You'll recall a few years ago MY PARTICLE was allegedly found by CERN.
Now, after several years of tweaking, CERN is prepared, inter alia, to
study ME further.
"By providing collisions at energies never reached in a particle
accelerator before, the LHC will open a new window for potential
discovery, allowing further studies on the Higgs boson and potentially
addressing unsolved mysteries such as dark matter. The ordinary matter
of which we, and everything visible in the universe is composed, makes
up just 5% of what the universe is made of. The remainder is dark matter
and energy, so the stakes for LHC run 2 are high."
You can have the 95% mysterious stuff. I'll stick with the 5%.
