#468 – Janna Levin: Black Holes, Wormholes, Aliens, Paradoxes & Extra Dimensions

Because if you start to say... One of the aspirations was, in the same way that we identified the law of electroweak theory of... matter, that it was a single description and exactly landed on the description that matched observations. People were hoping the same thing would happen for a kind of theory that also incorporated gravity.

There would be this one beautiful law, but instead they got a proliferation, all of which did okay or did equally badly. They suddenly had trouble finding, not only finding a single one, but sort of That would just beg a new question, which is, well, why that one? And if nature can do something, won't she do anything she can try?

And so maybe we really are just one example in an infinite sea of possible universes with slightly different laws of physics. So if I can do some of these things on paper, like imagine a higher dimensional space in which I'm confined to a brain and there's another brain or maybe a whole array of them, maybe nature's tried that out somewhere. Maybe that's been tried out here.

And then, yes, is it possible that there's life and civilizations on those other brains? Yeah, but we can't communicate with them. They'd be like in a shadow space.

No, that's fair. I'm limited in my communication because I'm glued to the brain, but some things can move. We call the bulk through the bulk. Gravity, for instance, a gravitational wave. So I could design a gravitational communicator, communication system, and I could send gravitational waves through the bulk. And how SETI is doing with light into space, I could send signals into the bulk.

Very expensive. Very hard to localize. They tend to be long wavelength and very hard to do. A lot of energy moving around. A lot of energy.

It is possible that there's other things that live in the bulk. I mean, last night I was calculating away, looking at something that lives in the bulk.
