Welcome to Physics Forums Amir!

Have you had a look round the rest of Physics Forums? Not only the Physics sub-forums, but also the Astronomy and Cosmology ones?

Some people like to test their understanding of physics by trying to understand some of the more credible ideas posted here in Theory Development. IMHO, there are some quite interesting posts in this sub-forum.
