Adam Brown: belief

Transcript context

…It's a little bit confusing because in one context, we're laying out very practical—I don't know if you can call black hole batteries practical—but very tangible limitations on the what future, like very distant future descendants, could do with all the matter in the galaxy and so forth. On the other hand, we're like, "Bubble universes as big as our own made somewhere in somebody's lab, maybe." So, basically, how confident are we that the practical limitations we think we know about will actually constrain our future descendants? That's a good question. Certainly, some of the possibilities we've discussed so far have different epistemic statuses about how confident we are or are not. And as we also discussed, some of these bounds are somewhat fragile. Can you communicate faster than the speed of light, for example? Let's just take that as an example bound. We think you can't, according to the laws of science as we understand it. Most physicists would be pretty surprised if it turned out that you could. What is your probability if, like, a million years from now, we are able to communicate faster than light? How surprised are you?…
