Thanks. Yeah, I just picked up the concepts over time. I'm no good at math, but the abstract understanding of it I can get. The best way to get to understand it, at least this concept, is have someone stand on a trampoline and roll a ball around them.  Then switch them out with say a child, you'll notice the ball is less affected by the child than the adult. That's basically what gravity, and Einsteins's equation explains. The heavier the gravity, the more it has an effect on things around it.
