CERN: Recreating The Big Bang

Mapping the Secrets of the Universe: ATLAS is a particle physics experiment at the Large Hadron Collider at CERN. The ATLAS detector is searching for new discoveries in the head-on collisions of protons of extraordinarily high energy. ATLAS will learn about the basic forces that have shaped our Universe since the beginning of time and that will determine its fate. Among the possible unknowns are the origin of mass, extra dimensions of space, unification of fundamental forces, and evidence for dark matter candidates in the Universe.

ATLAS is one of two general-purpose detectors at the LHC. It will investigate a wide range of physics, including the search for the Higgs boson, extra dimensions, and particles that could make up dark matter. ATLAS will record sets of measurements on the particles created in collisions - their paths, energies, and their identities.

This is accomplished in ATLAS through six different detecting subsystems that identify particles and measure their momentum and energy. Another vital element of ATLAS is the huge magnet system that bends the paths of charged particles for momentum measurement.

The interactions in the ATLAS detectors will create an enormous dataflow. To digest these data, ATLAS needs a very advanced trigger and data acquisition system, and a large computing system. More than 2900 scientists from 172 institutes in 37 countries work on the ATLAS experiment.

There's a big amount of irony in 'recreating the big bang'. The main scientific argue in it lies that its just a big bang and there's no deity in creating us.
So even if it works out as they thought it would, the main cause and reason for it would be cause something in this case someone intelligent set it all in motion.

Enough can't be said about how wonderfully revealing and explanatory the graphics in this video are. Much thanks to all!

[NicosMind]

This is one of my favorite episodes if not my favorite from NewScientist in the longest time. I just love this stuff :)

Hail science, the trustworthy process of explaining our universe and ourselves, removing bias, superstition and opinion and getting to the truth.

[DoubleEyeDominance]

it was good, but too short in my opinion. The cgi was good and entertaining, but still; a little longer would have been great.

@QIQrrr
The question is not loaded at all since it refers to observable, testable facts...

[lilsorms]

I was reading some forums that had thought experiment questions relating to how crazy things get at extreme speeds / distances, think light years.

Consider this one: You're holding a rigid pole 1 light year long. And you spin around once, your feet go from pointing due north around and back to due north. It takes you 10 seconds to do this. Does the tip of the pole exceed the speed of light in making the revolution?

@QIQrrr
The BB does not suggest creation ex nihilo, neither does it violate the principle of conservation of energy.

Cavitation in a liquid sphere demostrates how the big bang is possible. Gravity is probably the same princible as liquid dynamics. Our universe is a cavitated bubble within a body of some kind of density.

Can you imagine how far we could be right now had we not wasted so much money and resources on war instead of science?

[philowenify]

Phil Owen here, the guy who made the video. Thanks for the upload, added music and all the great comments! Sorry for my terrible narration, makes me cringe as well, was a rushed job with a few days of no sleep, ;{ Makes me really respect pro narrators after this.

@QIQrrr
It is quite likely there. Its indirectly observable. This makes theorists who would like to wish it away very nervous. This is actually the reason why none of those "fringe theories" are taken seriously at the present.

@sfg911
you seem to misunderstand the difference between theory and fact, the effect of Gravity is fact, the idea of how it works is theory. We can say that we know if we drop a ball it will fall, but we can say we currently believe that the reason for this is that all mass distorts spacetime causing the effect.

Full on Big Bang across the universe. It's so bright, so vivid... OMG, it almost looks like a triple Big Bang... What does this mean!

[imyyzu]

@zapo147 True, Gamma rays are emitted from near the poles but we still can't 'see' the black hole. The gamma ray beams are generated by collisions of the material falling toward the black hole. They are an effect of the gravitational forces we can observe like lensing of light and orbiting stars, not the black hole itself.

[evilmurderproduction]

@teemuruskeepaa you can trace the universe back to a single point by mapping the direction and velocity of any 2 objects that have separate paths of projection. It's the same principal as determining the origin of a gun shot based on angle and projection.

[thinkofwhy]

On second thought, you guys are right. She should keep the videos to 30 seconds. After that her directing goes offtrack and the plot falls apart, crashes and burns. My bad.

[Anonymoose]

What I will forever wonder is: what was *before* the Big Bang? It wasn't "nothing." It was "something." A completely collapsed previous Universe?

Infinity gives me

@QIQrrr
Facts as redshift, CMB, standard candles, (well tested model in) high energy particle physics, space curvature, gravitational lensing, etc. Even the very basic assumptions of general relativity were tested to be very likely correct. See e.g. the GRB 090510 supernova test.

Of course you can deny all this. But so what? You could even deny the train that would potentially hit you and smash you into smithereens. Why wouldnt we arrange a little demo? You will perhaps eagerly volunteer.

[rationalmuscle]

@QIQrrr Well, you don't have to... sure. But it would help to avoid saying the CBR does not support BB cosmology when it clearly does. If there IS another explanation we don't have one yet, but the one we 'have' fits perfectly with the past 100 or so years of science.
