scientists believe that dark matter / energy is the main ingredient of the universe. Until today they were unable to find it, though. Now, the folks at CERN try to find this mysterious matter with their LHC (Large Hadron Collider). But if they are successful this discovery could also mean the end of the world.

no. em radiation is only made of photons which have no mass at all. by your theory, anything that has energy has mass. so if an object is placed on a shelf 1 meter above the surface of the earth, its mass is equal to the potential energy over the speed of light squared. E=M/c^2 is only used in nuclear decay to determine the energy created by the mass lost in a nuclear reaction
if you look at an earlier post from me you see that I wrote photons have no REST mass, i.e. if photons would rest instead of travelling at the speed of light they would have no mass. But they don't, they always travel (in vacuum) with c.
No, before Big Bang were Dark Ages, and Dark Matter fills 96% of the modern universe. There are two major candidates for Dark Matter: strangelets and susy-particles (SUperSYmmetric).
The movie however is exaggregating some things.
1. It is not an objective to produce strangelets at LHC 2. One of the major goals is finding Higgs boson, which is also never seen before 3. Energy of collision is only 7 times greater than at RHIC (Fermilab)
re 1.: of course not, but it's not 100 % sure they could form 2. yes, the Higgs particle is supposed to give matter its mass / gravity, but it's only a hypothetical particle so far 3. yes, but this may suffice, somewhere could be a breaking point
@ Vassitch: thx for that comment. However, the RHIC reaches up to 250 GeV for protons (google it, can't post URL's). But this is still 28 x less than for the LHC. The most powerful accelerator so far, the Tevatron, reaches energies up to 1 TeV (hahajile meant that one). Anyway, the higher the energy the greater the danger. There could be a critical point just like there is a melting point and a boiling point for substances.
This would be a lot more convincing if it wasn't riddled with scare tactics. We wouldn't "feel something happening," it would be instantaneous, and the visuals of the earth exploding wouldn't take place because it would be an implosion happening. And all in all, it really just makes you question what happens when we cease to exist; it's not like this kind of thing would be painful. Things that are sucked into black holes move at the speed of light... I don't think it would hurt for very long.
no, it would not be instantaneous. It is predicted that radiation caused by the black hole inside Earth would kill all life before the actual implosion takes place. Furthermore the implosion scene IS indeed an implosion scene. No, things that are sucked into a BH are accelerated but they don't move at lightspeed. That would contradict Einstein's theory of relativity which states that matter cannot be accelerated to the speed of light unless the energy for that purpose was infinite.
If a black hole was created, how would radiation escape it to kill all life? Not even electromagnetic radiation which has no mass can escape a BH so how could anything else do so?
the radiation I was talking about is part of a theory that predicts it. However, I'm not certain where it would emerge (would have to dig deeper into that theory), I only know that they say it would be caused by the black hole (not necessarily emitted by it). To be more precise: electromagnetic radiation has no REST mass. Indeed it has an energy E=hv (where h is a constant and v the frequency). So you can calculate its corresponding mass by m=E/c² (c=light speed).

5 Gev on RHIC end 14 Tev on LHC
(5 000 000 000 VS 14 000 000 000 000)
