Will Large Hadron Collider (LHC) kill us all? ?

Question

Maybe that is being too alarmist. However I think we should be concerned. I really do not put much faith in the idea of top quarks or the totally ridiculous "strangelet"

Any black holes created will supposidly decay into Hawking radiation in a short time, however this is somewhat less that an educated guess (uneducated guess ?) I say this because there is no information beyond speculation on this.

So, anybody have something highly intelligent to contribute?

Answer 1

Highly intelligent to contribute???

You mean something like 'Will LHC kill us all?'

I recommend putting it on a sign and go out and stand on your local streetcorner with it.

People will admire your intellect.

Answer 2

For the umpteenth time, no it won't. The world is not going to end in 2012 and yes, we did really go to the moon.

So you think you know better than Stephen Hawking, then? The only uneducated guessing that I've seen is this ludicrous, alarmist doomsday talk. It's a complete storm in a teacup. Physicists probably laugh at people like you.

Answer 3

No no not at all. Some uneducated media people have released this. If it could kill us than no country would have allowed this and there would be wars before LHC is activated. LHC would be used to find out about the origin of the earth.

Answer 4

concerned about what, exactly? why should we be concerned?

think it through (i know, not a strong point around here): the scintists in question are not suicidal, nor are the ppl who put up the money to build lhc. they want to learn new things about the universe, and have a wonderful new instrument to do it with. i wish them well, and i envy them.

do you actually know anything about particle physics? or are you just repeating nonsense you read elsewhere? if you want intelligent answers, please ask an intelligent question.

Answer 5

Physicists Steven Giddings and Michelangelo Mangano have ruled out the potential for dangerous, stable black holes to be created in a paper entitled Astrophysical implications of hypothetical stable TeV-scale black holes published in the journal Physical Review D on August 15, 2008.  

Answer 6

Three weeks ago I suffered a heart attack followed by a cardiac arrest of five minute. I am one of the five percent survivor of such an accident.

My friend, stop smoking, exercise and eat healthy. You have much more chances to die from a heart disease than any experiment that will happen under the ground between the Swiss and the French border. Live happy and forget the doomsday prophets.

I was 12 years old during the Cuban crises and was so scared of a nuclear war. It never happened. But it was much more real than all of the apocalypses you can find here:

Answer 7

No, but in 2012, aliens that come out of our toilets will kill us all.

Answer 8

the LHC is capable of killing every man, woman and pet on Earth, assuming you can find a way to drop it on all their heads.  Its pretty heavy.  Sorta like an ACME anvil.  Now, that's a weapon.  I hear the US Army is trying to figure out a way to drop anvils on the Iraqis.  I think it involves portable holes, but I might be wrong about that.

Answer 9

Too alarmist: No. Alarmists react strong on real dangers. You react on not existing dangers. That is no sane reaction. (And that was the most intelligent contribution of me to the question.)

We should be concerned: Yes, but not because it will destroy the world. It won't.

Strangelets are theoretical possible particles, which have not been observed in nature and nobody can even explain yet, how they should be created. All theory about strangelets is based on playing LEGO with quarks.

If Black holes are created inside the LHC, the theory which predicts Hawking radiation to exist must also be true - both are based on the same physical model. Without hawking radiation, but with the lower energy requirements, the universe would be full of small black holes - which is not the case. Anything below stellar size was not observed yet. So either the energy required for creating the black holes is much higher as the energy possible with the LHC and the black holes are stable - or black holes can be created from relatively little energy, but are not stable.

This is no educated guess - it is a theory derived from a possible explanation how the matter interacts. A guess gets created out of nothing, a theory is created from observations to explain these. A theory is correct only as long new observations also fit to the predictions of the theory. Many aspects of this theory are already validated by accelerator experiments, but some predictions require the higher power of the LHC to become tested.  

Answer 10

Short answer and a direct one........No.  I query your lack of faith in top quarks or strangelets.  I have a doctorate in physics and work as an astronomer and cosmologist, and accept them both.  What are your qualifications that give you such an insight?  On another level,  I hope in the next couple of years, to get some time on the LHC as part of the American team, and I can assure you, if I thought it was dangerous, I would avoid like a rabid skunk!

Answer 11

Not really.

Potato.

Answer 12

Its just going to be used to trick the ignorant that it opned up a "doorway" or "stargate" for fake Type III 'aliens' to come through:
