OT: Study Reveals Flaw in Black-Hole Theory

Baron, they all lie. NBC has been caught and so has CBS, CNN, and ABC. ALL news organizations lie, they also make mistakes, and from time to time they have even made some huge *** whoopers and been called to carpet for them. Enough please. This is a free nation, if you don't like Fox, don't watch. Most of us are adult enough to make decisions for ourselves and are quite good at faretting out BS from fact. I myself won't watch NBC news at all. I prefer ABC and Fox, but mostly ABC.

Back on Topic:
So what would happen if a Black hole, say a very small one about the size of a pin head, came into contact with our planet?

The difference is that when other news organizations are caught reporting falsehoods, they at least have the decency to put out corrections. Fox makes a habit of ignoring any mistakes in their reporting. In that, they act more like a propaganda machine than an institution with any journalistic integrity.

As for the black hole... that depends. Are you saying the size of a pin head is the size of the event horizon, or the volume containing all the mass? If the former, it would almost certainly evaporate due to Hawking radiation. If the latter, depends on the starting mass, but it probably would also evaporate.

If a black hole were somehow created on the surface of Earth, it wouldn't last long. If it was created on Earth, then by definition it would need to have a mass much less than that of Earth, and so it will have a gravitic pull much less than that of Earth. If it doesn't have the dominant force, it will not consume much mass, and will evaporate.

If the black hole came from outside the solar system, then depending on the mass, and how close it passes by, it could either knock us into a different orbit, or take out a chunk of the planet approximately the size of the event horizon. Then it would continue to bypass us and either get caught up in the sun or exit the solar system.

Does this mean Black holes can travel thru space like a comet?

[Phoenix-D]

Anything can travel through space like a comet, given the right orbit.

Mind, if a black hole or star does that, its likely to get a bit hairy on any planets in the same system..

Yes. As do all solar bodies, including our sun. Our galaxy, like most galaxies, is in a constant state of motion. The solar bodies within it are also moving about. Galaxies within the universe are all moving about and colliding, mingling, and uniting also.

The unviverse is not static. It is in constant motion that is most noticable over millions of years; just as evolution of species on Earth is observed.

Colliding, not really. More merging. I read somewhere (not sure where) that when the Milky Way and Andromeda galaxies merge, there should be something like 4 actual collisions between stellar objects After all, galaxies are mostly just space, which is just...space.

Strangely enough, people are mostly empty space to.

[GuyOfDoom]

If you goto the atomic scale, then yes most everything is empty space.

I always found it interesting that there is an 'infinite' amount of space between any 2 particles. .01m,.001,.0000001,.0000000000000000000001 and so on
