#433 โ€“ Sara Walker: Physics of Life, Time, Complexity, and Aliens

Because our planet hasn't changed its physical size in 4 billion years, but there's a ton of of causation and recursion and time, whatever word you wanna use, information packed into this. And I think this is also embedded in sort of the virtualization of our technologies or the abstraction of language and all of these things. These things that seem really abstract are just really deep in time.

And so what that looks like is you have a planet that becomes increasingly virtualized And so it's getting bigger and bigger in time, but not really expanding out in space. And the rest of space is like kind of moving away from it. Again, it's a sort of exponentially receding horizon.

And I'm just not sure how far into this evolutionary process something gets, if it can ever see that there's another such structure out there.

Virtual as sort of a play on virtual reality. and like simulation theories. But virtual also in a sense of, you know, we talk about virtual particles in particle physics, which, you know, they are very critical to doing calculations about predicting the properties of real particles, but we don't observe them directly. So what I mean by virtual here is virtual reality for me

things that appear virtual, appear abstract, are just things that are very deep in time, in the structure of the things that we are. So if you think about you as a four billion year old object, the things that are part of you, like your capacity to use language or think abstractly or have mathematics are just very, you know, like deep temporal structures.

That's why they look like they're informational and abstract. is because they're existing in this temporal part of you, but not necessarily spatial part.

There's a couple ideas that are embedded here. So one of them comes again from Paul. He wrote this book years ago about the eerie silence and why we're alone. And he concluded the book with this idea of quintelligence or something, but this idea that really advanced intelligence would basically just
