science fiction thing not being able to tell us about well,

158
00:07:53,480 --> 00:07:55,800
Speaker 1: the universe. It, No, it can, but I just don't

159
00:07:55,800 --> 00:07:57,920
Speaker 1: know how much I think. Maybe her point is more

160
00:07:58,400 --> 00:08:02,440
Speaker 1: when it comes to children's fiction, you know, you know,

161
00:08:02,560 --> 00:08:05,520
Speaker 1: like and I can't think of any like young adults

162
00:08:05,520 --> 00:08:07,440
Speaker 1: sci fi titles. Well, I don't know. I guess for

163
00:08:07,520 --> 00:08:09,440
Speaker 1: me when I was a young adult, like the sci

164
00:08:09,480 --> 00:08:11,760
Speaker 1: fi titles that I was into, or things like Asimov.

165
00:08:12,360 --> 00:08:14,760
Speaker 1: So so yeah, if you look at it that way,

166
00:08:14,760 --> 00:08:18,280
Speaker 1: it's like, you know, Asimov is perfectly fine for many

167
00:08:18,320 --> 00:08:20,240
Speaker 1: young people to read, and you know, and I think

168
00:08:20,400 --> 00:08:24,480
Speaker 1: reading as Amov has inspired you know, many scientists and

169
00:08:24,720 --> 00:08:26,360
Speaker 1: children who just you know, went on to other things

170
00:08:26,400 --> 00:08:29,840
Speaker 1: that remained interested in it. But the book that Hawking

171
00:08:29,920 --> 00:08:33,000
Speaker 1: is really well known for is, of course, Brief History

172
00:08:33,000 --> 00:08:35,680
Speaker 1: of Time. Right did you read it? Um? I don't

173
00:08:35,679 --> 00:08:37,600
Speaker 1: know if I've sat down and read it cover to cover,

174
00:08:37,760 --> 00:08:39,840
Speaker 1: but I've definitely hit it up here and there for

175
00:08:40,480 --> 00:08:44,360
Speaker 1: articles or you know, to answer little questions in my head. Um.

176
00:08:44,400 --> 00:08:45,880
Speaker 1: They made a movie out of it as well, which

177
00:08:45,920 --> 00:08:48,679
Speaker 1: I have not seen, but yeah, and there's a hawkings

178
00:08:48,679 --> 00:08:51,640
Speaker 1: and tons of documentaries. He's written all sorts of stuff.

179
00:08:52,480 --> 00:08:57,520
Speaker 1: But here's something this guy, this vaunted science celebrity, maybe

180
00:08:57,559 --> 00:09:01,880
Speaker 1: not always the best student. Yeah, everybody loves these stories.

181
00:09:02,000 --> 00:09:05,000
Speaker 1: Everybody does love these stories because whether you're a you know,

182
00:09:05,040 --> 00:09:07,600
Speaker 1: a kid who just got to see you know, in

183
00:09:07,880 --> 00:09:12,480
Speaker 1: in social studies, or you're a mom, or the argument

184
00:09:12,520 --> 00:09:14,839
Speaker 1: when you present your battery port to your parents. Hey,

185
00:09:14,880 --> 00:09:18,280
Speaker 1: you know, Steve Jobs never finished high school. Yeah, or

186
00:09:18,320 --> 00:09:20,440
Speaker 1: like when Einstein was a kidte Robbi convenient story, and

187
00:09:20,480 --> 00:09:25,600
Speaker 1: hockey wasn't even really that smart. Yeah, Bill Gates stole

188
00:09:25,640 --> 00:09:29,439
Speaker 1: the painting. You know, he turned out great. But as

189
00:09:29,480 --> 00:09:31,559
Speaker 1: it turns out, Hawking could actually get it done in

190
00:09:31,600 --> 00:09:35,040
Speaker 1: the grades department. When he took his scholarship exams, he

191
00:09:35,080 --> 00:09:37,520
Speaker 1: aised them and he had a near perfect score on

192
00:09:37,559 --> 00:09:40,440
Speaker 1: the physics portion. Yeah, when it came down to, uh,

193
00:09:40,520 --> 00:09:42,439
Speaker 1: you know, basically, be in a situation where you're not

