Both these projects, the GMT Giant Magellan Telescope and ours, the TM, are ready to be advanced to the final design phase. So that's kind of a formal thing within NSF. You're in preliminary design, and we have been. You have a preliminary design review, and we did. And then after some contemplation, the NSF could, if they wish, advance you to the final design phase. So we're hoping they'll do that soon. I would say there's been a lot of activity in Washington that has occupied the NSF people with other matters, you know, in the in the last few weeks. Nevertheless, I think we're on course to, hear from them before too long.
Something went wrong!

And of all the topics, you know, that TMT is capable of unraveling in the universe?
They wrote up, ten years ago, a detailed science plan that said, here are the things we're gonna do. And this is taken very seriously by the engineering crew. They said, well, if you want to do this, that, and the other, what does the telescope have to do? And so they wrote specifications for the telescope based on doing the science. Perhaps you're familiar with this concept. But that was ten years ago, and it's fair enough to ask how much has science changed in ten years. Honestly, my special field, the field of, dark energy and cosmic expansion hasn't changed very much. But a field that has totally blossomed, of course, is exoplanets, the discovery of planets around other stars. So we wanted to make sure that even with the new understanding and the broader set of questions and kind of what we do know and don't know, that the telescope is still on the path to being powerful for that work.
So we did that. And, that was a very healthy exercise. We got over 200 people to help fix this old report. You won't be too surprised to learn that we concluded that the telescope is going to be able to do these new things very, very well. But but thinking farther down the line, this telescope is not for ten years or, you know, it's for fifty years. And so it's a matter of getting the science for today and then the potential for science for tomorrow. Because if you think about it, the technology also is advancing. So it's not just the science, but the technology for detectors and everything is getting, better.
And we are going to be in a position sooner or later, to have a second generation of instruments and to keep on making this telescope right up at the technological frontier. You know, if you think about, Palomar, we drove by
Yeah.
Poolsonside or wherever it was there. And I thought, gee, that's right downhill from from Palomar. That telescope was built in 1950. You know, still, it had led the world for quite a long time because the instruments kept getting better. They went from photographic plates to electronic detectors, all these things that we kind of know about and take for granted. And it isn't at the absolute forefront now, but it's still a very productive scientific, place. So I think the lesson from that is that these big telescopes at the frontier of what you can do today are gonna last for decades and they're gonna be it's a generational thing. And I really feel that myself that, I got to use the 200 inches telescope.
I didn't build it. I got to use the telescopes at Cerro Tololo in Chile and at Kitt Peak, and I didn't build those. But after a while, you know, you grow into a role where you do help to build the telescopes. And I did help the Magellan telescopes, and I was the head of the, optical and infrared at the at the Center for Astrophysics for a while. So, and I was on the actually, I'm kinda proud of this. I was on the the committee that wrote the report. This is how we take pride in ourselves. I was on the committee that wrote the report about what we should do after the Hubble Space Telescope.
And, of course, that eventually became the James Webb Space Telescope.
It's it's three d print.
Yeah. Very nice work there. It's not that color, actually.
Well, yeah. In space, no one could see where right. So it was wasn't it Hale who went a little bit over the edge, psychologically in the building of a hundred inch? Is is that what
Well, it was, in between the hundred inch and the 200 inch. So it was very here's the interesting story. If I can remember the guy's name, I will tell you, but I haven't got it quite at the top of my, mind. But there was at the the money for the 200 inch telescope came from the Rockefeller Foundation. And the Rockefeller Foundation did not wanna give the money to the Carnegie Institution, which had been running Mount Wilson where, Hale had been working. But Hale had another, pocket there where he said, well, I also have this California Institute of Technology I've helped build. And so the money, came to to Caltech for the, for the 200 inch telescope. And the grants officer at the Rockefeller Foundation was a physicist, and participated quite a bit in the design and, you know, approval of the, of the project.
And when Hale, became incapacitated, just he was having nightmares, he blew his brain as a job. Yeah. Well, he would call it that. He, this guy whose name I gotta remember came from the organization organization that was doing the funding to be the head of the project.
Mhmm.
