I have a little doubt
Hey guys, I'm bread 🍞 I have a little doubt. And please correct me if I'm wrong. What if the universe is like a yo-yo. I mean we know big bang happened so after that explosion or something else universe kept expanding. But what if after certain billions of more years later the speed starts to deplet very slowly and more years later it gets reversed causing the universe to contract. Many galaxies collide etc. And when the universe is at the brink of being shrink into nothingness it explodes or expands again. I'm sorry I don't know much about quantum mechanics and physics so it could be wrong. Sorry for wasting your time
