Ekpyrotic Universe Theory
The Ekpyrotic Universe Theory suggests that, unlike the Big Bang that began from singularity, our universe is one of a pair of universes that collided. It is an alternative to the widely accepted Big Bang theory . This collision resets the universe. From there, it expands for billions of light year until it contracts back to the Big Crunch . The speed and energy of that reduction creates another massive collision and the universe is reborn. and this continues for infinity. And the Mind-Blowing Fact is that if the ekpyrotic scenario is correct, our twin universe is right next to us in another dimension, separated by a distance less than the diameter of an atom. That’s close, even for siblings!