Now for the TNT, the Gordon and Betty Moore Foundation was a very important part of getting this thing going, and I was the person at the Moore Foundation over the last Right. Well, since 2015 anyway. Not getting it started, but but sustaining it, for the TMT. Right. And I was the observer on the board, but, you know, did everything but vote. Right. And, when it came time to, well, of course, Ed Stone was the, executive, whatever we call ourselves, executive director. Executive director.
But, you know, when it was time for him to step down and they looked around, they thought, well, who could do this? They asked me to do it. So I used to be the funder, and now I'm the head of the Derek, of the project just like the guy for the 200
and I should remember. Hopefully, the same fate won't befall you, Bob, because that would be a tragic loss for all of, all of astrophysics. So speaking of your field, so you're one of the few people that can say you prove this guy, This is Albert. Good old Albert wrong. You, discovered effectively discovered the accelerating spacial of the universe courtesy of what we now, you know, think might be related to dark energy. But lately, there's been a little bit of a controversy as our British friends might say that maybe there is no dark energy. Maybe we live either in a universe where dark energy is evolving or doing something where or we live in a void, in which case, you know, well, you legitimately lost an OL process. You don't have to give one back.
But, but would your students you know, would your, your former, very close colleagues, Adam, Reese, who sat there last year and Brian Schmidt, who I direct to you last year as well. Yeah. Tell me, what would be what what what's the state of play of that field?
Well, I think the first one that you mentioned that the dark energy might be evolving over time, that has, some well, it's very interesting if it's true. And there's a statistical signal that, you know, matches up better with changing dark energy than with constant dark energy. It's, data from, DESE, this very large spectroscopic survey, and there's gonna be a lot more data. Yeah. So, you know, when there's a controversial result, well, you need more data, and sometimes the result gets stronger Yep. And sometimes it goes away. So I think we're at that kind of a point where, you should pay attention for sure. And this is really interesting, and we should encourage those dizzy people to keep going Right.
And do more of their analysis and more and more of the data taking. So I think that's really interesting and a and a big possibility. The other one that you mentioned that maybe we're in a void and, therefore
time scape. For listeners, I mean, I know it's called time scape cosmology. I hope to have the authors of this, you know, controversial, but but provocative in an interesting way. Yeah. So what's your take on this tons of
less interested in that. I think, you have to satisfy many constraints to, get a complete picture of the cosmology. So you heard of the microwave background. You gotta gotta do that all right there. Yeah. You gotta do that properly. You have to get the ages of things right.
That's right.
And the level of homogeneity that we observe has to somehow, be embedded into, an analysis of all the stuff. So it is true that if you, use this particular model for how things are arranged and how that affects the expansion, that you can get, an effect that looks like, cosmic acceleration. But you have to do all those other things too, it seems to me. And, the picture the broader picture of lambda, cold dark matter kind of picture seems to be a much more, comprehensive physical picture. Now that's not exactly an experimental, you know, test, but I think, it does matter that you do not just one thing, even if you do it as well or better, but that you, at the same time, satisfy all these other constraints, the ages of the stars and the clustering of galaxies and all that stuff that, we've been working so hard to turn from hand waving into real statistical, understand.
Right. And a lot of the the sort of analysis that goes into the time scape model for my listeners who may or may not be familiar with it, has to do with, you know, kind of, I would say, not in a pejorative sense, but manipulation of confidence intervals and, you know, Bayesian, reasoning applied to, you know, to this to this problem to then set a threshold at which you would exclude the proposition that at least, you know, dark energy is a cosmological constant according to what I've seen. But as you pointed out, it has to you know, it's very hard to break the standard model whether it's particle physics or cosmology. Right?
Yeah. And I think, looking at a particular dataset and showing that your model, fits it well is not the same thing as getting the whole physical picture, which, is not the work of one person or of 10. You know, it's of thousands who have worked so hard on all of this. So I think, we should reserve judgment. I I just that to me is less interesting, yeah, just personally, than the DESE result.
Mhmm. Another, you know, maybe more pressing, more important thing, you know, if dark energy goes away, if it evolves, well, it's not a cosmological constant, that's okay. It won't affect us for, what, a hundred billion years. But but there's something floating around in space, that's gotten in the news recently. It is related to this. This is a piece of Chelyabinsk meteorite, which I've gotten. This is actually a gift for you, Bob.
