I am interested in learning all the different "laws" and "theories of laws" related to Physics. I do realize that I could take a class or purchase a book but however I would rather use the knowledge of the EVC forum to learn about Physics. I would like to start with "understanding gravity" to be able to apply it to other ideas such as the Big Bang model.
I know there are a number of people on the boards with substantial physics knowledge but I'm not sure that a thread such as the one you propose will work as it stands.
A better approach might be to formulate a clearer question relating to the role of gravity in the big bang and from that develop a dialogue which will increase your understanding.
