Now let's get started.
00:00:54.847 --> 00:01:00.987
This episode features the theoretical cosmologist, paul M Sutter.
00:01:00.987 --> 00:01:04.251
Larry Shea is the person who brought Paul to us.
00:01:04.251 --> 00:01:06.015
Can you please tell us what that means?
00:01:07.100 --> 00:01:11.790
I can't at all, and I'm going to make sure that Paul tells us exactly what it means.
00:01:11.790 --> 00:01:25.233
Look, we've been trying to get somebody on the show for a long time who's like this right, whether that be an astronaut or a theoretical cosmologist, whatever the case may be, I'm fascinated with the universe.
00:01:25.233 --> 00:01:45.203
I'm fascinated with the way the universe works, the physics of it and, funny enough, you know, we reached out to do this booking and we're thrilled when he came back and said he would do it and the day I got confirmation of the booking, I'm watching one of my favorite programs called how the Universe Works, and who pops on my screen?
00:01:45.203 --> 00:01:49.233
But Paul M Sutter, giving his opinion about, you know, dark matter.
00:01:49.233 --> 00:01:56.870
It was meant to be Dark matter and space and time, and yeah, so this guy is going to be super cool.
00:01:56.870 --> 00:01:58.206
We're going to have a really good time.
00:01:58.206 --> 00:02:02.921
He's super smart and really personable, we're hoping, so.
00:02:02.921 --> 00:02:07.091
I'm hoping he sheds some light on this fascinating career choice.
00:02:07.480 --> 00:02:12.469
I have to admit I don't know about you guys, but I'm kind of intimidated to speak to this guy because he is so smart.
00:02:12.469 --> 00:02:17.546
That's probably going to be one of the first questions I ask him Are we smart enough to actually speak to you?
00:02:17.546 --> 00:02:34.728
Because, let's be honest, you know he's mulling over the questions about how the universe started and it's it's so rare to have the opportunity to speak to someone of such a caliber, um, and kind of, you know, literally pick his brain about hey, how did you get into this?
00:02:34.728 --> 00:02:36.222
What does it mean to get into this?
00:02:36.222 --> 00:02:38.733
And in a lot of ways, you know, I gotta be.
00:02:38.733 --> 00:02:40.961
I'd have to think that he was always the smartest kid in the room.
00:02:40.961 --> 00:02:42.462
Uh, you know, even at this, this moment.
00:02:42.462 --> 00:02:44.466
So what's that like?
00:02:44.485 --> 00:02:45.687
Well, definitely in this moment.
00:02:47.008 --> 00:02:51.719
Oh yeah, you're right, speaking to us three, absolutely the smartest guy in the room.
00:02:51.719 --> 00:02:56.581
But you know, for the most part, you know what's that like to be the smartest person in the room, like all the time.
00:02:56.762 --> 00:02:58.524
Well, let's find out.
00:02:58.524 --> 00:03:02.169
Here is Paul M Sutter Now joining.
00:03:02.169 --> 00:03:07.175
No Wrong Choices is the theoretical cosmologist Paul M Sutter.
00:03:07.175 --> 00:03:30.106
Paul might be the busiest person on earth, or at least close to it, as he A advises NASA and the Department of Energy, hosts a variety of science shows on TV and digital, is an author, hosts a successful podcast, contributes to countless publications and is a globally recognized leader in the intersection of art and science.
00:03:30.106 --> 00:03:34.133
And, believe it or not, I left out a ton of stuff.
00:03:34.133 --> 00:03:35.804
Paul, thank you so much for joining us.
00:03:35.984 --> 00:03:41.627
Oh, thank you so much for having me, and I always have time for wonderful conversations like this All right.
00:03:41.647 --> 00:03:52.132
So, Paul, before we actually get into your background, the one thing we were talking before we got out, before we started speaking to you, was are the three of us collectively smart enough to speak to you after looking at your resume?
00:03:55.501 --> 00:03:56.663
No, I it's.
