*bobs his eyebrows in mild surprise* Basically, yeah. Everything gets (*demonstrating with both hands*) squished and strung-out when you're dealing with that much gravitational force. Matter, space, time, photons, all of it. The math (which I don't remember much about, but it's still cool) says that if you could get close, stay just outside the event horizon, and then escape back to normal space? Your clock would read earlier than the clocks outside.
*shrugs and drops his hands back to the task of jelly-ing his bagel* So you could only get to the future, theoretically. No one's figured out how to go backwards. *half-smile* More than you wanted to know?
