I can't wait to get home and see this video! Is this really possible? Big bang and mini black holes? Have I turned a blind eye for that long? Damn!! That is so cool! But of course I need to see the video first.

Well apparently what they're doing will being able to test the big bang theory and black hole theory on a small scale because of the intense energies it'll produce.
Really intriguing stuff!

Anyone know where i can keep up to date with what's going on over there? ;)

Screw the atomic bomb.  Imagine if we dropped a black hole on Japan.  Or sucked them up in a mini version of the sun.

  In 2006, Brian Cox came out here for Australia's National Science Week and I went to see him talk about it.  That's when I first properly heard about CERN's LHC project.   It was really mind-boggling to consider exactly what they were hoping to uncover.  He managed to explain it fairly well to us n00bs.   I think just getting to this point in human knowledge is amazing.  I'm truly impressed by modern particle physics, even if this project ends up being a bit of an anti-climax.

Haha, that's about the whole of it ;)

They've got two seperate rings around the 26km accelerator, and each one will have protons going around at almost the speed of light.
One ring goes one way, one goes the other ...
And there's 4 'colliding chambers' around the LHC, such as ATLAS, and in those chambers, the two rings cross eachother, and well ... that's where the action happens :D
There's incredible cameras in each chamber, and basically they're just going to look at what comes out of the collisions, and hope to find the Higgs Boson, and maybe evidence for higher dimensions and whatever else they're looking for :)

Hope i've helped :)

You're welcome :)

I'm not too sure on the whole Physics of it really, complex stuff haha
All i know is that they need to cool the system to almost absolute zero (-273oc) by using liquid Helium or something for it to work, and that a lot of magnets are used to accelerate and guide the protons around the ring.
So i'm guessing they have pretty powerful magnets ::)

That's really all i know, i'll look into it a bit more :)

Heat and pressure speed up the particals, takes days to get it fast enough. Or something like that. :P


Oh And What If...
They create loads of little blackholes that join into one, and get like massive, so they cant control it, and it sucks in the earth?
Think that would ever happen?

It's not heat that does it, because the system is cooled down to almost -273oc before using it :D

And the possibility of creating black holes is minute, but if they do, it's predicted that they wont even last 1 second because they'd be so unstable :)
If what you said could happen though, it'd be a good way to go wouldn't it ::)

I'm 24 and I still need instruction.

It is cooled down to -274K, but they then create an explosion of sorts, by colliding the particles.  Cooling it down is just to create the same sort of conditions that the Big Bang would've occurred in.  It doesn't stay that cold - energy will be released.

Collisions of the same kind happen out in space and to the earth all the time, and they don't eat the universe.

Well, they are accelerating mostly Lead ions.  Ions are charged atomic nuclei, charged because they have too few electrons, in this case, probably none at all.  Any charged particle will accelerate in the presence of a magnetic field.  The LHC has superconducting magnets along it's entire ring...

Figuring it out yet? :)

The magnets are cooled, not the collision chamber.  The cooling doesn't affect the collision/particle explosion.

Cooling the magnets is necessary because they are superconducting magnets, and superconductivity only occurs at very low temperature.  Although scientists are trying to achieve higher temperature superconductivity. (ie: room temperature)

And just FYI: The LHC's magnets are cooled to: 1.9 K (-271.25 °C).

Title: Re: Scientists attempt to recreate the Big Bang!!
Post by: bahramthered on September 08, 2008, 10:15:38 AM
Basically the idea is that each magnet pulls the electron towards it, and when it reaches it flips it's feild to push it away.

The magnets need to be cooled as this helps them acheive max effect.

On the whole notion on "mini black holes"

First, the size of a mini black hole as reported by many scientists working on the project would be on the subatomic size, think protons and neutrons.

Second, these mini black holes are unstable.  As proposed by Stephen Hawking, (a truly great man :)), these black holes would emit radiation rather that "gobble everything up."  Almost as soon as they were created these black holes would emit enough radiation that they destroy themselves.

Just imagine 2 guns pointed barrel-barrel.  When both are fired both bullets collide with each other and melt, bend, emit fragments etc.

Same principle here.  Particles colliding with each other and scientists are going study all the fragments of subatomic and subsubatomic particles to see what gets made, energies released, etc.

They're not trying to make black holes, the sole purpose of the experiment is to finally detect higgs-bosun particles, which are believed to be the particles which are responsible for giving the universe mass. This whole experiment may finally bring to light all the questions that science has regarding the big bang and it's inception. The amazing thing is that we can only actually detect 4% of the universe. That means 96% of the universe is comprised of black matter and black energy. I wonder what is in that 96%......

No actual "Big Bang" will occur.  The theoretical masses and energies needed for the original big bang were IMMENSE!!!  According to big bang theorists everything in the universe, everything that you can look at, touch, every atom, everything... was compacted in a single infinitesimally small speck.  Nothing the scientists are going to do tomorrow will even come close to this amount of mass and density.

Large Hadron Collider: Best- and Worst-Case Scenarios
http://blog.wired.com/wiredscience/2008/09/the-bosons-that.html (http://blog.wired.com/wiredscience/2008/09/the-bosons-that.html)

Quote
The Big Bang Theory

Best Case: The Large Hadron Colliders' ALICE experiment successfully creates quark-gluon plasma, a substance theorized to have existed just milliseconds after the Big Bang. By generating temperatures more than 100,000 times hotter than the sun, scientists hope to watch as this particle goo cools and expands into the particles that we know. That could help scientists answer why protons and neutrons weigh 100 times more than the quarks they're made of.

