It's called cyclic conformal cosmology or something like that! And it's very neat to think about.
The end state of the universe after everything degenerates to just EM radiation (this is well after red dwarfs go supernova and protons spontaneously degenerate) looks similar to the universe pre-big bang. If everything is just composed of stuff that moves at the speed of light then time and distance lose all meaning. An entire 15 billion light year across patch of space is exactly the same as one crunched into the width of an atom from the point of view of completely degenerated em radiation. The "next" universe could then start from the end of ours.
Penrose is the guy who theorized this first - although the idea of a cyclical universe with long periods of repetition is at least as old as Hinduism - and he claimed some empiracal data to back up his theory.
What does that mean for us practically? Essentially nothing, lol, although it is possible for intelligent beings to encode a message for the next universe via radiation so I guess we could check our universe's answering machine.
"believe it or not, the matter's not home, leave a message after the tone"
Here's a counterpoint by another astrophysicist who writes for Forbes on why no such evidence exists yet, contrary to Penrose's statements. archive link
Doing just fine, thanks for remembering. Shit was really mild and everything's back to normal now, nobody else caught it. You doing good?
Funny thing is, the biggest lingering effect actually isn't physical at all, instead I'm suddenly aware of how shitty my job is for my mental health after having such a long break. Gotta direct this into some kind of change.
My shower thoughts confirming I am just as smart as most scientists
Does he have a paper or is this more like, I have a nobel prize now, you have to listen to my pet idea?
Not that I think he's wrong. Einstein-Cartan (and it's expanded version) have been very interesting for a long time. In that theory, forming a black hole twists a tensor that, instead of creating a singularity, pops a new universe into place with the mass of the black hole fueling it's expansion. I just wonder what his mechanism is.
The big bang theory, such as it is, is just anthropocentric drivel by scientists quaking in their boots at the thought of leaving christian dogma behind. It's a biased, desperate jump toward anything that seems to have a finite beginning so you can say "hey, he did it, that's when god turned on the lights". At least, that's how I see the move from steady state cosmology to the current circlejerk.
Yes, it is discussed in this article. He talks about conformal cyclic cosmology which I think is also what's discussed in the OP.
