Hi, I'm Jadaav and I'm only 14 years and I wanted to know which topic I need to learn first and so on about the creation of the universe. I only know that the the universe was created by the big bang and inflation followed and then the universe is continuously expanding due to dark matter which scientist have suggested. I saw these on a documentary. I only know these in brief I don't know very much of them, so I wanted to learn each of them. What do i need to learn? Answer please. I'm totally confused. It's my first start.
