actually this whole day arguments simply depends on whether or not you are talking about a sidereal day or a solar day...basically whether you define a day as 24 hours, or define it as the time it takes for the earth to make one rotation...obviously the correct way to define this would one rotation, in which case if everything slowed down a day would be longer from an observer outside the universe, but the same to us.

As for all this stuff about time travel--backwards time travel is not possible at all...forward time travel is not exactly possible, just living longer. Also, I don't care what cnn.com says, sound can not escape from the singularity of a black hole. black holes do emit some matter, and that matter could produce sound. And as for the pain question, i'm not really sure. I would think not, because our nerves don't relay information to our brain faster than the speed of light, and if light can't escpape, then neither could our nerve "transmissions".

None of this had to do with the original post, but neither have the last 3 pages, so i don't feel too bad.
