: : : Why do I keep hearing that there is no speed faster than light. How is anyone positive about that. If there is such a speed that is faster, isn't it possible to pass through the horizon of the hole, and come back out without being ripped into pieces? Also, I heard that once you pass through the horizon (supposing that a person did somehow), that death would be inescapable because of singularity, and something about how a person couldn't escape their own future. How can a person's future lie within the black hole, and if it is, could it be the key to time-travel, or maybe a fountaion of youth? just curious.

: for years everybody thought speed of sound was impossible to exceed but chuck yeager changed that ! ....eventually speed of light will be exceeded also....probably already being done by extraterrestrials

Fellows, there are some major differences between sound and light. Sound is a mechanical waves that travels through a medium. Light is an electromagnetic wave that travels through no particular medium except the spacetime continuum. As soild creatures, we can mechanically change our speed without causing unusual changes in ourselves or our environment. We cannoit do this at the speed of light, because we are not electromagnetic in our present form. Become pure energy, and you too can travel at the speed of light. Stay soild and human, and you're sunk.
