Since we are on the topic of special relativity... and since you guys sounds like Astrophysicist(I hoped I spelt that right!).....
I did "attempt" to understand Special Relativity, and my understanding so far is that the faster you travel, (rather the closer to the speed of light you get..) three things will occur, 1) Time Dilation, 2) Length Contraction, 3) Mass increases.... I am not 100% sure about the last one. But these changes are only apparent from the frame of reference of the stationary observer. if you were the traveller you would not noticed the change. Until its too late ... gasp!
According to some article I read... General Relativity is just Special relativity taking in consideration of gravity. Is this true?
But at this stage I fail to see how SR is in anyway related to bending space time.... ??!?
On another note - special relativity in terms of Black Holes, my understanding is that if you reach the singularity of the black hole you are travelling at the speed of light is this correct?
as even light cannot escape from the singularity of the black hole. Hence is it safe to assume to reach singuarity you would have to be travelling at the speed of light?
and from the the observers point of view, you would be experience the 3 SR things above?
So you would never really approach it from an observers frame of reference, (you'd get very close, but never to really reach it) since time would come close to almost a standstill (not quite but almost) in itself. Is this true?
