These things are only about 4 GeV (4 times heavier than a proton, much lighter than the Higgs boson, much smaller than the energies in the LHC, an extremely easy energy for cosmic rays to reach). Neither energy nor density are keeping us safe if these things are dangerous—the LHC just detected them by making lots of them and having really good sensitivity.
Energetic perhaps. But as dense also?
