"1 cubic centimeter would weigh 40billion tons"

A superhot substance recently made in the Large Hadron Collider (pictures) is the densest form of matter ever observed, scientists announced this week.

Known as a quark-gluon plasma, the primordial state of matter may be what the entire universe was like in the immediate aftermath of the big bang.

The exotic material is more than a hundred thousand times hotter than the inside of the sun and is denser than a neutron star, one of the densest known objects in the universe.

"Besides black holes, there's nothing denser than what we're creating," said David Evans, a physicist at the University of Birmingham in the U.K. and a team leader for the LHC's ALICE detector, which helped observe the quark-gluon plasma.

"If you had a cubic centimeter of this stuff, it would weigh 40 billion tons."

Densest Matter Acts Like Perfect Liquid

By triggering hundreds of thousands of high-speed collisions each second, physicists using the LHC hope to break subatomic particles into even more basic forms of matter, which can be used to study what the universe was like a trillionth of a second after the big bang.

LHC scientists made the quark-gluon plasma last year by smashing together lead ionsólead atoms that have been stripped of their electronsóat nearly the speed of light.

As the name suggests, quark-gluon plasma is made up of quarks and gluons. Quarks are the elementary building blocks of positively charged protons and neutral neutrons, which make up atomic cores. Gluons are particles that "glue" quarks together using the so-called strong force.

It's thought that, as the universe cooled, the quark-gluon plasma that existed after the big bang coalesced to form matter as we know it today. (Related: "Strange Particle Created; May Rewrite How Matter's Made.")

The quark-gluon plasma created at the LHC is about twice the amount and about twice as hot as quark-gluon plasma previously made using the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory in Upton, New York.

Still, the plasmas created by the two machines are very similar, scientists said this week during the Quark Matter 2011 Conference in Annecy, France. For example, scientists have now confirmed that both versions behaved like so-called perfect liquids, with nearly zero friction.

I'd been wondering about this very thing.

These scientists obviously haven't discovered the orangemane.


Can a knowledgeable person tell me the value of understanding what the universe was like a trillionth of a second after the Big Bang? I'm pro-science and pro-learning, but I'm just wondering what the path is from this research to something that helps humanity. Will it help us achieve faster than light travel? Teleportation? Anti-gravity?

No, but it will help HCF explain away that extra twenty pounds he was wondering about.

That'd be a great practical joke. Slip a few atoms of this stuff into someone's cereal, and suddenly they're 4,000 pounds overweight.

They're working on a waffle that won't get chewy in the microwave.

Why explain it away?

I love waffles. How do you prepare the leftovers? MW sucks, makes em soggy. Toaster makes the outside too crisp. Broiler? No.

I make great sourdough waffles. Yum. With real Maple Syrup only.

Lets get this figured out.

For a brief moment I thought the thread title was an attempted run at Ugly Duck

I dated a girl that had the densest matter possible between her ears. VERY easy on the eyes, but just like a black hole, she sucked the energy right out of you. Your IQ started free falling within minutes of starting any kind of discussion with her. Now that I think of it, I am sure she was a Bronco fan!! :p

Too bad those pyramids werent made of this stuff. then we'd really be scratching our heads.
