Forget recession! It might not even matter anymore!

i assume they have done similar tests reaching say 50.000 times hotter than the heart of the Sun. A step by step approach is more reasonable i want to believe.

i trust those scientists but i am worried because this is extreme science and humans arent perfect. I take their words for granted because science job is not to tell lies , thats religions job

The temperature doesn't really matter, it's the particles created that could in some theories become a problem due to further reactions that might happen with the normal matter making up the Earth etc.

There are quite a few particle accelerators up and running already so we have quite a bit of experience operating at lower energies then LHC will be capable of + I think it'll take quite a while for the LHC to reach peak operating power since it'll take a lot of calibrating etc.

So under what conditions can these strangelets cause non-strange matter to become strange?

I never said it could. I believe the main reason we haven't had a problem so far is because the particles created decay quickly + their charge means they're repelled from regular matter. There are loads of theories regards this stuff so if you want to learn more about it I'd read up on the experiments described on the
Brookhaven Lab website I linked earlier.

conditions like those recreated in CERN can be found in space? or is it the first time since the bang?

They happen in lots of places, the usual one that the accelerators are compared to being the collisions that occur when cosmic rays smash into our atmosphere. These are extremely high energy and countless billions of collisions are occurring every second.

Well I just ask because one of my professors is working on the LHC and was telling me how the strange matter 'problem' is the only one he can't completely rule out. He said that the whole issue stems from the possibility of 'normal' matter being only a metastable state of matter and strange matter being at base stability.
 
The Interplanetary Medium is local, to a solar system (any solar system.) The Sun radiates charged particles (the solar wind.) This permeates throughout the solar system, to the heliopause.

CMB is the residual echo of the big-bang, i.e. approx. 2.7 degrees above Absolute Zero - actually the first light exuded by the creation of the Universe at circa 400,000 years or so.

Well I guess if he is still teaching he's not too heavily involved in the LHC.

Generally speaking though scientists don't like to rule anything completely out, especially when it comes to exploring high energy physics!

:) I misread that last bit then and thought you were saying the Universe came to be 400 000 years ago :eek::eek: Then I read more carefully.

That's why I also cited the interstellar and intergalactic media ;)

Also, 'Solar System' refers specifically to the planetary system around our star, Sol, not to any old planetary system. One of my bugbears, that, sorry :p

I know; he was probably just being flippant, he likes to do that :p

Apologies, I didn't bother with your links - just wanted to post a quick definition. Also for the 'Solar System' correction - I hate that one myself, serves me right!!

That's not quite true. The possibility is real, if minuscule. We just don't know enough about high energy physics to be totally sure, hence why we're doing the experiment.

That's quite funny.

There's not enough energy, we failed ! :(

There are LOADS of engergy........oh crap.....................:eek:
 
ahh the hadron colider been reading about this for about a year. cant wait to see the outcome. some of the scientists ideas sarrounding it are so funny tho but then again im not albert einstein, a few are saying that if things go to plan we may go back in time okay then.

also a few have advised that world could end because they have never tested anything with such a high power of energy. :P

will be intresting tho imo
 
Round and around she goes. Where she stops, nobody knows.

Substantial funds now come from charitable organisations as well as private backing. Of course you also have massive research councils giving out grants. The HEFCE alone gave out £7 billion last year in research funding - and you know most of that was for part privately funded work.

That's probably true, but with the STFC incessantly bleating about cutbacks it really doesn't give out a good image, does it? :(

Inquisitor said:
Yes, you're right. All of the academics and PhD physicists working on this from hundreds of countries around the world are, in fact, secretly trying to design a weapon system for the military.

Not to mention all those thousands of volunteers helping out via LHC@home. Maybe Bush was right - Iraq's WMDs were on their computer screens.

Moo

It's quite pathetic really, we claim to be an enlightened people, but you still get large numbers of morons who's first reaction is "this is big and confusing, it must be dangerous"

How caveman is that?
