CERN physicists create record-breaking subatomic soup

Physicists at CERN’s Large Hadron Collider have achieved the hottest manmade temperatures ever, by colliding lead ions to momentarily create a quark-gluon plasma, a subatomic soup and unique state of matter that is thought to have existed just moments after the Big Bang, Nature News reports.
ALICE physicists, presenting on Monday at Quark Matter 2012 in Washington DC, said they have achieved a quark–gluon plasma 38% hotter than a record 4-trillion-degree plasma achieved in 2010 by a similar experiment at Brookhaven National Laboratory.

A miniature black hole created in this manner would evaporate via Hawking radiation long before it got close enough to any matter to start feeding; Hawking evaporation speeds up as the size of a black hole decreases.

To kill us, all a Black hole has to do is gobble up all the material of earth, regardless how big it is.

time & space………… r 2 different things folks.. space was created through time..i know a secret———— ask yourself- what was there before time ?.. A VOID.. nothing, the reason ———–light travels at the speed of light is elementry. before light, time did NOT exhist, got it ? another 1 “why is every planet round”.. ….?… simple.. because it is the most energy efficient shape

it’s called———– the time space continuam, where time & space tear the fabric henceforth creates a dimention we are not awear of in this time.. weird..

Is there a minimal mass to a black hole? My assumption is that density is the key factor. And wouldn’t a small one start pulling in matter from it’s surroundings? Would it stop absorbing matter or accelerate as it dropped to the center of the earth and started absorbing liquid lava.
From Wikipedia:
A black hole is a region of spacetime where gravity prevents anything, including light, from escaping.[1] The theory of general relativity predicts that a sufficiently compact mass will deform spacetime to form a black hole.
compact mass=density

If they can create two collisions of this magnitude, almost simultaneously, they should be able to create something as subtle as a rift in space. How exciting! These collisions should start a wave of considerable magnitude.

If they can produce two almost simultaneous collisions, perhaps they will be able to create a rift in space. Won!t this be exciting!!

Obviously you don’t have any idea what a Black Hole is. Earth does not have enough matter to create a Black Hole large enough to kill us.

mhmm. Just a little more juice and you’ll create a miniature black hole and kill us all. Perhaps some Einsteinian thought experiments for you boys instead. Sounds safer and it will save everyone a fortune. Ever increasingly powerful supercolliders that eventually create a black hole, genetic programming that evolves to survive the selection criteria defined by the programmer, and SETI finding alien moral intelligent life that allies with our cows top my list of suicidal technologies. And I’m pro-tech, anti-luddite. I’ve quit burgers myself.
