Uh...there can't be a black hole on Earth


Or anywhere remotely near Earth, considering it would just suck up Earth and the entire solar system.

What a terrible idea for a movie.

I don't know the science of black holes so I don't know if the sun becoming a black hole would have a gravitational effect or not, but all life on earth would end because the planet would become a frozen ball of ice.

You got it right!

Sucked into a microscopic black hole

You will need: a microscopic black hole.

Note that black holes are not eternal, they evaporate due to Hawking radiation. For your average black hole this takes an unimaginable amount of time, but for really small ones it could happen almost instantaneously, as evaporation time is dependent on mass. Therefore your microscopic black hole must have greater than a certain threshold mass, roughly equal to the mass of Mount Everest.

Creating a microscopic black hole is tricky, since one needs a reasonable amount of neutronium, but may possibly be achievable by jamming large numbers of atomic nuclei together until they stick. This is left as an exercise to the reader.

Method: simply place your black hole on the surface of the Earth and wait. Black holes are of such high density that they pass through ordinary matter like a stone through the air. The black hole will plummet through the ground, eating its way to the centre of the Earth and all the way through to the other side: then, it'll oscillate back, over and over like a matter-absorbing pendulum. Eventually it will come to rest at the core, having absorbed enough matter to slow it down. Then you just need to wait, while it sits and consumes matter until the whole Earth is gone.

Earth's final resting place: a singularity with a radius of about nine millimetres, which will then proceed to happily orbit the Sun as normal.

Feasibility rating: 3/10. Highly, highly unlikely. But not impossible.

This is foolish. Everyone KNOWS the universe is only 6000 years old!


Excuse me. I have to go in the closet and pray now.

Correct me if I'm wrong, but I thought all singularities, or actual black holes themselves, not including the event horizon, are geometric points, i.e. they do not have a length, width, nor depth. I'm talking about the black hole itself, and not the diameter of the event horizon. This is what confuses me about the term "small," "smaller," and "microscopic" when applied to black holes, since I assumed that, technically, by the standards of our first three dimensions, they are all equal in size. So, more appropriate terms would be "less massive," "of very small mass," and "of infinitesimal mass." Then, of course, those are still relative terms.

May I be so bold as to say that I think a lot of people who haven't bothered to begin learning about astronomy, let alone astrophysics, string theory, quantum physics, or braneworld theory, would automatically scoff at the ideas of black holes, the big bang theory, the universe originating from a single point, etc., since those ideas are entirely outside the realm of their normal four-dimensional experiences here on Earth. Trying to explain an object of zero volume and infinite density or gravity bending light and time in layman's terms is an act of futility. Even the physicists themselves can only describe these things with equations. How do explain color to a blind man, especially when the blind man doesn't give a rat's ass, is drunk, and muttering "u ppl r stipud?"

A couple more comments:
1. The word "zillion" should never be used in any scientific treatise written in English nor, quite likely, any of the other modern languages.
2. A black hole, by it's very nature, cannot be photographed, felt, sniffed, nor made into "a stack of printouts," unless you were well within the event horizon (and probably not even then), in which case you would be, as Einstein might have put it, "geschkrued."

Pet peeve of mine: people confusing it's and its. Oops.

Yeah, you fools keep laughing. Im stocking up on the bottled water and duct tape.
You know if you dont seal out the oxygen from your house the black hole wins.

its a movie.. get over it and get a life.. stop arguing over the net because something in a f'n movie doesnt make sense.. or is impossible.. movies like that "scifi" movies are there to entertain us.. not to follow the rules of the real world.. if you want realism go watch some dramas

goto the arnold forum and talk about how impossible it is for him to be a machine from the future.. or how he can take on 300 guys with 1 pistol and 1 clip

its a movie.. get the F over it you little kid

if the war on X-Men 3 wouldv'e been started because professor X ate bad guacamole the movie would've so ruled!!!!!!!!!!!!!!!!. BRING THE BAD GUACAMOLE ANGLE IN X-MEN !!!!!!!!!!!!!!!!!!!!!!!!!!!!!1

all i know it's that they will try to make a blackhole next year

I do believe that at I am correct in saying that EVERY galaxy has a black hole within it.Therefore I would say that they are indeed extremely important in the development of galaxies.Does this level out the string theory idea somewhat?

reply

about that earlier "a black hole sun would suck in the earth" thing

no haiku this time...

the gravitational force is:

-G[(M1*M2)/(|r|^2)]rhat.

G is a constant.
M1 is the mass of the Earth.
M2 is the mass of the sun.
|r| is the magnitude of the distance between the Earth and the Sun.
rhat is just directional.

therefore, if the sun suddenly turns into a black hole for no reason (and we assume its mass stays the same, because otherwise there's some crazy *beep* going on) then M1, M2, r (and thusly rhat) stay the same and the gravitational force remains constant.

if you're stupid, american-dreamer, don't post, ok?

Hi everybody, My name is Steven Hawking, I was doing a little in depth advanced research on my latest theory when I ran across your data. The proofs rendered on this thread have actually rendered me speechless(no laughing, please)and I have decided to retire and leave it all up to you guys. Time for me to roll off into the sunset(or perhaps a black hole). See you on the other side.....

Umm....why did the black hole in this movie act like a tornado? I'm not entirely intelligent on the subject of black holes but wouldnt everything be drawn into it?
including the atmosphere and light from the sun thats near earth?

reply

didn't even account for time dilation!!

What i have to say about this... The light in theory would be sucked into the black hole but could be limited AROUND the black hole since it would not get light not in the no return zone or what ever it was called. The atmosphere would only be sucked in if it was big enough besides by then I'm sure it would have sucked all of earth. The tornado thing I think was an effect for people to understand the destruction of this "Hole".

I thought this movie overall was a cool movie sure it may be unpauseable but was cool.

I think the film was presenting the idea that the black hole was growing- gettig bigger the more matter and energy fell or was sucked into it.

reply

The black hole was supposedly getting bigger as it absorbed more matter and energy, so eventually it would comsume the entire planet and beyond.
