The Black Holes-Thread

[Centurio Nixalsverdrus]

Today I learned from a short video with famous German tv-physicist Prof. Harald Lesch that a black hole is indeed not a hole, but a body / corpus actually!

• It is a very very big star, at least three times a big as the sun, that collided because the thermic pressure inside ceased.
• The mass gets compressed to such a density, that the sun would end up with a diameter of 3 km only.
• And because of its gigantic density, the escape-velocity (sorry a direct translation) is bigger than the velocity of the light. Its gravitation is so gigantic that it catches every light falling upon it, so that we actually cannot see it.
• What leads us to the conclusion, that a black hole is indeed not black, but invisible.
• Its mass is so big that it disrupts the space/time continuum and thus, there is no time at all inside it. Why?
• And because there is no time inside, there is no perception, and no information could ever reach us from the inside.
• Dying from a black hole means you just get attracted by that corpus, and because of its incredibly gravitation, you get immediately squashed to the size of nano-pieces on its surface.

So if I understood that right, it is not black, and not a hole at all. Why is it called a black hole then, instead of invisible corpus? And please tell me if I understood that correctly, or what I got wrong. This is very complicated for a formula-hater like me.

So why is there no time inside it? and,

Could small black holes, like the ones possibly created in CERN, kill me? For example, if such a mini black hole would be flying around invisibly, and it would be accidentally flying through me, would I die? Would I get sucked in?

I know that some of my questions might be stupid, but I really don't know it better.
