I had an interesting thought about what gravity really is, and I had to ask someone to see if they would get the same spark. I have been reading "E=mc^2" by David Bodanis, and after I had read a part about how the space-time continuum flexes around a star in the sky, I had this Idea that maybe gravity is a force created from the warped space time continuum. I pictured how the space time continuum curves around our earth for example, then someone is walking along the earth, but what holds him down to the earth, is the warped space-time. Being that time would move slightly faster where his head is than where his feet are, he is forced to stay on the ground. I think you could compare the warped space-time continuum, to rubber bands being stretched around the earth. I wish I could even understand this idea more fully. It's hard to explain exactly what is in my mind.
