Black hole swallow the earth?

Question

what if the hydron collider creates a black hole ...will the earth dissapear?

Answer 1

Everyone goes on about countries fighting wars that will cause the end of the world - be it due to politcal or relgious grounds.

Personally, I think these scientists are more likely to cause the end of our planet - they are s******g with things without knowing the full extent of their actions - maybe not this time but one day they will succeed where the US and Russia have failed and blow the c**p out of us all

Answer 2

It's 'hadron collider' you freaking moron!  

Answer 3

NO no no no no NO NO NO NO no no no no NO NO NO NO no no no no NO NO NO NO no no no no NO NO NO NO no no no no NO NO NO NO no no no no NO NO NO NO no no no no NO NO NO NO no no no no NO NO NO NO no no no no NO NO NO NO no no no no NO NO NO NO no no no no NO NO NO NO no no no no NO NO NO NO no no no no NO NO NO

i dunno how many more times i need to say it.  

Answer 4

"The black holes the LHC is set to create will only have the mass of a couple hundred protons."

The radius of such a black hole would be

Rs = 2(200)(6.67428e-11 m^3/kgs)(1.67262e-27 kg)/(299,792,458 m/s)^2

Rs ≈ 4.96844279e-52 m

and its collision cross-section would be

A ≈ π(4.96844279e-52 m)^2

A ≈ 7.75515458e-103 m^2

Because of its +200 charge the black hole would very rapidly collect 200 electrons.  The minute collision cross-section makes it improbable that any of these electrons would be absorbed; instead they fall into orbits  Now you have an atom of atomic number 200 which just possibly would have a collision cross section too large to penetrate the walls of the chamber.

If by remote chance all 200 electrons get absorbed by the black hole you now have a neutral black hole which could possibly orbit inside the Earth for eons before it collided with a nucleus.

Answer 5

No prob.

The worry by many is that there could be a production of anti-matter which could cause a shift in reality as we know it.

One particle of anti-matter shifting to another particle of matter.

Should be interesting if suddenly they turn it on and we are in the year 2397 and living on an Earth like moon with a moon like earth, and we are derived from fleas.

If it happens, can I have a larger bank account (in credit), and mines the flea with the sultry brown eyes.

Answer 6

No. It would only create very tiny black holes, which would explode in a tiny fraction of a second due to quantum effects. The energy levels achieved by the Large Hadron Collider will be no higher than the energy levels achieved by cosmic ray bombardment, so if the LHC does successfully create black holes, it will mean that black holes are coming into existence and exploding more or less constantly in the air over our heads, and have been for billions of years. Scientists would actually be very excited to see black holes being created, because in laboratory conditions they would be able to measure the energy given off by the black holes as they explode and determine whether or not any of the energy is being lost into other universes.

Answer 7

If during the first milliseconds of construction it can begin 'feeding' on matter around it, it could keep growing. The odds aren't good though as you would have to have billions of particules ALL colliding at the same time to create inertia energy for initial construction. Odds are amazingly against.

And 'if' it did happen you would'nt know anything about it anyway as the initial growth would take in this planet and the surrounding solar system in fractions of a second. Cool Q.

Answer 8

unlikely but possible. don't think that anyone knows what will happen

Answer 9

The LHC poses no danger WHATSOEVER. The worst POSSIBLE outcome is that it doesn't work, and we wasted millions of dollars. And that would suck. But black holes swallowing the world? No.

Lets start with a very basic astrophysics lesson. Black holes don't always have an infinite amount of gravitational force. There are tons of "roaming" black holes which range in size from a tennis ball to a planet. Fortunately, no planet-sized black holes are near us. The gravitational pull of black holes if calculated by its mass. For ever kilogram of mass, there is a force of .000000000066726 N. This means for every kilogram of mass that I have, I have .000000000066726 N of gravitational force. The black holes the LHC is set to create will only have the mass of a couple hundred protons. But for calculation's sake, lets pretend the LHC exceeds all wildest expectations, and creates a black hole of 1 kilogram. This black hole would have .000000000066726 N of gravitational force. My dog weighs 10 kg. His gravitational force is .00000000066726 N. So my dog has a better chance of sucking up the world than this black hole that exceeds all expectations of the LHC creating.

And these black holes won't exist for more than a thousandth of a second. There is something called "Hawking radiation". It is the principal that black holes emit radiation... highly charged particles of matter is has consumed that has been compressed to the point where we have these highly charged particles. These particles come out of the black hole, and thus the black hole looses its mass. Because of this, these black holes won't live for more than a second.

To put it in prospective, if the sun were to suddenly disappear, and a black hole of the same mass would replace it, the planets wouldn't be sucked in, they would just continue the normal orbit. The mass is exactly the same. Now the lack of light would present a few problems, but we wouldn't be sucked in.

And when we say that "it is going to recreate the initial conditions of the big bang" it simply means that we are going to create temperatures and densities of roughly the same value as those which appeared at the beginning of the big bang... we aren't making another big bang. People seem to think that they know more about this than the thousands of astrophysicists and particle physicists that are running the LHC.

And we have already performed some of these experiments. In 2003 we ran a couple experiments almost the same to the runs we are going to run in a couple months, and the world didn't end then, so why would it end now?

Answer 10

no. The black hole will be unstable and will last only microseconds. It will not be able to accumulate mass due to its size.

Answer 11

No.

How many of you "end of the world" muppets actually know about the science behind particle accelerators? Very, very few, I suspect. So what grounds do you have for being scared about the LHC, when you don't even have the most basic grasp of what it is actually designed to do?

Answer 12

They only leaked out that it will cause miniblackholes and spacetime rips so they can use it to explain the sudden appearance of Type III 'aliens' and fake 'messiahs'. Many will be fooled...

Google/youtube: "Project Bluebeam"

Later, ask yourself how we knew in advance.

Answer 13

To say it without a formula: even if you compress the whole earth into a ball the size of your fist (which is impossible, really, no energy on earth could do this), it wouldn't be enough to create an event horizon, the point in spacetime where light cannot escape. So there is no possibility that something created by humans can suck in the earth, because its mass is not enough, and there are no small black holes, just black holes with several times the mass of our sun. Yes, not even our sun can become a black hole by itself, it needs that much mass and gravity.
