Large Hadron Collider (LHC) Generates a 'Mini-Big Bang'
buildslave writes "The Large Hadron Collider has successfully created a 'mini-Big Bang' by smashing together lead ions instead of protons. The scientists working at the enormous machine on the Franco-Swiss border achieved the unique conditions on 7 November. The experiment created temperatures a million times hotter than the center of the Sun."
So, is a mini-big bang just a bang, then?
I hate this constant need for science journalists to oversell and over-hype an outstanding achievement with misleading hyperbole. They didn't create mini big bangs. They smashed lead ions to try to recreate the conditions that existed shortly after the big bang. It's already an impressive enough achievement without cheapening it with sensationalist BS.

Wouldn't a mini big bang just be a moderate bang?
Evil people are out to get you.
Now, if we can just wait a few billion years, a suitably intelligent species should evolve inside the newly created universe and build a Very Very Very Small Hadron Collider(VVVSHC) in order to investigate the conditions of their early universe....
Last I checked they weren't mutually exclusive.
The window in which you can make stupid comments about playing god and recursing (no tired xkcd links allowed, about either pebbles or carving dice) is now closing. Please get in your cheesy gloom-and-doom scenarios ASAP, and make wild, uneducated suppositions about micro black holes while you're at it.
Bio questions? Ask me to start a Q&A journal. Computer analogies available for most topics!
The output energy probably wouldn't have exceeded the input energy. No chain reaction or anything.
I'd imagine a mass the size of two lead ions at a trillion degrees could only maybe bring a gallon of room temperature water up a degree or two. They are quite small.
Is that what they call "sexing-up" the story?
General Relativity: Space-time tells matter where to go; Matter tells space-time what shape to be.
I think if they created a real big bang we may all be silenced.

If we are gods, we can only hope our creations are morally superior to us.
Hey, suddenly Jehovah the blood thirsty desert god makes a lot more sense.

The title is misleading. The LHC did not create a mini 'big bang' but created a miniature of the conditions that might have existed shortly AFTER the big bang. The 'big bang' was the event that created all mass, space, and time in the entire universe in a single instant approximately 13.7 billion years ago. The LHC collision of lead ions did not create any mass, space, or time but did create a "hot dense soup of quarks and gluons known as a quark-gluon plasma" that might have existed after the 'big bang' event.
Indeed. A roommate of mine, who was a religious micro-biologist, insisted that evolution, more-so than anything, is indicative of Intelligent Design/Creationism. In his own words, "What's smarter than designing something that can adapt to its environment entirely on its own?"

Nah, it's just monday...
Men rarely (if ever) manage to dream up a god superior to themselves. Most gods have the manners and morals of a spoiled child.

NVidia achieved that years ago.
Oh, that is FAR above the temperatures needed for controlled fusion.
We don't have any trouble creating the necessary temperature for controlled fusion. The part we aren't able to do is the "controlled" bit - in a way that allows a net positive energy return.
I'm guessing this collision released maybe a few kcal of energy (which is HUGE for two atom-sized masses, but otherwise on-par with a candle), but it probably consumed the resources from half of a power plant in the process.
The LHC isn't about energy generation - it is about generating huge concentrations of energy in an extremely small volume of space.
And if we do it all together, is it a gang bang?
Enjoy life! This is not a dress rehearsal.
Uh, that's what "mini big bang" means. OK, so you don't like it, but who cares.
It isn't cheap sensational BS, it's expensive evocative BS at worst.
100% agreement. Its ridiculous for the OP to get a bug up his ass over that headline. Headlines need to be short and sweet (aka maximally informative to the intended audience) - the BBC's headline is both, the OP's version is far too long to use as a headline. Might fine for the title of a scientific paper, but not a general news website.

Freeon is the open source version of Freon, and is more properly called GNU/Freeon.
I prefer rogues to imbeciles because they sometimes take a rest.
I'd imagine a mass the size of two lead ions at a trillion degrees could only maybe bring a gallon of room temperature water up a degree or two. They are quite small.
Just to keep things in context, they actually shot a rather large number of lead ions at each other in the hopes of getting two to collide.
There's a huge amount of energy zipping around, it's just that the odds of it all releasing at once approaches zero.

o0t!
Then He/She/It/They shouldn't have created us with a brain that was capable of designing and a body capable of executing those experiments, or He/She/It/They should have kept an eye on us and smacked our hand if we tried. IMO deadbeat deities shouldn't get to wander back into our lives after a long absence without any clear communication with us and immediately get to dictate what we can and cannot do.
You are quite a long way off with your estimate, though you're right that the effect would be small.
One mole of lead is 207 grams so the energy you are talking about would cause a 1 K rise in only (207 * 2 * 10^12) / (6.02 * 10^23) or 6.9 * 10^-10 grams of lead.
That's less than the mass of a human ovum. Orders of magnitude (mass)
And the heat capacity (by mass) of water is about 32 times that of lead so you could heat up even less than that - just over 2 * 10^-11 grams of water.
That's what the Free Mesons want you to believe.
we've been unable to prove anything so far, but here's a story pulled out of the collective asses of village elders 3000 years ago...
Actually, if you replace "village elders" with "theorists" and 3,000 years with "several" this is almost exactly like science: we come up with a theory which we have not yet proved and then act on it as if it were true to see what the implications are and then test those implications. The slight, but very important, difference being that if someone manages to prove the "story" wrong we'll listen to them, give them a nobel prize and rewrite the story whereas religion has a bad track record of burning them at the stake (although even science's record is not blemish free).
