: : If I had a "rocketship" that could travel into the speed of light (which is according to Einstein's theory only possible with an object consisting of restmass zero.) and i tried to travel trough the black hole, there would be a couple of problems that would appear. : 1: When i approach the "Event horizon" which is the "point of no return" (Must have a speed fast as light to escape) time would slow down and eventually stop as i "enter" the singularity. : (the time dilation only appears to the observer on the outside) : 2:Maybe I wont notice any slowdown of time at all,but i will be as said by S.Hawking "spagettified" and crushed into a spaceless point under an enormous heat. : And the only physical proofs of my existence would be radiation and heat..."Now that doesen't sound good!" : Im sure there is more problems and paradoxes connected to timetraveling than i know about so please mail. :
