Doom's Day machine?

Today everybody has been talking about this machine that is supposed to bring about the end of the world.

I'm not saying that it's a silly suggestion, I just don't think that anything man can build would bring about the destruction of an entire planet. I mean we don't even have the technology to stop a comet bigger than three miles wide, so how are they gonna build a device capable of destroying an entire planet?

Some people have suggested that it will create "mini black holes" that will join into one big black hole and suck us all in. Yeah right, no one even knows what a black hole is, let alone how to even accidentally make one.

I don't really think that it would be used as a weapon, I mean when there is talk about even a nuclear weapon the world is quick to condemn any such action, so I doubt that any country would allow the testing of such a weapon that would end the world.

The world may be ended by man, but it will be over a course of time, not some crazed scientist and a big bomb that will wipe us out in the blink of an eye-- that idea is, in my opinion, STUPID!!
