Part 6/8:
Cyclic Universe Theories suggest a "Big Bounce," where gravitational forces draw the universe back into a collapse, only to expand again. Although initially believed infeasible due to insufficient matter, further theories involve higher-dimensional spaces, where collisions create cycles of creation and rebirth.
Conformal Cyclic Cosmology posits that every end of cosmic expansion could represent the birth of a new universe, performing a cyclical transition akin to the Big Bang.
Quantum Interpretations explore how fundamental particles could spontaneously generate new universes through quantum fluctuations, transitioning the dialogue from deterministic cosmology to one proposing randomness and uncertainty.