00:03:56.663 --> 00:04:04.609
This is weird because there is, I will admit, in academia, among scientists, I admit, a certain degree of snobbery.
00:04:04.609 --> 00:04:14.263
It's not easy to get a PhD in physics or astronomy or any of the hard sciences, and so we do like to wave around our PhDs and our doctorates.
00:04:14.263 --> 00:04:36.382
But where I find a lot of my fellow scientists failing when it comes to science communication and sharing what they've learned and engaging the public with what they've learned is assuming that other people are dumb and that they are empty vessels that you simply pour scientific knowledge into and then they will.
00:04:36.382 --> 00:04:39.531
Once that task is complete, they will come to the correct conclusion.
00:04:39.531 --> 00:05:07.475
It turns out that people are very intelligent, very smart, know when they're being lied to, know when they're being talked down to and spoken down to, and are very complex and come to their beliefs and their knowledge through a bunch of complicated twisting pathways, scientists included, and so I have a great deal of faith in the intelligence of my fellow humans.
00:05:07.699 --> 00:05:09.326
Obviously, you've not spoken with us before.
00:05:09.326 --> 00:05:11.946
Okay, yeah, that may be broken.
00:05:11.946 --> 00:05:12.689
That may be broken.
00:05:12.819 --> 00:05:15.867
You know, this is a hypothesis that I test with every interaction.
00:05:16.528 --> 00:05:16.930
I love it.
00:05:16.930 --> 00:05:19.649
I love it All right, so let's start with.
00:05:19.649 --> 00:05:28.651
You know yourself better than anyone, obviously, so why don't you take a second and just describe to the folks what it is that you do for a living, professionally?
00:05:28.651 --> 00:05:29.836
Who is Paul?
00:05:30.057 --> 00:05:30.959
M Sutter professionally.
00:05:30.959 --> 00:05:36.269
If I had to summarize it, it would be I am a searcher and a sharer.
00:05:36.269 --> 00:05:42.105
So I am deeply and intensely curious about the way the universe works.
00:05:42.105 --> 00:05:45.432
I've just always been fascinated by it.
00:05:45.432 --> 00:05:46.521
I know we'll dig into this.
00:05:46.521 --> 00:05:47.863
I've always been curious.
00:05:47.863 --> 00:05:49.286
I like to say.
00:05:49.286 --> 00:05:53.440
Scientists like myself are people who refuse to grow up.
00:05:53.440 --> 00:05:56.166
We just maintain that childlike curiosity.
00:05:56.166 --> 00:05:57.170
So I'm always asking.
00:05:57.170 --> 00:06:19.673
I always love learning new things and then I also love the sound of my own voice and I love talking and I love sharing and I love teaching and I love igniting a spark in other people and sharing that passion with them and seeing them get all ramped up and like, oh my, tell me more, I want to learn more, how can I find out more?
00:06:19.673 --> 00:06:21.507
And like that's a very, very special place for me.
00:06:21.507 --> 00:06:37.415
And so in my professional career I have tried to develop both of these sides of me, both the searching side, which I accomplish in my science and also in my writing, and then in the sharing and just getting it out there.
00:06:38.076 --> 00:06:38.276
All right.
00:06:38.276 --> 00:06:40.228
So let's take it back, then, to the beginning.
00:06:40.228 --> 00:06:43.507
As you said, you're an adult who's never had the chance to grow up.
00:06:43.507 --> 00:06:49.802
So then at some point, when you were a child, looking up at the stars, you said wow, you were just fascinated by what you saw.
00:06:49.802 --> 00:06:51.307
So what was that moment like?
00:06:51.307 --> 00:06:51.608
And?
00:06:51.608 --> 00:06:53.711
And at that time, and how old were you?
00:06:53.711 --> 00:06:59.663
And at that moment did you say to yourself this is kind of what I want to spend the rest of my life doing, even as a young child?
00:06:59.863 --> 00:07:03.971
yeah, yeah, as a young child there, there was no point like that.
00:07:03.971 --> 00:07:05.814
There was no moment.
