I sort of understand Einstein's theory of relativity. I'm trying to visualize what the universe would be like if the speed of light were added on to moving objects. objects are moving in so many directions that it's hard to understand how one would even add the speed of light on to a motion. for example, our galaxy is moving in a direction, our sun is moving around the galaxy's center, and we're moving around the sun and moving around our earth's axis. i suppose if visual light were added on to movement it might just be too confusing, but i cannot exactly imagine how.
