I ask questoins to which I want answers. If I ask a question I don't care it it's worth asking, and I don't care if i don't like the answer as long as it's reasonable. I just want to know why things happen.
Okay everybody I was wrong... I forgot that Einstein wrote a paper that said light was exactly the same speed as gravity, no more, no less. What I was reffering to was Newtonians gravitatonial thingy that stated that gravity was indeed faster thant the speed of light. But what I had forgot about...
<Q>Since gravity travels at the speed of light, if the moon were instantly zapped, its gravitational effect on us would disappear at the same time as its image.<q/> I didn't say that. I said gravity was instantanous, in theory, and light was slower, light bends to gravity.
<B>If<B/> I am correct in saying that light travels at 650,000,000 mi/hr. and considering how far the moon is. Say that the moon effects our waters with an almost instantaneous field of gravity. Light travels in waves so if the moon was suddenly zapped away out of existence the light the sun...
Well think about this scenario. What if you are out on a nice lake in the middle of the night with a nice full moon lighting up the night. Then out of nowhere an alian ship decides to play a prank and zap the moon from the sky. Wouldn't the water recede from it's tide about 2 3/4 seconds before...