00:07:05.814 --> 00:07:15.774
I was a super nerd growing up and what I remember about my childhood is I would read nonstop.
00:07:15.774 --> 00:07:21.591
I was devouring any book I could get my hands on.
00:07:21.591 --> 00:07:35.142
I was reading nonstop science fiction novels, but then I was also reading any book about science, any nonfiction book about history, about astronomy, about paleontology, about genetics.
00:07:35.142 --> 00:07:41.269
I just remember books being this source for me.
00:07:41.269 --> 00:07:49.427
Um, where I, you know I go, I go to school, I would learn and, you know, I would take the test and I would just want to know more.
00:07:49.427 --> 00:07:54.324
I just always wanted to, you know, expand a topic just a little bit more.
00:07:54.324 --> 00:07:59.062
I just wanted to always want to dig in a little bit deeper, and books were my avenue for that.
00:07:59.062 --> 00:08:09.935
But growing up, uh, I was fascinated by the night sky, but I was also fascinated by dinosaurs and optics and chemical reactions.
00:08:09.954 --> 00:08:11.237
The usual kid stuff, all of it.
00:08:11.701 --> 00:08:13.648
The usual kid stuff.
00:08:13.648 --> 00:08:25.333
And throughout my childhood, though, I grew up in rural Ohio, a town called Lancaster Ohio, southeast of Columbus.
00:08:25.333 --> 00:08:32.408
First I lived in Cleveland, then, when I was eight years old, we moved to central Ohio.
00:08:32.408 --> 00:08:45.754
It's just a rural town, decent-sized city, but not exactly connected to the rest of the world, especially high-powered academia and science.
00:08:45.754 --> 00:08:51.811
When you think elite science institutions, you do not think Lancaster Ohio.
00:08:51.811 --> 00:08:58.125
Sorry, lancaster Ohio, you're wonderful in some ways, but that is not one of them.
00:09:00.248 --> 00:09:08.567
I never, growing up all the way through my teenage years, made the connection that I could be a scientist.
00:09:08.567 --> 00:09:12.529
I just had this curiosity.
00:09:12.529 --> 00:09:27.801
I loved reading, I loved learning, I loved putting together new thoughts and having new thoughts wash over me, but I never thought that I could be a creator of new knowledge, that I could be one of those people.
00:09:27.801 --> 00:09:34.703
I always thought, assumed that scientists were just other people, smarter people, more capable, just different people.
00:09:34.703 --> 00:09:41.642
But being the nerd that I was, I ended up majoring in computer science.
00:09:41.642 --> 00:09:44.549
I wanted to be a computer programmer or software engineer.
00:09:44.549 --> 00:09:50.154
I've always had a thing for computers, for programming, an affinity for it.
00:09:50.154 --> 00:09:58.581
You know, joy and digging around in computers is one of the things I enjoy doing and I thought, oh, that's a job that people create software.
00:09:59.864 --> 00:10:09.889
And it wasn't until my third year of college I was like 20, 21 years old I took an elective, an astronomy class.
00:10:09.889 --> 00:10:15.931
It's one of those things where you have a list of options that you have to take to fulfill your major.
00:10:15.931 --> 00:10:16.993
I'm like, oh, astronomy.
00:10:16.993 --> 00:10:18.667
I remember astronomy.
00:10:18.667 --> 00:10:19.764
I remember reading books.
00:10:19.764 --> 00:10:22.047
I had a backyard telescope as a kid.
00:10:22.047 --> 00:10:23.390
I thought this would be fun.
00:10:23.390 --> 00:10:28.528
Turned out it was really fun and I was really enjoying myself in the class.
00:10:28.528 --> 00:10:29.783
I was talking to the professor.
00:10:29.783 --> 00:10:30.326
I remember this.
00:10:30.326 --> 00:10:33.808
I was at the time I was at California Polytechnic State University.
00:10:34.662 --> 00:10:50.923
That does mean I got as far away from Ohio as I possibly could At the moment I turned 18, I was gone, gone and I was taking this class and I actually entered cal poly as a computer science major.