194
00:09:42,480 --> 00:09:44,000
Speaker 1: going to get to go to the college you need

195
00:09:44,040 --> 00:09:46,560
Speaker 1: to go to unless you as this test, then he

196
00:09:46,640 --> 00:09:51,959
Speaker 1: ponied up and did it. So that's interesting because, um,

197
00:09:52,080 --> 00:09:55,040
Speaker 1: he didn't really want to study physics. Physics represented a

198
00:09:55,040 --> 00:09:58,120
Speaker 1: compromise between he and his dad, good old Frank. Yeah,

199
00:09:58,120 --> 00:10:00,440
Speaker 1: his dad wanted him to be a doctor. Yeah, I

200
00:10:00,480 --> 00:10:02,840
Speaker 1: mean you know that's a lot of parents want their

201
00:10:02,920 --> 00:10:05,440
Speaker 1: kids to go into medicine. Yeah, make that make the

202
00:10:05,480 --> 00:10:09,480
Speaker 1: big money. Right. But but then the yeah, that then

203
00:10:09,520 --> 00:10:11,560
Speaker 1: he was more interested in mathematics, like this, the whole

204
00:10:11,640 --> 00:10:14,199
Speaker 1: the hard cold you know when I mean not cold.

205
00:10:14,360 --> 00:10:15,880
Speaker 1: You know, if you're in love with mathematics, it's not

206
00:10:15,880 --> 00:10:18,040
Speaker 1: really a cold thing. But numbers can be warm and

207
00:10:18,080 --> 00:10:21,080
Speaker 1: fuzzy if you understand them. Yeah, they can be, yeah,

208
00:10:21,080 --> 00:10:23,240
Speaker 1: your best friends of your mathematician. But he was very

209
00:10:23,240 --> 00:10:25,680
Speaker 1: and you know, there's a lot of there's a lot

210
00:10:25,720 --> 00:10:28,120
Speaker 1: of potential in mathematics. There's a and then there's a

211
00:10:28,120 --> 00:10:31,040
Speaker 1: lot of you know, exact you know, calculation, and I

212
00:10:31,040 --> 00:10:33,160
Speaker 1: think he was really into that it wasn't so psyched

213
00:10:33,200 --> 00:10:36,080
Speaker 1: on biology, found it rather imprecise, and so Jane was

214
00:10:36,440 --> 00:10:39,280
Speaker 1: Jane was writing. So he ultimately wound up attending Oxford

215
00:10:39,280 --> 00:10:42,120
Speaker 1: and majoring in physics. And when it came to figure

216
00:10:42,120 --> 00:10:44,959
Speaker 1: out what physics path he wanted to go down, he

217
00:10:45,160 --> 00:10:48,480
Speaker 1: chose cosmology. Yeah, the big questions, you know, the big

218
00:10:48,520 --> 00:10:51,000
Speaker 1: overall what is he He's a big picture guy instead

219
00:10:51,040 --> 00:10:54,560
Speaker 1: of particle physics. So why there's a pretty interesting quote.

220
00:10:54,640 --> 00:10:57,280
Speaker 1: He gave a two thousand to lecture to Cambridge's Center

221
00:10:57,320 --> 00:11:01,120
Speaker 1: for Mathematical Sciences and he said, came about particle physics,

222
00:11:01,280 --> 00:11:04,240
Speaker 1: but I felt that elementary particles at that time was

223
00:11:04,559 --> 00:11:09,679
Speaker 1: too like Botany. That's kind of rough, kind of a rough,

224
00:11:10,200 --> 00:11:14,679
Speaker 1: very fair to the Botan Steither, but yeah, definitely even

225
00:11:14,720 --> 00:11:17,080
Speaker 1: more interesting it is this man who we've come to

226
00:11:17,120 --> 00:11:21,839
Speaker 1: know in a wheelchair. I'll be a crazy advanced wheelchair

227
00:11:22,360 --> 00:11:25,760
Speaker 1: he was a rower. Yeah, first year Oxford, he went

228
00:11:25,760 --> 00:11:28,160
Speaker 1: out for the crew team. Yeah he was. Yeah, he

