Supersymmetry predicts that versions of the particles that make up normal matter possess mirror or supersymmetrical versions. Thus there could be supersymmetrical quarks – or squarks – out there. Or supersymmetrical electrons – selectrons. “The trouble is that supersymmetry predicts that these entities exist but doesn’t say at what energies we might find them,” adds Charlton.
Nevertheless, Cern physicists believe supersymmetrical particles could lie within the range of the energetic collisions that will be generated in the upgraded LHC. And if they do detect these strange entities, they could provide the solution to one of the universe’s greatest mysteries: the nature of dark matter.
Dark matter is believed to pervade the cosmos, giving galaxies far greater masses than could be supplied by the “normal” matter of protons, neutrons and electrons. Its existence is only inferred, however, for despite decades of effort, scientists have yet to observe a single unit of dark matter. The new LHC could change that.
“The main candidate to explain dark matter is the Wimp – which stands for weakly interacting massive particle,” adds Charlton. “And it may turn out that Wimps are types of supersymmetrical particles that we will be able to make in the LHC.
So they are saying that they can't find dark matter.
By its very nature, dark matter hardly interacts with normal matter and so will not appear in our detectors. However, it will be noticeable as an event that has missing energy and momentum. In that way, we will know we have created dark matter.
Lol. That was the exact gist of my e mail to a female scientist there at lhc, even b4 they fired up this contraption for the first time

Sort of, but it explains that the LHC can't find dark matter which is what I already suspected. From the same source:

What they can do is notice if something is missing, then infer that the missing energy must be related to dark matter somehow.

The video in the post I replied to.
It´s really b#tery at its climax. Didn´t you notice that? Come on.
Where he fails to see that the blue and red lines rotating are ment to visualize how fast they circle the ring.
He says they get so much mass they do not fit there in anymore ^^ made me chuckle.
"Einstein warned us if we reach lightspeed that it would be the end of the universe" Is that so? Not really and it´s still a theory....
Somebody help me up off the floor, I just fell over. After all your denials of relativity, you and I actually agreed on something?

I haven't walked around recording everything Hawking ever said, but I doubt he said what that article claims, and it's basically bunk.

Is this centering around the same topic, and does the piece I linked have any validity to it?

It seems we already have an inference of dark matter via the galactic rotation curves, and gravitational lensing. So the LHC may also find more evidence of the existence of dark matter to add to that pile, but we already have quite a bit of evidence of dark matter so if they can't detect it, and they can't, then I don't know how helpful the "Hunt for Dark Matter Particles" can be when they say "'dark matter' will not appear in our detectors".

But mate. Dark matter cannot be gravitons. We are looking for particles with mass. Gravitons have no mass.
Unless I misunderstand you?
