To analyse the 1214 PBytes of data produced by the LHC experiments each year will need GHz CPUs We have a 560 CPU farm in this building with 100TBytes storage, connected to a globally-distributed network of computers. The UK particle physics Grid is run from Glasgow. Large open questions Why is the universe here at all? Why is the Universe made of matter and not equally of anti-matter? Where has all the anti-matter gone? Anti-matter The development of the Universe containing matter and no antimatter requires that matter and antimatter behave differently matter C Spatial mirror Make into Anti-Particle P Discovery of CP violation in the B-meson system at Stanford, 2001) A visible difference is detected, but tiny, not enough to explain the matter-antimatter asymmetry in the Universe Since the universe is here, where is all the rest of the matter? Dark Matter Visible Matter False-colour images The brightness of clumps corresponds to the densitydensity of mass. Can also help to unify forces WEAK STRONG GRAVITY ELECTRO- MAGNETIC UNIFIED FORCE? If two particles pass close enough with enough energy, they may form a black hole Black holes at the LHC For 3 spatial dimensions, this will never happen gravity is too weak. But with extra dimensions, gravity may become stronger, micro black holes can be created in particle collisions Another big question do we understand the geometry of spacetime?