229
00:11:28,200 --> 00:11:29,760
Speaker 1: was kind of like he wasn't like one of like

230
00:11:29,800 --> 00:11:32,520
Speaker 1: the muscle rowers, but he's a cockin. He's the one

231
00:11:32,520 --> 00:11:34,480
Speaker 1: who sat in the front because he was kind of

232
00:11:34,480 --> 00:11:37,960
Speaker 1: a small guy even then, and so his petite build

233
00:11:38,040 --> 00:11:40,000
Speaker 1: was good for sitting in the front of the boat

234
00:11:40,080 --> 00:11:44,880
Speaker 1: when you shout directions, whoa, whoa, give me lunch or

235
00:11:44,960 --> 00:11:48,000
Speaker 1: whatever you yell at your rowers. So yeah, it's it's

236
00:11:48,040 --> 00:11:50,480
Speaker 1: it's important, I think to realize that this, you know,

237
00:11:50,559 --> 00:11:52,320
Speaker 1: this guy was once You know, if you're all young,

238
00:11:52,400 --> 00:11:55,760
Speaker 1: young dude out there steering and not rowing a boat,

239
00:11:56,679 --> 00:11:59,400
Speaker 1: well do they I mean they kind of direct Well,

240
00:11:59,440 --> 00:12:01,480
Speaker 1: I mean he's steering. He's not like, you know, wiggling

241
00:12:01,520 --> 00:12:03,840
Speaker 1: and bum from side to side to steer the boat.

242
00:12:03,880 --> 00:12:06,080
Speaker 1: But still he's out there. You know, it's physical exertion,

243
00:12:06,120 --> 00:12:08,400
Speaker 1: it's probably cold, and you know, well, so he had

244
00:12:08,400 --> 00:12:10,440
Speaker 1: to drop it because rowing, as some of you guys

245
00:12:10,440 --> 00:12:12,800
Speaker 1: probably know, it cuts into your school work, all that practice.

246
00:12:12,840 --> 00:12:16,280
Speaker 1: It's fairly intense sport. So you had to drop it. Yeah,

247
00:12:16,400 --> 00:12:18,480
Speaker 1: But once upon a time, Stephen Hawking was a rower.

248
00:12:18,840 --> 00:12:20,800
Speaker 1: Let's get to the family life. There's some pretty good

249
00:12:20,800 --> 00:12:24,719
Speaker 1: stuff there. Yeah, Like the the author of our our

250
00:12:24,840 --> 00:12:28,240
Speaker 1: article about about Hawking. His wife's name was Jane. Yeah,

251
00:12:28,480 --> 00:12:31,120
Speaker 1: first wife. He met his wife Jane at a New

252
00:12:31,160 --> 00:12:37,000
Speaker 1: Year's party, wife Jane. According to Jane, it's funny. His wife,

253
00:12:37,080 --> 00:12:39,480
Speaker 1: Jane thought that Hawking was a funny guy and he

254
00:12:39,840 --> 00:12:43,280
Speaker 1: and she admired his independence and the sense of humor

255
00:12:43,360 --> 00:12:45,520
Speaker 1: is something that remains with him. I mean, obviously he's

256
00:12:45,559 --> 00:12:48,400
Speaker 1: cool with showing up on the Simpsons in Futurama, but

257
00:12:48,400 --> 00:12:50,440
Speaker 1: but you see other things he's written and even the

258
00:12:50,720 --> 00:12:53,360
Speaker 1: you know, the the TV show on Discovery of the

259
00:12:53,400 --> 00:12:56,000
Speaker 1: Hawkings Universe, and there's a certain sense of humor to

260
00:12:56,040 --> 00:12:59,280
Speaker 1: that as well. Yeah, it's pretty sharp. But Gec, he's

261
00:12:59,320 --> 00:13:02,520
Speaker 1: good with comeback. It wasn't long after he met Jane, though,

262
00:13:02,559 --> 00:13:04,839
Speaker 1: that he ended up going to the doctor to what

263
00:13:05,120 --> 00:13:07,360
Speaker 1: he was like tripping a lot. He was filmed kind

