You've been given a taste of what to expect if and when you come back. Just to give you a bit more to ponder, consider what is, and is not, a scientific theory. Everybody has a theory (small t). A Theory is different. It must make falsiable predictions, and make them correctly. It's not just an ad hoc collection of guesses that feel good to you.

I have a theory that everything is due to the action of nano-gnomes. NGs are omnipresent, omnipotent and omniscient. They are invisible, but they make the universe work.

Prove me wrong.
