Large Hadron Collider Proves The Universe Was Once A Liquid

The world's most powerful particle accelerator smashed together lead nuclei at the highest energies possible, creating dense sub-atomic particles that reach temperatures of over ten trillion degrees. Beyond being awesome, this achievement shows the early universe was actually a liquid.

Normal matter can't exist in any form at these sort of absurdly hot temperatures. Instead, matter is thought to melt into a strange, soup-like substance known as quark-gluon plasma. Researchers are still investigating exactly what happens when this quark-gluon plasma emerges, but the early results seem to confirm the theory that the plasma acts like a liquid, not a gas.

Earlier research had shown that the sub-atomic fireballs acted like liquids at lower temperatures, but there was still some expectation that they would move into more gaseous behaviour when temperatures got hot enough for the plasma to emerge. University of Birmingham astrophysicist Dr David Evans says these findings should also reflect what the universe looked like in its first microseconds of existence:

"Although it is very early days we are already learning more about the early Universe. These first results would seem to suggest that the Universe would have behaved like a super-hot liquid immediately after the Big Bang."

Further study will be needed to better understand just how the quark-gluon plasma acts at these trillion-degree temperatures. Researchers have already made one unexpected discovery. It turns out the fireballs caused by the collision create way more subatomic particles than most models would expect, as researchers were able to observe thousands of particles radiating out from each fireball.

    It's SCIENCE!!

    The quote reads "seems to suggest". The headline reads "prove". Hmm.

    Not that i intend to turn nerdy nerd over here, but the correct headline should be:

    "Large Hadron Collider Proves The Universe Once ACTED LIKE a Liquid"

    Remember that liquid and plasma are two distinctly different states of matter!

    does this mean we're all part of a small rain drop in another universe that's having a rainy day and when we hit the ground our universe will be destroyed?

    How come it's a given that the 'universe' was created with a 'big bang', and now scientists are trying to prove it. Why would you try to prove something happened if it 'happened'.

    It would be interesting to hear their explanation as to how less information creates more information. For example, there's a lot more information in a strand of human DNA than a lead nuclei. Duh.

    Science isn't subject to science anymore, just non-realities.

    Is it just me, or did anyone else think of LCL from Neon Genesis Evangelion?

    This creeps me out.
