Today, I'm chatting with Adam Brown who is a founder and lead of the Blue Shift team, which is cracking mass and reasoning at Google DeepMind and a theoretical physicist at Stanford. Adam, welcome. Delighted to be
here. Let's do this. Okay.
We'll talk about AI in a second. But first, let's talk about physics. Okay. First question. What is gonna be the ultimate fate of the universe? And, you know, how much confidence should we have?
The ultimate fate is a really long time in the future, so you probably shouldn't be that confident about the answer to that question. Uh-huh. In fact, our idea of the answer to what the ultimate fate is has changed a lot, in the last 100 years. About a 100 years ago, we thought that the universe was just static, wasn't growing or shrinking, was just sitting there statically. And then in the late twenties, Hubble and friends looked up at massive telescopes in the sky and noticed that distant galaxies were moving away from us and the universe is expanding. So that played big discovery number 1.
would they put this away?
Oh, okay. This this obviously depends on physics that we're not totally sure about yet. But it seems pretty consistent with the known laws of physics that the cosmonautial constant, what we perceive it as being a constant, this this this dark energy quantity that that pushing the universe apart from each other. In many very natural extensions of the known laws of physics, that is something that we have the ability to change. In fact, it can change, can take different values. It is not just totally fixed once and for all. That in fact, you have what's called different vacuum, different regions
Proceed with caution. But
definitely definitely proceed with caution. You know, in these theories where there's lots and lots of vacuums out there, and, most of those vacuums are incredibly inhospitable to life as we know it. In fact, seemingly, they're just completely inhospitable to all forms of intelligence. So you really, really don't want to end up in them. However, again, if our best theories are correct, it it seems as though there should be some of them that are much like our own in many ways, but have a, lower value of the cosmological constant. And so what we'd want to do is is engineer, that we end up in one
What what is a vacuum? Quick