00:10:50.923 --> 00:10:55.072
It's a very well renowned, uh computer science, uh, university.
00:10:55.072 --> 00:10:57.525
They have a wonderful department program there, uh.
00:10:57.525 --> 00:11:10.230
But then I just took this astronomy class with I remember his name, professor john polling, and I was, and I was what like two, three weeks in, and Professor Poling pulls me aside.
00:11:10.230 --> 00:11:12.388
We had been chatting a bunch about astronomy.
00:11:12.388 --> 00:11:17.111
He was like Paul, you seem to really enjoy this subject, this topic.
00:11:17.111 --> 00:11:19.840
I'm like, oh yeah, this is so fascinating.
00:11:20.260 --> 00:11:26.859
This was my first time that I had dug into science as a mathematical discipline.
00:11:26.859 --> 00:11:32.940
I had always approached it from popular science, from books, where you describe these high-level concepts.
00:11:32.940 --> 00:11:36.855
But it turns out actual science is grounded in mathematics.
00:11:36.855 --> 00:11:42.331
It is a mathematical exploration of nature, and this astronomy course was my first exposure to that.
00:11:42.331 --> 00:11:56.461
Like, oh, you're not just describing stuff in the universe, you're not just thinking about it, you're taking these and boiling it down to its mathematical essence and then you're using that to make predictions and understand things at a deeper level.
00:11:56.461 --> 00:11:58.345
And so this was mind-blowing to me.
00:11:58.345 --> 00:12:04.206
And Professor Polling says well, you know, we have a physics major here at Cal Poly.
00:12:04.206 --> 00:12:07.113
You can just switch majors if you want.
00:12:07.113 --> 00:12:09.225
This is your third year of school.
00:12:09.225 --> 00:12:16.868
Third year of college, wow, wow, third of seven, yeah, third of five.
00:12:16.988 --> 00:12:17.690
I finished in five.
00:12:17.690 --> 00:12:21.145
You're on the five-year plan I forgot how your leg thing's at.
00:12:22.740 --> 00:12:27.980
And I went back and started thinking about it, putting the back of my mind, you know.
00:12:27.980 --> 00:12:31.650
And then you know there's a midterm coming up, you start focusing on other stuff.
00:12:31.650 --> 00:12:46.456
A week later I wake up one morning and just my brain explodes and in that instant I became a scientist and I went to the admissions office or office or whatever office is in charge of that.
00:12:46.456 --> 00:12:53.520
I dropped two of my classes, I added a physics class and I switched majors to physics and I never looked back.
00:12:53.520 --> 00:12:54.503
I had no plan.
00:12:54.503 --> 00:12:57.269
I had no idea what I was going to do with it.
00:12:57.269 --> 00:13:06.091
I had no long-term career trajectory and dream of being a professor or a science communicator.
00:13:06.091 --> 00:13:09.970
I just wanted to learn more about physics.
00:13:10.932 --> 00:13:18.792
The very next semester I regretted it, partially because I had to start taking some very, very difficult physics classes.
00:13:18.792 --> 00:13:32.631
You know the kinds of physics classes that only the physics majors take in, the kind of classes designed to make you cry, designed to make you regret and like filter you out and weed you out, like no, this is, this is serious business.
00:13:32.631 --> 00:13:40.102
Um, you know, not serious like doctor or like lawyer or government serious, but like serious physics.
00:13:40.102 --> 00:13:40.924
So we're gonna leave you out camp.
00:13:40.945 --> 00:13:42.347
You went to physics boot camp, essentially right.
00:13:42.609 --> 00:13:43.450
Physics boot camp.
00:13:43.450 --> 00:13:44.231
It felt like that.
00:13:44.231 --> 00:13:48.181
But I got over that, you know.
00:13:48.181 --> 00:13:57.750
The tears came and went, moved on, and then I just found more and more joy doing this and then it blossomed into my career.
00:13:58.320 --> 00:13:59.903
What are some of the like.
