Answer:the Big Bang theory
Since the early part of the 1900s, one explanation of the origin and fate of the universe, the Big Bang theory, has dominated the discussion. Proponents of the Big Bang maintain that, between 13 billion and 15 billion years ago, all the matter and energy in the known cosmos was crammed into a tiny, compact point.
I’m pretty sure it’s the Big Bang theory I learned this in like middle school lol
