Alice is a side project the LHC have been working on in conjuction with the "primordial soup" experiment.
Im interested to see how this works out. Go figure the majority of mass is undetectable (for now).
Physicists working on the ALICE experiment will study the properties, still largely unknown, of the state of matter called a quark-gluon plasma. This will help them understand more about the strong force and how it governs matter; the nature of the confinement of quarks – why quarks are confined in matter, such as protons; and how the Strong Force generates 98% of the mass of protons and neutrons.
The ALICE detector is placed in the LHC ring, some 300 feet (100 metres) underground, is 52 feet (16 metres) high, 85 feet (26 metres) long and weighs about 10,000 tons.
During collisions of lead nuclei, ALICE will record data to disk at a rate of 1.2 GBytes (two CDs) every second and will write over two PBytes (two million GBytes) of data to disk; this is equivalent to more than three million CDs (or a stack of CDs (without boxes) several miles high). To process these data, ALICE will need 50,000 top-of-the-range PCs, from all over the world, running 24 hours a day.