00:13:59.903 --> 00:14:10.333
When I think about physics and I think about science and the type of work you do, your whole world sort of changes when you begin to understand some of those things.
00:14:10.333 --> 00:14:29.759
You know what were some of the early shocking revelations for you as you dug into physics and dug into science things I remember was from undergrad at cal poly, was um one being introduced to quantum mechanics.
00:14:30.421 --> 00:14:35.871
And quantum mechanics is fun and spooky and weird and it's great to talk about, uh.
00:14:35.871 --> 00:14:44.970
But then having a mathematical treatment of quantum mechanics where you start to play around with some of these fundamental equations, you're like oh and and.
00:14:44.970 --> 00:14:46.922
Then it was just like this evolving step.
00:14:46.922 --> 00:14:53.942
The more I got into the mathematics, the more things seemed very, very cool and powerful.
00:14:53.942 --> 00:15:04.390
I remember taking a class an introduction to general relativity, and we'd get homework problems like how long does it take for two black holes to spiral together?
00:15:04.390 --> 00:15:11.003
Or, if you were to pass through the event horizon of a black hole, calculate how long it takes for you to hit the singularity very common questions.
00:15:11.043 --> 00:15:17.883
I got those all the time, yeah I know I know this was before the weeder class, right, this was before that.
00:15:17.883 --> 00:15:22.148
This is for the everybody, the jed ed class, um.
00:15:22.148 --> 00:15:36.221
And I remember just feeling like you know those montages in superhero movies or animes where, like you know, they're like working out or they're getting new weapons and or like they're getting new tools.
00:15:36.221 --> 00:16:29.159
I felt like I was getting armed with new tools to approach the world, like, wow, I don't just talk about black holes, I'm able to calculate and make predictions about black holes, I'm able to make predictions about quantum mechanics, I'm able to say what's going to happen in this scenario, and just that unfolding of a deeper understanding of the way that nature works, where I can go out and enjoy a beautiful sunset and then also I can go back and I can calculate the diffraction and refraction of the light rays at different wavelengths and understand why the sunset has different colors, and that allows me to appreciate the sunset at an even deeper level and just the magic that we're even able to grapple with these kinds of concepts.
00:16:29.159 --> 00:16:30.724
And then it culminated.
00:16:30.764 --> 00:17:03.350
This train of thought culminated in graduate school, where I remember taking my first cosmology course with Dr Brian Fields, and this was at the University of Illinois, at Urbana-Champaign and I remember taking that class and now we were taking this, you know, mathematical description of nature to its ultimate expression, where we are writing down equations that describe the entire universe.
00:17:03.350 --> 00:17:15.423
Come on, wow, I mean 13 billion years of cosmic evolution, the expansion, this, the breadth, the scope, the forces involved, the gravity, everything, and we can boil it down to a single equation.
00:17:15.423 --> 00:17:32.304
We can say, aha, yes, so if you go out and measure this property, in this property this much, you put it into this equation and out pops an age of the universe and just the fact that this, these like vast time and distance scales, is like barely comprehensible scales, uh, that don't fit inside of a human mind.
00:17:32.304 --> 00:17:36.836
But then I can, I can write down an equation and I can.
00:17:36.836 --> 00:17:43.067
I have a tool that I can use to grapple and wrestle and interrogate the entire universe.
00:17:43.067 --> 00:17:47.994
Yeah, it was in that class that I became a cosmologist.
00:17:49.382 --> 00:17:51.692
Did you believe what you were discovering?
00:17:51.692 --> 00:17:57.949
You know, like, you're going through these equations and it's like how do you know that it's 13 billion?
00:17:57.949 --> 00:18:00.012
Like, did you believe it?
00:18:00.012 --> 00:18:06.663
And what convinced you that this was right and accurate, if that's even the right phrase to use?
00:18:06.703 --> 00:18:37.863
here concept of what we call first principles, which is, everything starts from the barest set of assumptions possible and then from there you unfold, you unpack, you develop the theory and you let the evidence lead the way.