264
00:13:07,360 --> 00:13:09,440
Speaker 1: of clumsy, you know, like there's something wrong with his

265
00:13:09,559 --> 00:13:13,560
Speaker 1: like motor skills and h He was diagnosed with blue

266
00:13:13,559 --> 00:13:17,800
Speaker 1: Garrig's disease, also known as a l S. Yeah. Here,

267
00:13:17,800 --> 00:13:22,640
Speaker 1: I'll just attempt it. Amiotrophic lateral sclerosis and that was

268
00:13:22,679 --> 00:13:26,240
Speaker 1: at the wee age of twenty two. Yeah, and they

269
00:13:26,240 --> 00:13:29,559
Speaker 1: were not giving that kind of a forecast either thought

270
00:13:29,600 --> 00:13:31,720
Speaker 1: he maybe lived like twenty four or something, right, Yeah,

271
00:13:31,760 --> 00:13:34,640
Speaker 1: not necessarily long to even finish his PhD. He was

272
00:13:34,679 --> 00:13:37,960
Speaker 1: then at Cambridge. So according to Mayo Clinic, in case

273
00:13:38,000 --> 00:13:39,400
Speaker 1: you guys want to know the deal in a l S,

274
00:13:39,440 --> 00:13:43,000
Speaker 1: if you don't remember H, signs of ALIS start to

275
00:13:43,080 --> 00:13:45,839
Speaker 1: begin with your muscle twitching. Maybe you have weakness in

276
00:13:45,880 --> 00:13:48,840
Speaker 1: an arm or even slurring of speech, so that would

277
00:13:48,880 --> 00:13:52,440
Speaker 1: kind of explain the clumsiness. And then eventually the cells

278
00:13:52,480 --> 00:13:56,240
Speaker 1: that control muscle activity you know, good stuff like eating, swallowing, breathing,

279
00:13:56,280 --> 00:13:59,360
Speaker 1: all that stuff are affected and you essentially become parallels.

280
00:13:59,400 --> 00:14:03,120
Speaker 1: It's too general at yeah, it occurs in one to

281
00:14:03,200 --> 00:14:06,600
Speaker 1: three people for per one thousand, and the most common

282
00:14:06,640 --> 00:14:08,880
Speaker 1: cause of death UM if you have a LS is

283
00:14:08,920 --> 00:14:11,320
Speaker 1: a respiratory failure. So you guys won't remember back in

284
00:14:11,360 --> 00:14:13,720
Speaker 1: two thousand nine, there are a lot of news stories

285
00:14:13,720 --> 00:14:15,800
Speaker 1: when talking went at the hospital and he would fairly

286
00:14:15,840 --> 00:14:19,880
Speaker 1: serious respiratory infection UM. But he obviously survived it, and

287
00:14:20,400 --> 00:14:23,840
Speaker 1: interestingly enough, he's now he's Britain's oldest survivor of a LS.

288
00:14:24,360 --> 00:14:27,120
Speaker 1: He's a small feet because the life expectancy after your

289
00:14:27,120 --> 00:14:30,280
Speaker 1: diagnosed is a few years, not decades. Yeah, Like I

290
00:14:30,320 --> 00:14:33,280
Speaker 1: think like three to five tops, And he's been justifying

291
00:14:33,320 --> 00:14:38,600
Speaker 1: the odds for decades. Um. So despite the diagnosis, he

292
00:14:38,720 --> 00:14:41,480
Speaker 1: was like, whatever, I'm getting engaged to my lady Jane,

293
00:14:41,520 --> 00:14:44,320
Speaker 1: and he did. Yeah, And she pointed out in an

294
00:14:44,320 --> 00:14:45,800
Speaker 1: interview I think, or maybe it was in her book

295
00:14:45,800 --> 00:14:49,000
Speaker 1: that that also there was like this atmosphere of you know,

296
00:14:49,040 --> 00:14:51,520
Speaker 1: that we could have a nuclear war at any moment.

