Are you scared of black holes on Earth?

 


Neilos
Now that we have the LHC built by CERN. Are you concerned about the fact that they can potentially create black holes here on the surface of the Earth?

No, I'm not. A black hole requires a lot more mass than those scientists have to work with.

As for a 'tear in the fabric of the universe', I doubt the fabric of the universe is so fragile.

I'm actually hoping they DO produce some micro-black holes. It would provide confirmation for the 'Hawking Radiation' hypothesis and would also provide strong circumstantial evidence for string theory (since according to 'classical' physics there is no possibility of a BH if the inverse square law of gravity does indeed hold in the sub-atomic realm).

Let's take all our enemies down with BH, shiiuuuuu don't tell anyone or they will notice...

Sound like a new Dan Brown novel Smile

I agree with ocalhoun, but I'm more worried that the thing will malfunction again and be postponed again. Stupid 10-ton magnets...

But doesn't this mean also that if proved wrong it'll never get smaller? Potentially only getting bigger! It'll surely just start to gobble things up? lol.

Only if you think that a Planck-scale black hole can 'gobble-up' atoms. I suggest that a brief overview of scales might re-assure you. Pay particular attention to the potential event horizon (ie the 'gobble radius').

Yeah, don't worry about the LHC creating black holes. Anything that can happen there is already happening in the Earth's atmosphere on a daily basis. Cosmic rays with much more energy than the LHC could ever achieve are constantly bombarding the Earth. Whatever happens at CERN will have already happened countless times in Earth's atmosphere. Last time I checked, we have not yet been swallowed up.

The big result I'm waiting for is data regarding the Higgs particle. If they can actually detect it and measure it's mass, that will go a long way towards resolving many questions currently plagueing the standard model of physics. Actually, it will probably create more problems than it solves, but it will still be very, very interesting.
