First, remove DEI. There is no trust when ideology replaces science.

In my opinion, Einstein is correct, GR is correct, singularities do exist, information paradox problem can be solved by understanding the heart of the thing: the singularity. And yes, I believe Einstein is right, his math is right, and information is preserved by going through the singularity to somewhere else. I know that you guys doing like it because it deals with infinities, but nature doesn't care about what makes sense for us or not.

I think that one big misconception from human expertise and understanding of nature is that infinity doesn't exist. I think that they do exist, and the universe is not bound to our ignorance, or our lack of brain power. GR is correct and yes there's a singularly at the heart of BHs. There's a infinity flow going to infinity as well as our own Universe extends to infinity. there's infinity going on everywhere. in fact, there's no such a thing as finite reality. The only thing that's seems to be finite is our time here as individual living creatures.

Penrose talks about a cyclical Universe which seems feasible to be. We all know what Dark Energy is going to cause eventually, probably. It would maybe cause the slowest state of entropy possible. Do you know what I Mean? it can answer the question at the end of the EP I think.

I love neutrinos and how weird they can be. One of the tasty mysteries we are yet to figure out.