Worst Case: Scientists inadvertently make a micro black hole, and the earth is quickly erased from existence. Just kidding: scientists at CERN and elsewhere have ruled out the possibility that the LHC will create any kind of doomsday scenario. The black holes that the LHC could theoretically create don't even have enough energy to light up a light bulb. On the other hand, the U.K.'s Astronomer Royal put the odds of destroying the world at 1 in 50 million (which puts it in the realm of possibilities but still not as likely as hitting the lottery).

String Theory

Best Case: Scientists detect certain types of supersymmetric particles, aka sparticles, which physicist Michio Kaku calls, "signals from the 11th dimension." This would show that string theorists have been on the right path and that the universe really is made up of the four dimensions we experience and then seven others that unite the forces of nature.

Worst Case: String theory's basic assumptions are violated. The LHC will be the first particle accelerator capable of allowing scientists to study W bosons, the elementary particle responsible for the  weak force. If they don't scatter in certain ways, it'll be back to the drawing board for a generation of string theorists, or as one physicist told New Scientist, "If we see these violations, people will start working very feverishly on some sort of alternative that will produce these violations."

The "Our Universe Is Not Alone" Theory

Best Case: If scientists find a long-lived gluino, the postulated supersymmetric partner of the gluon, one group of scientists argues that it can be seen as a "messenger from the multiverse" and will lend support to the theory that our universe is just one of many. (Keep in mind though: not everyone is buying this interpretation.)

Worst Case: Our universe really is alone. Or even worse: it's lonely.

The Dark Matter of the Universe Theory

Best Case: Astrophysicists currently believe that 96 percent of the universe is made up of dark matter and energy that we can't see and can barely detect. Dark matter alone is estimated to compose 26 percent of the universe, only we have no idea what it's made of. It has been postulated that the neutralino is the best candidate for dark matter. Many physicists hope that the neutralino -- which, if it exists, will be relatively easy to produce -- will make an appearance in the debris inside the CMS or Atlas detectors, confirming the theory of dark matter.

Worst Case: Proudly, physicists announce that they've observed dark matter's unmistakable signature inside one of the LHC's detectors. But over the next few weeks, the reality sinks in that they've actually made a measurement mistake. Some physicists don't think that the LHC will be precise enough to measure any dark matter that it's lucky enough to create.

The Standard Model of Particle Physics

Best Case: With the standard model so well elucidated, perhaps a curveball is in order. Sean Carroll of Cosmic Variance notes, "There is almost a guarantee that the Higgs exists, or at least some sort of Higgs-like particle," so perhaps the best scenario would be finding the Higgs-like particle rather than the Higgs itself. That wouldn't be such a radical break from the model such that all previous work is too highly devalued, and at the same time it could open new physics frontiers.

Worst Case: The Higgs boson -- the long-postulated particle that is supposed to give mass to particles -- is finally confirmed. Sure, discovering the Higgs at the LHC would be neat, but it would basically just confirm a lot of what physicists already know, without really pushing the science: Boring. Some scientists have even said that their worst case scenario for the entire collider project would be finding the Higgs and just the Higgs.

Particle physics is complicated. Tweets are not. So, naturally, answering your questions about the Large Hadron Collider in Twitter format, i.e. 140 characters or less, could help you understand some physics.

Q: WTF is a Large Hadron Collider?
A: Hadrons are the parent family for protons and neutrons. The collider will smash protons together to see what they're made of.

Q: What are ATLAS and CMS and all these other acronyms?
A: They are particle detectors. ATLAS and CMS are the big ones. Each detector is designed to carry out a set of experiments.

Q: How does the Large Hadron Collider work?
A: It smashes particles moving at near the speed of light together. Then, detectors look for very rare particles in the wreckage.

Q: Is smashing things together to look for progressively smaller and rarer particles really how particle physics is done?
A: More or less: yes. Theoretical physicists work out the math. The experiments get run to see whose math matches the world.

Q: Gimme the stats on the Collider? Factoid stats.
A: 17 miles around. 9,000 magnets. 7,000 scientists. $10 billion. Operating temp: -456.25 F. Power used: 120 MW. Network: 1.8+Gb/s.

Q: Who paid for the Large Hadron Collider?
A: You did! But not nearly as much as your European cousins. The US contribution stands at $531 million. Total cost: $10 billion.

Q: How does a particle detector work?
A: They work like digital cameras with 150 megapixels taking snapshots 600 million times a second! Then algorithms look for interesting stuff.

Q: Is there an end 'product/goal' that the average Joe will eventually see from these experiments? ie:teleportation?
A: Not directly, but confirmation that physicists understand the universe would be nice. And you never know. The engineering can lead to other things.

Q: When you smash particles at nearly the speed of light isn't that going to release a lot of energy?
A: Yes. The highest-energy collisions will reach 14 trillion electron volts.

Q: How many particles are actually colliding?
A: Hacked Wikipedia: The beam pipes contain 1.0×10-9 grams of hydrogen, which
would fill the volume of one grain of fine sand.

Q: Is the Large Hadron Collider a threat to human civilization and the existence of the Earth?
A: No. Einstein's relativity says it's impossible. And, just in case, studies of highly-energetic cosmic rays hitting earth rule it out, too.

My friend is worried about a "Big Bang" that might be caused by it.  He's afraid it'll explode.  I have no idea how to yell at him and call him stupid while being smart.  Any ideas?
If your friend is afraid of the LHC experiments, then he should be constantly living in fear.  Collisions of this energy and higher happen in nature every day.  The universe has already run "experiments" of this kind so many times it has to be shown in scientific notion and I forget what order of magnitude it gets into.

It is interesting to think about.  What would it be like if a black hole was created?  Some say that if the mini-black holes didn't evaporate as Hawkings says they should, that they would take thousands of years to engulf the earth.   Even those that disagree say it could take years or decades to finish the job.
