There are hundreds of theories on every subject of physics, much more than could be covered in even a few years time. But, if you're really interested in learning more about physics, this forum is great place to start. There are lots of ideas and answers. a good physics book for you, if you're interested, is Stephen Hawking's book A Brief History of Time. It gives a general layout of physics and spacee-time. You'd find it really interesting. I did when I first read it.

: Hey people. I am only fifteen, but I am extremely fascinated by this topic and ones similar to it. Can somebody fill me in on what we are talking about, because, as you can all see, there are fifty million posts to read here. So please, get me started somewhere efficient....and be patient. Thanks friends. : Peace.
