Yep, bigtime interested. I studied a bit of it in college.
As for time, it apparently began when the universe began. It's considered a dimension for mathematical purposes, and Stephen Hawking's theory on it is that unlike the 3 spatial dimensions, where you can travel either way in each dimension, you can only travel one way in time, i.e. forward.
If you're really interested in physics, check out string theory
