Poll: The Earth Destroyed by a Black Hole!?!

[wkrepelin]

People seem to be concerned that scientists at the LHC (Large Hadron Collider) on the French/Swiss boarder in Europe might create a black hole here on Earth and destroy the planet by colliding particles together at previously unachieved energies. Do you have concerns about this or even think it's possible? Do you have other concerns about these sorts of high energy experiements?

Let's hear what you've got escapists.

No, any black holes created would be too small to survive for more then a few milliseconds...

Unless we create a Particle accelerator so big that it engulfs the solar system, even then I would have some doubts...

So there's absolutely nothing to worry about, the scientists know what there doing, and my cousin works there...

People are idiots.

The way it was explained to me is that there is more chance of all the molecules in one's body losing cohesion during your morning shave.

There isn't enough mass on earth to create a proper black hole. The problem with people being concerned about it is that they don't really understand what a black hole is. They think if the sun turned into a black hole then the earth would be sucked in, which is completely wrong.

A black hole may have incredible gravitational prowess, but that is because of the immense amount of mass packed into an incredibly tiny package. Gravity is a function of mass and distance. If the sun would become a black hole, Earth's rotation around it would react no differently, because the center of the Earth's mass will still be the same distance away from the center of the Sun's mass. The Sun, of course will be much smaller, and the escape velocity would be greater than the speed of light, which would not allow photons to escape the gravitational sphere.

Ha! silly silly people... the black holes, as said above, would be too small to survive at all.

Although, a cool conspiracy theory would be nice here... I want to read some crazy sh*t here

 

[SomeUnregPunk]

It is not the concern of the rational people but of the irrational media looking for attention.

But if the sun DID become a black hole wouldn't we all freeze to death?

This is like a year late. If anything was going to happen then it would have happened already. They have been colliding for a few months now. A black holes size is inversely proportional to its heat. A black hole created by the LHC would be very tiny. Thus it would burn up quickly.

That is a different matter entirely and not the point. But yes we would, but not starting until 8 minutes after the event.

Eventually. But it wouldn't effect how Earth rotates around the sun. And a black hole created by the Hadron collider wouldn't have enough mass to do anything significant before it's internal forces pushed it apart.

 

[teqrevisited]

Nope. Although if Gordon Freeman works there, we all need to be worried. Will I Am of the Black Eyed Peas in particular.

You've seen that photo ;]? There's someone who bears a strong resemblance to the G-man working there, too.

OT: I'm not concerned about this. If it was really that dangerous would they have built it in the first place? I know we humans don't have a good track record of things like that though *Cough* nukes *Cough*. But it's not as if they got together one day and said "Hey why don't we build a giant black hole generator that could potentially destroy the world? That'll be a laugh."

I'd think it'd take a bit longer, since we have an atmosphere.
Otherwise, we'd freeze to death every night, staring out at the cold, cold stars.

A black hole is a stellar phenomenon that often occurs when a star goes super nova. What happens is the internal forces of pressure and inter-molecular repulsion are overcome by gravity. Thus, the majority of the star is pulled into the center of the former star, and become a black hole. The area of the black hole is theoretically infinitely dense, and any new matter is sucked in and joined to the mass of the black hole.

Because of the amazing density and mass, this creates an incredible gravitational force in the nearby area. A force that can bend light like a lens, or, if the light is close enough to the center of gravity, pull it straight in. But because there is no positive change in mass (no mass gain, because of the Theory of Conservation of Mass) the amount of gravitational force between it and any stationary object does not change, because that would require either a mass change, or a distance change.

MATHS TIME!
Force of Gravity (F) being F=[G(m1)(m2)]/D where G is the gravitational constant, m1 is mass of first object, m2 is mass of second, and D is the square of the distance between them. When D becomes tiny, and mass becomes huge, the force of gravity can even overcome light's velocity and prevent it from leaving.

I just had my physics provincial exam...I DONT WANT ANY MORE DAMMIT!!!
But if there is a black whole, then we all get to shoop-da-whoop!! (which is how I was able to understand electromagnetism)

Well, in a way, every particle with mass is a teeny black hole if you think of it as a single point instead of a "cloud of probability." Any amount of mass condensed to a single point is, effectively, a black hole (infinite density and whatnot). Soooo, even if you could make these particles act more like points and not so much as "clouds of probablity" as they normally act (which is what they think they can do) you wouldn't see much happening. It's not like black holes suck everything into themselves. And it's not like the electrostrongweak force would just be GONE. That thing is turning back into a regular particle forthwith.

Besides, the schwarzchild radius on that thing would be SO TINY (the Earth's is about a centimeter). The chances of even a single atom coming into "contact" with such a black hole in the time that it could exist is, well, equally tiny.

There isn't any way it would be a problem, is what I'm saying.

I rewrote that sentence three times to make sure I got it the way I wanted. That still failed considering all my rough drafts contained the word "starting" and my final draft didn't.

i dont think it matters
if it does creat one that destroyed the planet...whos going to *****?

Haha sorry. I probably should have put a spoiler on it. Physics (which is really just applied mathematics) is one of my hobbies.

 

[Eggsnham]

I remember hearing something before that pretty much proved that idea the fuck wrong. So no, I'm not worried about that.

The very first post in the thread, and already everything has been said. The Pox upon you blasted ninjas, keeping me from showing off what little physics I know

Look, if you want to believe that a black hole could actually be created, wouldn't it be wiser to just kill yourself now? Just sayin', cuz being sucked into a black hole would take almost forever, thanks to that special theory of relativity...
