The "Cyclic Universe" is a cosmological model suggesting that the universe undergoes infinite cycles of expansion and contraction. In this theory, after a period of expansion, the universe eventually reaches a maximum size and then begins to collapse back into a singularity, leading to a new Big Bang. This process repeats indefinitely, creating a series of universes that are born, evolve, and die. This concept contrasts with the traditional view of a linear universe that began with a single Big Bang and will either expand forever or end in a singular fate. The idea of a cyclic universe has been explored by various scientists, including Stephen Hawking and Roger Penrose, who have proposed different mechanisms for how these cycles might occur.