00:18:37.863 --> 00:18:48.144
So in this case, in the case of cosmology, the cosmology class didn't start with hey, by the way, the universe is 13.77 billion years old.
00:18:48.144 --> 00:18:55.727
The cosmology class started with okay, we're going to start with general relativity.
00:18:55.727 --> 00:19:00.481
We are going to start with some basic assumptions about the universe.
00:19:00.481 --> 00:19:03.749
Here's how we're going to test those assumptions.
00:19:03.749 --> 00:19:09.189
Now that we've verified those assumptions, we're going to fold those into the mathematics and see what we get.
00:19:09.189 --> 00:19:15.511
And then we're going to derive some evolution equations and then we're going to unpack those further.
00:19:15.511 --> 00:19:19.588
And then we're going to take more observations, more data, and fit them in here.
00:19:19.588 --> 00:19:24.767
Say, ah, when you make this kind of observation, it fits into this parameter in the equation.
00:19:24.767 --> 00:19:36.044
You make that kind of observation and it modifies this parameter in the equation, and then we put all those together and then the end result 13.77 billion years it doesn't matter.
00:19:36.365 --> 00:19:38.315
It's just the number that pops out of the machine.
00:19:38.315 --> 00:19:41.670
But what matters are the observations, what matters is the equations.
00:19:41.670 --> 00:19:44.760
What matters is that this accurately describes the universe.
00:19:44.760 --> 00:19:46.424
That's what the class was about.
00:19:46.424 --> 00:19:53.589
The actual number that pops out at the end, that's a matter of debate, that's a matter of observation, that depends on the universe we live in.
00:19:54.111 --> 00:19:59.333
What we care about as physicists is do we have an accurate mathematical description?
00:19:59.333 --> 00:20:11.173
And so, because everything starts from first principles, I remember, exam after exam after exam, they would ask you a question and you don't get to start with the end.
00:20:11.173 --> 00:20:20.873
It says begin with first principles, where you have to start from the very beginning and re-derive everything and then be able to present your answer.
00:20:20.873 --> 00:20:29.423
And that is what matters present your answer, and that is what matters.
00:20:29.423 --> 00:20:40.333
And so, in that sense, I do believe that the equations that we have developed to describe the history of the universe seem to be relatively accurate, because they seem to be doing a good job of describing the actual universe that we observe.
00:20:40.333 --> 00:20:43.730
And then the number that pops out is the number that pops out.
00:20:44.643 --> 00:20:48.885
Wow, you're using the term, so I I want our education to continue as well.
00:20:48.885 --> 00:20:53.622
A theoretical cosmologist is different from an astrophysicist.
00:20:53.622 --> 00:20:54.022
How?
00:20:54.144 --> 00:20:54.825
great question.
00:20:54.825 --> 00:21:01.026
So there are lots of fields and subfields within physics and astronomy and there are a lot of overlaps in these fields.
00:21:01.026 --> 00:21:24.335
So a traditional astronomer is someone who is highly focused on instrumentation, on how do I build a good telescope, how do I gather high quality data, how do I make sure that what I'm producing and the images and the data and the spectra and all the stuff that I'm creating, how do I assure that I understand the uncertainties in it, the noise in it?
00:21:24.335 --> 00:21:26.521
How do I build a better telescope?
00:21:26.521 --> 00:21:28.567
That's like a classical astronomer.
00:21:29.830 --> 00:21:32.817
Then there are the astrophysicists.
00:21:32.817 --> 00:21:46.275
These are people who apply our knowledge of physics, the laws and theories that we have developed, and apply to all sorts of scenarios out in the universe, like, oh, we just saw a star explode.
00:21:46.275 --> 00:21:48.020
I wonder how stars explode.
00:21:48.020 --> 00:21:51.790
I wonder what physics happens to make that happen.
00:21:51.790 --> 00:21:54.035
Oh, our sun is really hot.
00:21:54.035 --> 00:21:55.618
I wonder why our sun is really hot.
00:21:55.618 --> 00:21:57.750
What are the physics to make our sun really hot?
