If the Universe Repeats, What Created the First One? - The Universe & Space

In the profound silence of modern cosmology, we are faced with a paradox that challenges our very understanding of linear time. If we live in a cyclic reality—a "Big Bounce" where every end is merely a new beginning—then we must ask: If the Universe Repeats, what was the catalyst that set the very first expansion into motion? We are accustomed to a world of cause and effect, where every action has a predecessor, yet the idea of a repeating cosmos forces us to confront the "unmoved mover," a singular event that existed before the cycle itself was established.

The concept of a recurring reality suggests that our current Big Bang was not a unique moment of creation, but rather the latest pulse in an eternal heartbeat. However, If the Universe Repeats, logic dictates that there may have been a "First Universe"—a primordial state where entropy was at its absolute minimum and the laws of physics were forged for the very first time. Some theoretical physicists suggest that the cycle has no beginning, existing as an infinite loop of time, while others propose that a quantum fluctuation in a higher-dimensional "bulk" might have served as the ultimate origin.
