If they are smart enough to know exactly what to do do create a black hole that will destroy everything, they are smart enough not to build it, so this will not kill us all.

I nearly fell for those flashing red lights

How are we going to die if this black hole is created? I cannot imagine this.

How long will it take after the creation until the earth is swallowed? Will we get sucked into that hole? Is it going to hurt? Really this interests me!

[Carlos Matthews]

Thats a point, would it hurt or would it happen too quick to notice?

[Megas Methuselah]

What happens in a black hole anyways?

[Conqueror]

I'm no physicist, but the basic "doomsday" scenario seems to work like this: A micro black hole created in a collider, assuming that it doesn't vaporize by the theoretical Hawking radiation, would have low velocity and be caught in the Earth's gravity field. It would then fall into the center of the planet, where it would slowly accrete until eventually the whole Earth collapses into it. It could take years for the black hole to grow large enough for this, but nothing could be done about it.

Nobody really knows how long it would take for a black hole to swallow the Earth because, according to everything we know about black holes, they just don't work that way. To assume the premise that a micro-black hole created at CERN would not evaporate and instead would suck up the Earth already flies in the face of modern science, so from that point on it's all pretty much speculation.

As for what happens inside a black hole; it's a good question, but I'm afraid it's one of those great unanswerable ones, like "What was around before the Big Bang?" It's not unreasonable to think there might be something interesting going on inside the event horizon, but unfortunately since it's a physical impossibility to transmit information out from within the event horizon we can never do anything more than speculate.
