The Big Rip Theory is where the universe matter and space-time itself is being gradually ripped apart as the Universe expands in some time in the future, until there is an infinite distance between particles.
Cosmology 🌌
In the big bounce theory, the universe repeatedly expands and contracts into a new "big bang", seesawing back and forth in a massively big-picture timeline.
Cosmology 🌌
The Big Crunch is a hypothetical scenario for the end of the Universe, in which the expansion of the Universe eventually reverses, and the Universe recollapses on itself.
Cosmology 🌌
The JWST data suggests galaxies are formed faster than we thought, but it does not mean that they necessarily contain elements that predate the Big Bang, or that our universe is not expanding.
