Re: OT: Study Reveals Flaw in Black-Hole Theory

I just don't understand the need, even if you agree that they all 'misrepresent'/skew the truth, to keep pushing that somehow Fox News is worse. that the company line?

Re: OT: Study Reveals Flaw in Black-Hole Theory

As for black holes...

"Keeton, a member of Rutgers' department of physics and astronomy, said it couldn't happen. He told The Chronicle that a tiny black hole probably could suck up only a few atoms at a time.

Yet it might not go unnoticed. If a black hole as massive as an asteroid -- thousands of tons -- passes through a room, there would be a subtle gravitational tug. "

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.

Can you give a reference to a case where any other major news network than Fox (ABC, CBS, NBC, CNN, MSNBC, etc.) tried to represent a politician caught in a scandal as belonging to a different party? And then refused to acknowledge the "mistake" when caught?

Can you give a reference to a case where any other major news network than Fox (ABC, CBS, NBC, CNN, MSNBC, etc.) made an unfounded claim that a major 'rising star' politician had some sort of radical (not even necessarily 'terrorist') training/indoctrination in his background? And then refused to acknowledge the "mistake" when caught?

Re: OT: Study Reveals Flaw in Black-Hole Theory

FNC did do a pseudo retraction, which should have been an apology for bad journalism.

What is interesting is the claim is based off of the Washington Times. It looks like the show that it occurred on it like a Good Morning America or something, I haven't seen it.

But this is a thread about black holes...

What exactly is nothing? Is energy something? I'd imagine that matter is broken down as much as possible by the gravity. Perhaps to the most fundamental state/particle.

Re: OT: Study Reveals Flaw in Black-Hole Theory

More important than size, is mass.

A hole with an event horizon with radius 0.1mm would be 1% of Earth's mass.
That would be a pretty noticable gravitational pull.

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

Re: OT: Study Reveals Flaw in Black-Hole Theory

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..
