So I was watching the Discovery Channel or Nat Geo or some such cable learning station. I wish I'd DVR'd it. Anyway the topic was Einstein's theory of relativity (E=MC2).
I'd watched many shows dealing with this topic of the theory of relativity. Now, I've always had trouble with spatial comprehension, and I'd watch these programs and come away frutstrated. I felt that the plain practical meaning was just out of my mental grasp.
The punch line was helpful: space-time tells matter-energy where to GO, and matter-energy tells space-time how to LOOK. Oh, and that time-space are bound together like a piece of fabric, with objects 'curving' or 'bending' the fabric, which explains gravity. You can click here to see a brief video of this. Matter and energy are bound together as well and are interchangeable when accelerated to the speed of light.
