Hi everybody, I have a high school physics project in a few months and I need your help. As you can see from this post's title, its about Theories of the origins of the universe. I've read Hawking's "Brief history of time" and I did some research on Internet but I only found famous Big Bang Theory. Could you please write here other theories and big bang theory - sub theories (With references on the Internet from where I can learn about these theories in detail) because I was thinking that my (Presentation and Papers(15-20 pages)) looks like this: 0. Intro 1. Theory 1 ( About theory, History, notable People, Problems with it ) or ( All this fitting in a nice chronological story ) 1.1 (If it Exists) Sub-Theory ( Same here ) 1.2 (...) 2. Theory 2 (...) 2.1 (...) ..... 3. (Highlight) Big Bang Theory () 3.1 Inflation theory (? Does this go here ?) 3.2 Multiverse theory (? Does this go here ?) 3.3 (...) 4. Should I explain here formation of the universe that we see now - starting from singularity to possible fate of the universe ( Big Crunch etc.) (Shortened) ? 5. My Conclusion I will not be doing equations or graduate level stuff , I just need to explain concepts and how physicists came to certain understanding. I will be presenting this for max. 20 minutes. Thanks in Advance.
