Yea, people are worried about mini-black holes and crap. Even though they do have a chance of being created, these mini-black holes are almost microscopic... so there is nothing to worry about.
|
But the thing about a black hole of any size, their event horizon expands as it consumes matter (which adds mass to it causing the gravitational expansion). Eventually it would consume our entire planet, but I don't know how long that would take.
|
Depends on the size of the black hole. I once heard that if you have a black hole the size of a proton, it can only consume something the size of a proton or smaller, and if the object is the same size as the black hole, the object has to hit the black hole *just* right to go in. And for each particle it swallows, it grows only slightly, so it could take it a while to get big enough to even be seen by the human eye.

The hole would grow exponentially, it would take awhile, but it would get going eventually.[/quote]

Im quite sure you would be able to see the black hole, if it was on earth, as a black hole wouldnt emit any EM radiation from the light section of the spectrum, therefore it would appear black in broad daylight.
|
LOL, you couldn't see it, but you could see the deformation of everyone else as it bent light.

I don't see what logic people have that this will even create a "mini" black hole.
|
I don't see the logic against it.

These collisions happen everyday at much higher energies and we're fine. Black holes are created in much different circumstances.
|
Ah, well if that's true then alright. I haven't had much physics; I assume this would be physics wouldn't it?

The event horizon is the level from the singularity where light cannot escape. Past the event horizon, the escape velocity is faster than the speed of light so escape is impossible.
A black hole is pretty much a planet a mile or so across. It has the same gravity as the star that gave birth to it. If you could stand on the surface of a star you'd feel the same gravity as if you were standing the same distance away from a black hole.
So since a black hole is only a mile across, and a star is lets say 10,000 miles. If you stood 9,999 miles away from the black hole you will feel the same gravity as if you were standing on the star. Not the whole star as it blasts off the outer layers in the supernova.
If you fell into a black hole, and somehow stayed in one piece. You wouldn't go down a "funnel" you would just hit a planet. If you could look at the sky, you would see just see blinding light.

In theory gravity also effects the flow of time, it slows it down as it gets stronger, if that is correct, and you did manage to stand inside the black hole on the surface of the ex-object, you would probably get a pretty good show of white and then the sky would go black, as the universe came to an end, due to you being in such a slow warp of time.
