False Vacuum
Re: False Vacuum
The quark gluon plasma has been created and studied at RHIC.

Re: False Vacuum
But according to Wiki it's still theoretical and is different than the fireballs which were created at RHIC. Maybe I'm paranoid but have they considered my questions?

Re: False Vacuum
I don't follow your reasoning. What I read seems to say at least to me that a QGP has been created. I don't understand your suggestion that there are different forms QGP. I seems to see the QGP as the same no matter where it is created.

Re: False Vacuum
In the "how it is created in the lab" section the following sentence is written -
So it means this particular kind of fireball hasn't been created yet. But is it possible, in any way, that this plasma was what caused a phase change of the universe in the past? Is it completely ruled out that high temperatures and high densities don't cause vacuum bubbles to form?They largely pass through each other, but a resulting hot volume called a fireball is created after the collision. Once created, this fireball is expected to expand under its own pressure, and cool while expanding. By carefully studying this flow, experimentalists hope to put the theory to test.
Re: False Vacuum
I disagree. I read "fireball is created after the collision" as saying that a QGP is create since that is what the fireball is.

Re: False Vacuum
Okay, so basically the LHC will create the exact same fireballs created by RHIC? Are those fireballs also created by cosmic rays?
Since they are going to do 3.5 TeV energies soon, I hope to be completely calm by that time.

Re: False Vacuum
I think on a very fast read that this document says that QGPs are the best explanation for the results from some of the most energetic cosmic rays.

Re: False Vacuum
Well I don't understand a lot of what's written there, but I got a reassuring feeling that the LHC will explore things already present in the universe, and won't create vacuum bubbles (it remains the scariest doomsday theory I've ever heard).
One more thing - it says that 1-14 TeV corresponds to an energy of 10^17 in cosmic rays. Since The highest cosmic rays observed were at 10^20, what amount of TeV energy will a collider need to exceed this energy?

Re: False Vacuum
I've heard its around 100 TeV + tho I've also noted in some papers stuff upto 1 million TeV
EDIT that "OH MY GOD" cosmic ray that hit us in 1991 was ten millions times higher in energy than the SSC that would have had an energy of 20TeV.
So pretty nuts some of the natural stuff.

Life was so much better before I knew about this theory.

Anyone who doesn't take truth seriously in small matters cannot be trusted with large ones either by Albert Einstein.

Hi Stephen
Exactly what in that video do you find be so worrisome?

Re: False Vacuum
Just the reinforcement of the idea that theoretically a quantum tunneling event could happen at any second and everything would just disappear. I know the chances are astronomically low and all, but just the thought that a vacuum bubble could appear right now and kill me is terrifying.Allan wrote:Hi Stephen

True, but sometimes you can't control it (or the world).emmylou wrote:Stephen life would be so much better if we stopped thinking about everything
