blackholes dont necessarily suck up everything, but it pulls things with an incredibly strong gravitational pull, not even light can escape its pull, thats why its dangerous

if we were to create one, and if it was to get out of control. Would hl2's grav gun be helpful?>. I'm just interested

heh, noe.
first of all, its fiction.
secondly, its not stong enough.
thirdly, you wouldn't be able to see it before you got pwned.
fourth(ly?), you wouldn't be strong enough to pull the trigger.
fifth and lastly, it would break way before you knew it.

The smaller a black hole is, the faster its evaporation rate is. This means that if we were to create any sort of black hole on earth, it would be too small to be self sustaining. It would exist for an instant then simply pop.

I don't know how much needs to be packed, since I don't study this, but it's probably something like taking 1/16 of the whole Earth and packing it inside a pea in order to make a blackhole strong enough to devour the Earth.
Brb, waiting for scientists to take THAT much material for a project.

Srsly, no one's going to go: ohey, let's take all our nuclear fuel and pack it into one bomb and see how big we can make it. Yeah awesome, lol.

Pro scientists are not retards. They're not going to do such a thing. Science is not your enemy.

Just wondering...whats inside a blackhole

As far as I know, noone knows. materia.

i think it's just damn tightly squished materia :/

But if I think about it, even if it is docile, and only sound can not escape from it, then it is still sucking up the particles around it.

Never said about a parallel world travelling, I was talking about the Theory of Relativity.
