That path requires far more science and technological advancements than expansion, which is why I believe expansion would happen first. I don't see why both couldn't be done, but the trancension hypothesis relies on a lot of extremely complex energy manipulations and things that aren't even provable right now. We're talking about "living inside of a black hole" or "living in a parallel dimension", or "living in a simulation", right? (Can't watch the video right now cause I'm at work, but I've read about trancension before) That to me seems less likely than simply moving our stuff and people to other rocks around our star, and eventually another star.

And as I stated in that last thread, I don't believe that this is the answer to the fermi paradox of why we haven't heard from other intelligent life. There are plenty of reasons we may not have heard from them. Number 1, we aren't listening or looking for the right signals and may not even be able to comprehend how other intelligent species communicate. Number 2, they might be purposefully ignoring us until we're actually out in space exploring ourselves and worth talking to.
