Large Hadron Collider starts up again

CERN's newly upgraded atom smasher has now resumed operations after a two year hiatus.
Having successfully discovered the Higgs boson back in 2012, the Large Hadron Collider was shut down so that it could undergo an upgrade to double its maximum collision capacity.
Now capable of reaching power levels of up to 14 teraelectronvolts, the world's largest particle accelerator has begun a new mission to explore uncharted frontiers in particle physics and to unlock the secrets of dark matter, the theoretical substance thought to make up most of the mass in the universe.

"Today at 10:42 am (0842 GMT) a proton beam was back in the 27-kilometre (17-mile) ring, followed at 12:27 pm by a second beam rotating in the opposite direction," CERN said in a statement. "But the most important step is still to come when we increase the energy of the beams to new record levels."

Smash atoms ?..why don't they save themselves a lot of time and trouble and just use a hammer.

oh its ok there will be no black hole hears a joke to explain things a atom and atom ran at each other while telling jokes so just before they broke they started creaking up, and as for the creaking up its just natural that it splits some, so what happens when atoms split... (i never said that it was going to be a funny joke all i'm saying that if they smash in to each other they will probably just (in slo' mo) start to crack than split than go boom)

Woohoo finally. Hope they will discover lots of fancy things :-D

Smash atoms ?..why don't they save themselves a lot of time and trouble and just use a hammer. More like a pick axe I'm afraid. And the point would have to be very, well, pointy. Otherwise it wouldn't be able to deliver the force across a very small area to smash atoms. Much easer to use plasma beams instead, especially seeing as they don't blunt.

I'm hoping evidence is found for higher dimensions. That would help explain a lot of phenomenon, and maybe VRIs too.