Oh, because, yeah, I'm not in for the window or something. That's cool.
Or This was delivered by The United States Postal Service. But this is actually a meteorite. This is from, the Campo De Cielo Fall in in Argentina. I give these away to those of you on my e on my email list. One more generous fellas is for you. And if you have a, that's to go to briankeen.com/yt for YouTube or list. But if you have a dot e d u email address like many of our proteges and and friends and colleagues do Yeah. I'll send you one of these for sure if you live in The United States.
So this is a real meteorite. I give it to him. He had to come all the way down and give a colloquium and say, you you gotta
You must have tons of this stuff. Literally. What illegal
yeah. It's illegal to get to to export them now, so I got a whole bunch of them. I have here a plate collected by, a former, denizen of Pasadena. Her name was, Margaret Burbage. You wanted Margaret's plates? Because this is Jeff Burbage's office. I don't know if you knew that. I area design
He did come here when Jeff and Margaret were here, but at in lot that might have been seventy four or five or three years.
Well, he yeah. So he passed away about fifteen years ago now. It's incredible. Miss him. And, Margaret passed away at the beginning of COVID. Not from COVID, but we misheard tremendously too. She was the original founder here. So she actually worked very closely with Vera Rubin.
And actually Vera did a sabbatical here. She couldn't get a professorship as you know. And so, but but the Burbage is very kind to her, and she credited them with with, Margaret. And especially, you know, Jeff wasn't an observer. He was a theorist. Right? But with teaching her how to do the spectroscopy, and actually, Margaret measured a lot of these rotation curves before, before Vera did.
Yeah. She's not filled out.
She just didn't really
I know that. And I remembered reading those Yeah. When I was a graduate student. And the penny didn't drop for me either in No. I should have thought more about what does it mean about the mass distribution Exactly. To have a a rotation curve of that shape at which I you know, I was just a kid. Yeah. But I should have thought of that.
But you literally have forgotten more than I know. Most people will ever know. But so I I talked to Michael Turner, not too long ago, friend. He's he's for and I told him, well, we were looking for these axions with the CMB polarization with the Simon's array and Simon's observatories, like and I was like, well, your paper was actually the first one. He's like, no. I wasn't you know? We went back and forth and I I showed him actually you have forgotten that you created this, this this term. Probably ours in the cons context ZIP code. Anyway, I'm gonna get back to dark matter.
Yes.
Dark matter is another thing that's quite controversial. You may know in the in the two different approaches. One is looking at the heavens, one is looking in the laboratory. We have experiments here to look for. What's what's the current thinking on dark matter? What can TMT do perhaps? What what what is the alignment with the future science goals of that amazing instrument?
That's a good question. For the dark matter, of course, something that we could measure is how clumpy it is. And, we could do that because, the telescope will have fantastically good angular resolution. So if you're looking at a bunch of stars, say a globular cluster where there are lots and lots of stars in the field very close to one another, and you measure their positions over time, you could see the effect of, a medium sized black hole or clumpy dark matter on the positions of the of the objects. So, you we're not gonna image the dark matter, but we're gonna see the effects of it. And, of course, that's the whole story here, for the physicists, trying to see the dark matter bump into a xenon nucleus, you know, something like that. Right here. Yeah.
That's a great idea. And we thought for a long time, I mean, decades now, that it was just around the corner Yeah. And it was gonna happen. And now, tremendous ingenuity has been, devoted to this and a lot of xenon, by the way, which is quite bad. Yes. It is quite but you can use it for something else after you're done. Right. The, you know, the there's still no evidence for the weekly interacting massive particles of the WIMPs that Michael Turner also, was very influential and and popularized.
You touched upon the DESE results recently Yeah. Which were phenomenal. They've been out for about a year. I'm devoting on a special explanation episode of the of the podcast in a couple of weeks. I don't know if it'll be out by the time this comes up. But one of the interesting conclusions has come from my colleague here, professor Dan Green, who claims that there's evidence for negative neutrino mass. So one of the main outcomes of DESE has to do with with neutrino mass as well as many others assigned schools. So you're shaking your head maybe.
Well, I I you know, not because I really know No. Or have a strong understanding, but, you know, it's very novel, and it could be so, I guess, but it's not an area where I have any expert.
