What is the widely accepted theory about the origin of the universe?

What is the cycle of the universe?

One theory is that our universe constantly recycles itself. Every trillion years, the universe explodes into life, much like the Big Bang, but not just the once. It is a never-ending cycle of rebirth and death. Called the ‘Cyclic Universe theory‘, it could help explain why the universe is not expanding as fast as suggested by the Big Bang theory.