297
00:14:52,240 --> 00:14:53,920
Speaker 1: It could, it could all be over, so all the

298
00:14:53,920 --> 00:14:56,360
Speaker 1: more reason. It's like, you know, the person I love,

299
00:14:56,480 --> 00:15:00,040
Speaker 1: you know, has this condition, but you know, and and

300
00:15:00,360 --> 00:15:02,760
Speaker 1: then everything might you know, go up in flames tomorrow,

301
00:15:02,800 --> 00:15:04,800
Speaker 1: But you know, right now, we've got this moment. Let's

302
00:15:04,800 --> 00:15:08,240
Speaker 1: make the best of this. Romantic they lasted for a

303
00:15:08,280 --> 00:15:10,840
Speaker 1: long time, but they too wound up splitting, and then

304
00:15:10,880 --> 00:15:14,400
Speaker 1: of course Hawking married his nurse, Elaine Mason, five years later,

305
00:15:14,400 --> 00:15:17,680
Speaker 1: So this caused some chattering the folks that like to

306
00:15:17,680 --> 00:15:20,320
Speaker 1: talk about this stuff, and Hawking has since split from

307
00:15:20,320 --> 00:15:22,400
Speaker 1: Mason as well, and he's a couple of kids, a

308
00:15:22,400 --> 00:15:25,600
Speaker 1: couple of grandkids now too. Yeah, this is actually really

309
00:15:25,720 --> 00:15:30,600
Speaker 1: interesting right across another tidbit about Hawking's musical taste, given

310
00:15:30,680 --> 00:15:34,320
Speaker 1: his you know, his own um um you know, musical explorations.

311
00:15:34,320 --> 00:15:37,280
Speaker 1: He's really big into like Wagner and some classical stuff, right,

312
00:15:37,800 --> 00:15:41,920
Speaker 1: But he was hanging out with his his son Tim,

313
00:15:41,960 --> 00:15:43,840
Speaker 1: and his Tim was listening to a lot of depeche

314
00:15:43,840 --> 00:15:46,200
Speaker 1: Mode all right. He wound up go into the depeche

315
00:15:46,240 --> 00:15:48,720
Speaker 1: Mode cos and the and Hawking says that he's like,

316
00:15:48,760 --> 00:15:51,640
Speaker 1: actually really digs depeche Mode now, So that's that's pretty cool.

317
00:15:52,200 --> 00:15:54,840
Speaker 1: I like the idea of like here setting sitting around

318
00:15:54,920 --> 00:15:56,680
Speaker 1: kind of jamming out everybody else. Ha said his ears

319
00:15:56,680 --> 00:15:59,320
Speaker 1: were ring for maybe twenty four hours after, So that's

320
00:16:00,360 --> 00:16:02,280
Speaker 1: you know, but if you gotta if you're gonna rock hard,

321
00:16:02,360 --> 00:16:06,440
Speaker 1: sometimes you gotta to roll with the punches, right Hawking. Yeah,

322
00:16:06,480 --> 00:16:08,680
Speaker 1: And and and come on, like some of those depeche

323
00:16:08,680 --> 00:16:11,240
Speaker 1: Mode songs are pretty somber, you know, so you should

324
00:16:11,240 --> 00:16:15,080
Speaker 1: be able to roll with that. Indeed. So wife Jane

325
00:16:15,120 --> 00:16:17,120
Speaker 1: eventually wrote this tell all about what it was like

326
00:16:17,200 --> 00:16:18,960
Speaker 1: to be married to the brilliant scientists, and it was

327
00:16:19,000 --> 00:16:21,800
Speaker 1: called Music to Move the Stars. Six hundred and ten

328
00:16:21,880 --> 00:16:23,920
Speaker 1: pages of detail on what it was like to be

329
00:16:23,960 --> 00:16:27,400
Speaker 1: married to Stephen Hawking, and from when I gather from

330
00:16:27,440 --> 00:16:31,040
Speaker 1: reading some of the reviews, it wasn't all positive. I

331
00:16:31,080 --> 00:16:33,720
Speaker 1: can't imagine what it would be like to live with

332
00:16:33,840 --> 00:16:38,440
Speaker 1: such a ridiculously smart mind. I mean, just say it

333
00:16:38,520 --> 00:16:42,720
Speaker 1: caused you to, you know, lack faith in your own judgment.