No. But your I mean, your book was very formative in my in my, career early on as a graduate, so the extravagant universe. Wouldn't this be sort of the most extravagant thing that you could think about? Negative mass or or even, well, first address that. So how extravagant has the universe gotten more
or less extravagant in the twenty plus year to '26 Well, I you know, it is surprising to me, not that we've made so little progress because there has been progress. Yes. And this the signals have gotten stronger. The measurements are way, way better. You know, instead of having 10 supernovae, we've got the thousand in, in these samples, and we're soon gonna have tens of thousands and many more. So the evidence is really better, but what's, been surprising to me and what you're hinting at is that there's a conceptual gap. Where is the new idea that is so persuasive that everybody says, well, that must be the that must be the right story. And, you can think of other areas like the one you work in where the idea of inflation somehow seemed like just the right thing, and, you know, that is still, what everybody talks about.
And if you can make a measurement, which I know you want to, that shows that that's really the case, that'll be a big step forward. So going from, an idea that kinda sweeps the field, but, you know, still leaves room for speculation to a story where the evidence is so strong that, it really tells you what the story is, That takes a lot of effort and, so just having a good idea is one thing. Having a good idea that other theorists think is interesting, that's better. But even that doesn't prove it. You know? The thing that is and even when you have a prediction that's matched by the data, that doesn't exactly prove it, but it sure makes you think you're on the right track. And, you know, the last hundred years or so have been a fantastic story of, coming to some deep understanding of what the universe is. It's not exactly where it came from and so on, but, you know, people are care care about that too. And there are different models for how things could have begun.
The inflation model is the one a lot of people like to talk about, but, you know, there are. There'll be other So so I think, it you have to have a strong enough motive to carry out the observations, but you also have to keep an open mind about what it might mean.
That's right. And on that in the vein as we wrap up, I'm gonna be a good, you know, a co host here and not make you miss your coffee and cookies unless you're, legally entitled to Yes. Like, is another concomitant measurement that we'll get with the CMB hopefully, and DESI might get as well, and DESI, and that's, of neutrino mass themselves, negative or positive. But the but that as a study, I wanna ask you not in terms of technique or technology, but that would be the first time as far as I, you know, can be aware of that an elementary particles mass would have been measured by an astronomical, not a laboratory based experiment. And Yeah. Knowing the sociology of the field so well as you do, from your just illustrious career, what do you think would be the reaction? I mean, I've asked this a particle physicist too, but do you think it will be accepted? I mean, do you think that those dodgy, you know, people working in deep underground labs at the LHC or whatever, do you think they're really gonna, you know, really my my former, you know, coauthor on audiobook, or she at least read the read the intro of Galileo's dialogue, Fabiola Giannotti. Is she gonna is she gonna accept the measurement of the from from these, you know, astronomers looking around with a telescope?
Well, I don't know. You can't tell other people what to think. That's true. But, my guess is that the cultures are sufficiently different, and the ways of going about things are sufficiently different that it would take quite a long time Yeah. For that to happen. But look at the solar neutrinos, for goodness sakes. There, we don't exactly know the mass. We know the difference That's right.
Of the mass. Well, that's that's a real step forward, and that everybody accepts that now from the neutrino mixing. So, I would say these things that are at the boundary of the various tribes are the things where we have to be really cautious and helpful to each other. Mhmm. The physicists tend to think they know better. Yep. But, sometimes the results come from a more straightforward, way of doing things that astronomy is used to.
Yeah. And as you say that, there's thinking about the greatest breakthroughs did come about because of the comity of man and woman and the the agreement between formally disparate fields, everything from, you know, climate change to, as you say, neutrino mass, some differences, and then even things like speed of light, relativity, historically.
So Yeah. Right. That's very so that's a good lesson. Yeah. And that's why people should listen to your podcast.
And go to other people's talks. Someone just say, hey. Go get a help. You better go. That's ultimate in being, Bob Kirschner. It's always a pleasure to be with you. We should do this more awesome.
Thank you, Brian. Every time I come down to Interstate 5, I'll stop a beer.
Thank you. You're already here, folks. Thanks very much. Stay tuned for another episode of the Into the Impossible podcast with, yours truly. Thanks a lot,
