It's hardly for the first time, though. Admittedly this is the highest energy but the 13 TeV headline figure disguises a couple of points: rarely, if ever, will any one collision contain more than a fraction of that energy, so in fact much of what goes on is often at the sub-TeV level (which has been done before). This is why you needed an 8 TeV machine to find a 125GeV (ie about 1/60 of the input energy) particle in the Higgs boson. Similar-energy collisions have taken place previously, at the Tevatron in the USA for example, and while the LHC delivers more of a punch and should give access to some new physics, it's in a similar ballpark really.
And then the other point is that already higher-energy collisions take place naturally anyway, in the form of cosmic rays. Although typical cosmic ray energies are lower than what we can now produce in the lab, a handful of events have been observed producing effective energies 50 times higher than anything in the LHC to date. If such a collision would rip a hole in the Universe, it would have already happened. But it hasn't and it won't.
There is exactly nothing of substance in either of matrixneo's posts -- I dare say most people knew this already, really. Still, it remains kind of exciting to feel part of an international conspiracy.
