Now somewhat near the end of Hyperspace, It spoke of blackholes and how light can't escape. Doesn't that mean that if we wanted to use blackholes for transportation then we would have to go faster than the speed of light? Which I've read many times is impossible because you would obtain infinite mass. I had a strange thought to, In Hyperspace it said to imagine a subway train that would go near the speed of light, it would get squished up and distorted and then expand to fill up the station when stopped. Doesn't Time Slow down when you go that fast? So say you take a 2 minute train ride, wouldnt that be alot longer off of the train?
