Whew, that is so deep. So two marbles a billion miles away from each other in space, given that nothing else is between them, will attract due to gravity and begin falling toward each other. I get it.<br /><br />Gravity, I guess travels at the speed of light or faster? If they simply popped into existence then it would take some time for gravity to arrive between them. Gravity seems like magnetism. Their masses must have charge relative to each other.<br /><br />I'm still wondering if a wave of light is caused by the wake of a fast moving particle, and what would it be reacting to. Suppose a particle was traveling faster than the speed of light (in a vacuum if you must). Wouldn't a wake cause a burst wave when it exceeded the speed of light? Just wondering. <div class="Discussion_UserSignature"> <p>DenniSys.com</p> </div>
