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. |
