About CERN's September 10th Experiment?

Question

What's the likelyhood that something will go wrong where a black hole will be created and engulf everything?

Answer 1

Even if they were doing collisions on the 10th, the chances of some sort of disaster is zero.

The LHC gets a particle moving at high energy and smashes it into another. That's all it does.

But this experiment has been going on here on Earth since the Earth formed. High energy cosmic rays, which are typically atoms stripped of their electrons, have energies much, much higher than the LHC can produce. While you've been reading this, several have passed through your body. And sometimes these things do a head on collision with the stuff of the Earth. If the LHC can create a small black hole, then so can cosmic rays. The Earth is still here, so it's safe.

Answer 2

0%

They are not doing any collisions on September 10th, they are just sending the first beams through the accelerator for calibration. This will take one month, before the first test collisions happen  in October.

Even then, you still have not enough energy for creating a Black hole, as they operate on low test power this year.

Next year, you still have 0%. If the LHC could be able to create hadron-sized black holes (and that is really small, even smaller as the size of a atom) at full power, these black holes would have some special properties: They will decay very fast (not even a nanosecond) and they will continue to carry the charge of the particles which collided to create it. Even if it would leave the vacuum tubes of the LHC, which it couldn't because of the charge, it can't collide with enough matter to become stable.

You always have to remember: If the "LHC will create a Black hole" chicken littles would be right and scientists, the universe would be full of small black holes. But as far as scientists can tell now, there is a very high minimum mass for a black hole in nature. The conditions inside the LHC also exist in the upper atmosphere of Earth, when cosmic radiation collides with the atoms of the air. But no satellite ever got absorbed by a small black hole.

When the LHC would be able to really produce black holes, it would help explaining why there are so few black holes. But only few scientists really expect that the LHC can even create black holes, as it requires many complicated other conditions to be fulfilled, for example other dimensions to exist, which are also rolled up into strings.  

Answer 3

Lord, whats wrong with you!

Don't you know that everybody on here knows that the people at CERN are perfect and never make mistakes! You must be the dumbest human alive!

I don't think there is much to worry about, but I'm really not qualified to answer that. If they like it or not, neither are most people on here.

It seems to be a heated issue and if you say anything about a possibility of danger people are all to quick to tell you how ignorant you are. Seriously everybody needs to chill out about this.

Answer 4

IT'S A BIG RISK!  

Answer 5

0%

people don't seem to get that the blackholes created will be so small that they will simply vaporize

Answer 6

Zero.  The 10 September event is sending a low-energy proton beam in one direction around the LHC as a proof of concept.  No collisions, no chances of anything interesting happening.  It's probably not going to be until sometime next year that they'll have the two proton beams active and the power levels anywhere near the interesting level.

Answer 7

0%. People don't seem to realize that cosmic rays constantly strike the Earth's atmosphere with energies orders of magnitude beyond that which will be generated at CERN and don't produce Earth-eating black holes.

Answer 8

none whatsoever.

where did you get the idea that something else might be the case?

this has been asked at least 10 times today. where is this garbage coming from?
