there are so many interpretations to our universe
1.many world theory : universe divides in to many worlds according to the possibilities of a particular event. Lets say you woke up today at 7.00am in the morning.so there will be another world where you wake up at 7.01 and another 7.02 just like that infinitely many possibilities.
2.universe is a hologram: this concept states that the light travels in a loop across the edge of the universe just like in a torus.so its finite and there's is nothing beyond.
3.string theory : everything we see including (planets and moons)are vibrating in different frequencies according to the frequency we identify each from one another .lets say a car which is visible to all of us may become something entirely different if it vibrates in a different frequency