334
00:16:42,800 --> 00:16:45,120
Speaker 1: Do you question yourself? I mean there have to be

335
00:16:45,160 --> 00:16:48,280
Speaker 1: all sorts of issues that come up with a relationship

336
00:16:48,400 --> 00:16:51,640
Speaker 1: like that, or maybe it's just two people. Yeah, I

337
00:16:51,640 --> 00:16:54,920
Speaker 1: guess I would tend to, you know, It's it's always

338
00:16:54,960 --> 00:16:57,120
Speaker 1: been my experience that if somebody is really smart about

339
00:16:57,240 --> 00:16:59,840
Speaker 1: some things, they're probably pretty dumb about others about others,

340
00:17:00,000 --> 00:17:03,640
Speaker 1: you know, so it all evens out. Yeah, maybe so?

341
00:17:03,800 --> 00:17:06,960
Speaker 1: Maybe so. Anyway, he's since reconciled with wife Jane, and

342
00:17:07,000 --> 00:17:09,920
Speaker 1: she was at his bedside when he had that respiratory infection.

343
00:17:09,960 --> 00:17:12,480
Speaker 1: Back into us and nine. But let's depart from his

344
00:17:12,680 --> 00:17:17,320
Speaker 1: personal life before we get too many angry emails. Um,

345
00:17:17,440 --> 00:17:20,760
Speaker 1: let's get back to the physics. Yeah, in a nutshell,

346
00:17:21,040 --> 00:17:25,639
Speaker 1: the boundless universe theory that he's you know, attributed with,

347
00:17:26,680 --> 00:17:28,960
Speaker 1: it boils down to like think of the think of

348
00:17:29,000 --> 00:17:32,800
Speaker 1: the globe, right, yes, all right, Now, if you start

349
00:17:32,880 --> 00:17:35,040
Speaker 1: running around in a circle, you know on the globe,

350
00:17:35,240 --> 00:17:37,240
Speaker 1: we're not in a circle. But like you started just running,

351
00:17:37,359 --> 00:17:39,639
Speaker 1: then you would eventually loop around to where you were before,

352
00:17:40,160 --> 00:17:41,720
Speaker 1: and then you'd loop around to where you're before. You

353
00:17:41,840 --> 00:17:44,359
Speaker 1: just going forever. You know, you're never going to run off, right,

354
00:17:44,800 --> 00:17:50,200
Speaker 1: It's limitless, at least in a two D two dimensional framework.

355
00:17:50,520 --> 00:17:52,359
Speaker 1: Oh man, we should have called hi flat Stanley for this.

356
00:17:53,160 --> 00:17:54,920
Speaker 1: We should have called him flat Stam. He was busy.

357
00:17:55,200 --> 00:17:56,800
Speaker 1: I think he was going to Josh and Chucks the

358
00:17:56,840 --> 00:18:00,639
Speaker 1: Trie United to his agent. Wouldn't return my call. But um,

359
00:18:00,680 --> 00:18:02,840
Speaker 1: but yeah, so in a in a very two dimensional sense,

360
00:18:02,960 --> 00:18:08,040
Speaker 1: a globe is limitless. So uh, the boundless universe deal

361
00:18:08,240 --> 00:18:12,560
Speaker 1: is taking that idea and expanding it to a four

362
00:18:12,680 --> 00:18:15,479
Speaker 1: D universe and the universe right yeah, where you have

363
00:18:15,560 --> 00:18:18,600
Speaker 1: you know, three spatial dimensions in one of time. Right,

364
00:18:18,680 --> 00:18:23,000
Speaker 1: So universe has a contained entity but having no boundaries.

365
00:18:23,080 --> 00:18:26,360
Speaker 1: So I think that your analogy really helps to kind

366
00:18:26,359 --> 00:18:28,800
Speaker 1: of frame that in my mind and hopefully in listeners

367
00:18:28,800 --> 00:18:32,320
Speaker 1: minds too. I mean, it's contained, yet it has no boundaries,

368
00:18:32,359 --> 00:18:34,400
Speaker 1: So that's tricky. Yeah, it's it's a pretty big topic.

369
00:18:34,440 --> 00:18:35,760
Speaker 1: We may have to cover that one on its own

370
00:18:36,119 --> 00:18:40,000
Speaker 1: in a future podcast. So what about the black hole business?

