So the time is slowlier around BH., Lats assume I am hanging around one BH (with a girl and stuff of course), and 2 light years away, another BH with another guy (he is single but trying).

Our time is twice slowlier then without BH around. So I send him a light signal. It will travel 2 years, but for us it would be 1 year.


So for us we exchanged information faster then speed of light??.

Ok, don't laugh, I know it's a weird question. I want my friend to do something for me, when I asked him I said "how many prettys do I have to put before please to get you to say 'yes'?" His answer, "pretty close to infinity". So my question for you is, how would I mathmatically express infinite prettys. I know what the symbol of infinity is, I just want a intellengently clever counter to his response. He's about as close to a math geek as you can get with out actually being one (he's an comp. sci/ engineering major), so extra points for a really cool expression.

just by going by this one "fact", we just MUST be wrong.
We are all in agreement that light can't escape black holes? Ok, that's the fact. since light is effected by gravity, how do the observations we've made on our planet have any merit to the true speed of light? we are in a giant galaxy containing billions of stars like our sun. if the sun's gravitational force effects the earth so much as to whip us around it, then we must be feeling the gravity of the sun but we just don't realize it. all we really feel is the gravity of the earth. we see things fall, not shoot toward the sun. but nevertheless, it's there, and that means that it's also effecting the light we see. the speed of light that we calculate within the gravitational feild of the sun, and the other planets and the rest of the milkyway is thus only relative to this system we are in. if we go to perhaps a region of space where there are no stars, the speed of light could be a lot faster because it's not in a gravit
