You can see the singularity around a 'black hole' so we do have a reason to believe they exist. The rest is all speculation. I do agree that you probably have to be traveling the speed of light to escape a black hole, but hey, we've been wrong before

Edited by The Cellar Door: 4/22/2015 4:55:26 AMI think you have you're terms mixed up, and misunderstood what I said. Black holes [i]are real.[/i] But they aren't actually holes that lead into a different dimension, or whatever the SciFi channel will have most people believe. They are points in space time that are so dense that nothing can directly escape, not even light. They don't lead anywhere. They're just there. Like planet Earth, if you kept flinging shit into it, it wouldn't go anywhere, it would just stay on Earth, kind of like that, but in a much more extreme, much more changing-of-the-shit's-fundamental-properties kind of way, the kind of way that the shit can't get off of it, no matter how hard it tries, even if it's traveling at the speed of light. And it is theorized that eventually the shit will be given off as radiation, this shit radiation is called Hawking Radiation, however, this radiation is [i]not[/i] the same shit. Simply different.

Ahh yes, Worm hole was the term I was looking for. Black holes result from a massive star dying, right?