00:21:57.750 --> 00:22:00.436
This is the job of the astrophysicist.
00:22:00.436 --> 00:22:06.011
Really hot, this is the job of the astrophysicist, and I've certainly done in my career a lot of astrophysics research.
00:22:06.031 --> 00:22:18.036
And then a cosmologist is a very broad term that describes someone who tries to understand the universe as a single physical object.
00:22:18.036 --> 00:22:22.394
So we are less concerned with the individual galaxies and stars that appear in the universe.
00:22:22.394 --> 00:22:24.905
We are less concerned with the individual galaxies and stars that appear in the universe.
00:22:24.905 --> 00:22:29.518
We are more concerned with the overall evolution and history of the universe.
00:22:29.518 --> 00:22:32.394
What was the universe like in its earliest moments?
00:22:32.394 --> 00:22:34.702
Why is it so big?
00:22:34.702 --> 00:22:36.547
Why does it have the size that it does?
00:22:37.328 --> 00:22:44.644
And within cosmology, again, there is this two sides an observational side and a theory side.
00:22:44.744 --> 00:23:03.217
There are people who are more aligned with traditional astronomy, who are trying to build massive surveys or maps of our universe, trying to get data of a very old light that is filtering through the cosmos and I've certainly participated in surveys like that.
00:23:03.905 --> 00:23:18.959
And then there is the more theoretical side, which is trying to develop theories of how the universe has evolved and what the universe is made of, and especially where I like to fit in, is trying to match up those theories to observation.
00:23:18.959 --> 00:23:20.565
So how do we test these ideas?
00:23:20.565 --> 00:23:23.374
How do we find new ways to validate?
00:23:23.374 --> 00:23:37.049
When you come up with a new idea Like, oh, I think the universe does this, or I think there's this component in the universe, or I think this happened, how do we match that with the observations that we do have, the data that we do have?
00:23:37.049 --> 00:23:40.897
How do we pick winners and losers in this kind of game?
00:23:40.897 --> 00:23:53.884
And that's where I like to fit in as a theorist of generating ideas about the universe and then going to the observational data and finding interesting ways to test those and validate those All right.
00:23:53.924 --> 00:23:55.351
So we were going to ask you a question.
00:23:55.351 --> 00:23:58.915
It's a question we kind of ask all of our guests, essentially like well, you're a good student in school.
00:23:58.915 --> 00:24:03.192
Now the obvious portion here is that, yes, you were a good student in school.
00:24:03.192 --> 00:24:10.169
Now the obvious, the obvious portion here is that, yes, you were a good student in school, but before you even got to college, were you a student who challenged your teachers?
00:24:10.169 --> 00:24:21.476
In that sense, were you, were you that kind of a student that was so, such a voracious learner and wanted to know so much that in many ways, your own teachers probably couldn't keep up with you in your, in your, in your want to learn?
00:24:22.925 --> 00:24:24.887
Teachers probably couldn't keep up with you in your want to learn.
00:24:24.887 --> 00:24:27.931
That is certainly true, and I don't want to brag about myself.
00:24:27.931 --> 00:24:33.457
I was not the top GPA in my class.
00:24:33.457 --> 00:24:36.599
I was not valedictorian, I didn't have the highest scores.
00:24:36.599 --> 00:24:38.040
I was an A student.
00:24:43.144 --> 00:24:44.650
Like in almost every single class, I would end up getting an.
00:24:44.650 --> 00:24:44.690
A.
00:24:44.690 --> 00:24:46.596
What was your worst class, by the way we?
00:24:46.596 --> 00:24:47.319
We thought it was jim.
00:24:47.319 --> 00:24:47.861
We thought it was.
00:24:47.861 --> 00:24:48.323
We thought it was.
00:24:48.323 --> 00:24:49.645
Uh, we thought it was jim.
00:24:49.685 --> 00:25:05.413
I was pretty terrible in pe I'll give you that um, but, uh, I actually I can't remember in high school what my worst class is, but I do remember in college my worst class was chemistry.