371
00:18:40,080 --> 00:18:43,119
Speaker 1: What about the black hole bet? Oh? Yeah, so this

372
00:18:43,200 --> 00:18:47,080
Speaker 1: is this is in. It had to do with whether

373
00:18:47,160 --> 00:18:50,360
Speaker 1: information is lost in a black hole, right, So that's

374
00:18:50,400 --> 00:18:54,080
Speaker 1: what Hawkings said back in He essentially said that, well,

375
00:18:54,200 --> 00:18:57,680
Speaker 1: black holes, they're not exactly black. I mean they're radiating

376
00:18:57,800 --> 00:19:00,800
Speaker 1: energy because we tend to think of them as these

377
00:19:01,280 --> 00:19:07,280
Speaker 1: yawning malls of blackness sucking everything within, you know, remotely

378
00:19:07,320 --> 00:19:13,160
Speaker 1: close into it, right, tremendous cosmological forces. So Hawking thought

379
00:19:13,280 --> 00:19:16,280
Speaker 1: black holes radiated energy. But here's the tricky thing. At

380
00:19:16,280 --> 00:19:18,560
Speaker 1: the same time, he said that information was lost in

381
00:19:18,560 --> 00:19:22,680
Speaker 1: the black hole, so it's creating this nice little paradox. Yeah,

382
00:19:22,760 --> 00:19:27,119
Speaker 1: and us, the theoretical physicist John Preskill did not agree.

383
00:19:27,359 --> 00:19:29,720
Speaker 1: He even made a bet with Hawking, uh as well

384
00:19:29,760 --> 00:19:35,040
Speaker 1: as with cal Tech theorist Kip Thorne in that the

385
00:19:35,160 --> 00:19:39,240
Speaker 1: information can in fact escape from black holes. And this

386
00:19:39,280 --> 00:19:41,720
Speaker 1: was nice because pres Skill's idea didn't break the laws

387
00:19:41,760 --> 00:19:46,280
Speaker 1: of quantum mechanics as um as Hawking and Thorne we're doing.

388
00:19:46,680 --> 00:19:49,800
Speaker 1: And so eventually a two thousand four rolls around. Hawking said, yeah,

389
00:19:49,840 --> 00:19:54,560
Speaker 1: pres Skill was right. I'm not sure that Thorne has conceded. Actually, yeah,

390
00:19:54,560 --> 00:19:56,520
Speaker 1: I also couldn't find like what kind of money was

391
00:19:56,560 --> 00:20:00,240
Speaker 1: at stake here. I did there was an encyclopedia, and

392
00:20:00,520 --> 00:20:04,080
Speaker 1: the encyclopedia was to be given to the loser, so

393
00:20:04,240 --> 00:20:07,280
Speaker 1: the loser could look up information that he wasn't so

394
00:20:07,320 --> 00:20:09,960
Speaker 1: sure about. Oh so it's just kind of like a

395
00:20:10,040 --> 00:20:12,159
Speaker 1: kind of a petty, not a petty, but it's just

396
00:20:12,200 --> 00:20:15,000
Speaker 1: kind of like a joke result kind of. Yeah, yeah,

397
00:20:15,119 --> 00:20:16,639
Speaker 1: these are the kind of bets that sign just have.

398
00:20:17,240 --> 00:20:19,520
Speaker 1: They weren't like, it wasn't like a finger or anything. Okay,

399
00:20:19,560 --> 00:20:23,840
Speaker 1: that's good. So, as we mentioned earlier, Hawking also has

400
00:20:24,000 --> 00:20:26,920
Speaker 1: talked a good deal about the possibility of extraterrestrial life

401
00:20:27,040 --> 00:20:30,119
Speaker 1: in our universe. And uh, and that always gets some

402
00:20:30,280 --> 00:20:32,600
Speaker 1: you know, when you have a dude that's considered by

403
00:20:32,600 --> 00:20:34,119
Speaker 1: many to be one of, you know, one of the

404
00:20:34,160 --> 00:20:37,320
Speaker 1: if not the most brilliant mind out there, scientific mind

405
00:20:37,720 --> 00:20:41,119
Speaker 1: and he starts talking about alien aliens actually existing, you know,

406
00:20:41,119 --> 00:20:42,920
Speaker 1: people take notice and they run with it on slow

407
00:20:42,960 --> 00:20:45,960
Speaker 1: news weeks and uh, he said, some has said some

408
00:20:45,960 --> 00:20:48,840
Speaker 1: really cool stuff. He he thinks that sure, it's a

409
00:20:48,840 --> 00:20:51,199
Speaker 1: big universe out there, we might not be alone. But

410
00:20:51,280 --> 00:20:54,080
Speaker 1: his big point has been that it might be primitive life,

411
00:20:54,119 --> 00:20:57,119
Speaker 1: not necessarily intelligent life. In fact, he famously equipped that

412
00:20:57,200 --> 00:20:59,879
Speaker 1: sense of humor again that intelligent life has yet to

413
00:21:00,000 --> 00:21:05,080
Speaker 1: occur on Earth at NASA's fiftieth anniversary lecture series. So, yes,

414
00:21:05,200 --> 00:21:07,080
Speaker 1: life might be out there, but it might be primitive.

415
00:21:07,440 --> 00:21:10,360
Speaker 1: And his another point of his which is well received,

416
00:21:10,880 --> 00:21:14,080
Speaker 1: was that those aliens, they might not be DNA based. We,

417
00:21:14,400 --> 00:21:16,440
Speaker 1: like we've talked about before in the podcast, we tend

418
00:21:16,520 --> 00:21:19,920
Speaker 1: to think of aliens being somewhat similar to humans. Who

419
00:21:20,000 --> 00:21:23,280
Speaker 1: who's to say, you know, pure energy beings. So you know,

420
00:21:24,200 --> 00:21:26,880
Speaker 1: this guy is kind of a limit, you know, ultimately, right,

421
00:21:26,920 --> 00:21:29,280
Speaker 1: So if these aliens aren't DNA based, then they could

422
00:21:29,280 --> 00:21:31,199
Speaker 1: bring a whole host of new diseases that could just

423
00:21:31,280 --> 00:21:33,720
Speaker 1: lay waste to the human population and life on Earth.

424
00:21:34,040 --> 00:21:36,560
Speaker 1: And uh and as we mentioned in the Into the

425
00:21:36,640 --> 00:21:40,440
Speaker 1: Universe with Stephen Hawking show and Discovery, he uh he

426
00:21:40,720 --> 00:21:44,639
Speaker 1: discussed at length how of intelligent life on another planet

427
00:21:44,680 --> 00:21:49,200
Speaker 1: followed the same evolutionary scent as as human life and

428
00:21:49,320 --> 00:21:54,119
Speaker 1: it in it in it it even resembled our cultural advances.

429
00:21:54,920 --> 00:21:57,480
Speaker 1: Then we would be looking at some pretty scary aliens

430
00:21:57,520 --> 00:22:00,439
Speaker 1: who would probably not be pleasant to meet, right. They

431
00:22:00,480 --> 00:22:02,760
Speaker 1: might not be looking to make friends, but rather mind

432
00:22:02,800 --> 00:22:05,280
Speaker 1: the Earth of its available resources, right, and move on

433
00:22:05,320 --> 00:22:07,720
Speaker 1: in their giant spaceships to mind other planets. It was

434
00:22:07,800 --> 00:22:09,640
Speaker 1: kind of a kind of a you know, it wasn't

435
00:22:09,720 --> 00:22:12,919
Speaker 1: everybody focused on that aspect of it, and but that

436
00:22:12,920 --> 00:22:16,960
Speaker 1: that aspect of of the talk was very nightmark, you know,

437
00:22:17,040 --> 00:22:19,840
Speaker 1: I mean, the idea of any foreign force coming and

438
00:22:20,000 --> 00:22:24,480
Speaker 1: harvesting your planet, that's that's spooky. Indeed. So if you

439
00:22:24,480 --> 00:22:26,639
Speaker 1: want to send us some email about Stephen Hawking or

440
00:22:26,760 --> 00:22:29,359
