Will the Mystery of Dark Matter be Unlocked in 2012?

There’s another reason to watch what happens in 2012: Neutrino mass will be measured by The Karlsruhe Tritium Neutrino Experiment in Germany, in the quest for the missing link to understanding dark matter, the undetectable matter (so far) that makes up about 25 per cent of the matter in our universe.
There are many theories of what dark matter consists of. We do know that around twenty to twenty-five per cent of all matter is dark, while less than one per cent emits light. The current paradigm is that of ‘cold’ dark matter: heavy particles that were already collecting together before the primordial plasma turned into hydrogen and helium. These would then move towards the collections of dark matter, which explains the current structures of galaxies and clusters. However, despite many attempts, the particle in question has never been identified.
In a recent report, physicist Theo M. Nieuwenhuizen suggests that neutrinos could be the missing link. Neutrinos are uncharged particles, such as those created during the nuclear fusion processes in the sun. Their role in ‘cold’ dark matter is considered to be negligible, partly because the neutrino mass has never been determined. Nieuwenhuizen now concludes that this is indeed light, but not super-light: 1.5 electron volts or three millionths of the electron mass. He obtained this information by studying data from a cluster of galaxies, where there is a great deal of dark matter present, as well as a large amount of hot gas. Nieuwenhuizen formulated a new theory for this purpose, based on Newton’s laws and quantum mechanics, but also virial equilibrium (a state in which all speeds are approximately the same). He then used this theory to determine the mass of the dark matter particle and even the temperature of the gas. The dark matter forms a quantum structure in the centre of the cluster that is a couple of light years in diameter: the largest known.
Up until a few years ago, it was believed that neutrinos were left-handed (like a top that spins to the left), and that anti-neutrinos were only right-handed. This theory leads to 9.5 percent dark matter; much more than is anticipated from neutrinos, but less than the estimated twenty to twenty-five per cent. It is possible to explain twice as much dark matter if right-handed neutrinos and left-handed antineutrinos are also normally present. However, this assumption requires changes to be made to the standard model of elementary particles. The lepton number (an indication of the number of subatomic, elementary particles) is therefore violated. This means that it must be possible for two neutrons to disappear simultaneously without the release of neutrinos. This therefore leads to nineteen per cent ‘hot’ dark matter and also the need for a new explanation for structure formation in the early universe. A definite answer on the theory will be obtained in 2012, when neutrino mass will be measured by The Karlsruhe Tritium Neutrino Experiment in Germany.

In a conversation recorded in 2007, artist Hiro Yamagata questioned what else the neutrino may carry:
We base everything we think, capture thought in 3D. There is something we call zone, area, territory, or another world or this other world we talk about so many things explain, but we don’t know. For example neutrino, the most weakest power from the edge of the cosmos. They go through Earth to the edge of the cosmos. They journey, travel. The neutrino is the most weakest power and their frequency travel. But the neutrino particles we know people capture now the neutrino. Might neutrino carry something else with each particle, for example? We don’t know. We call the focus of neutrino here. Now we capture the neutrino, but not only neutrino. There’s a neutrino carry something else together, stick on, or time-wise, field-wise, we don’t know where the neutrino come, how it comes through your body. We don’t know. Just basic we capture it now, the neutrino now, but we don’t know. 2.7% we know about light. 99% we don’t know what’s going on the light or all the knowledge of the light. How they put on the 2.7%, even that number we don’t know. So there are so many where light come from: original light, meta particle, or proton between the electron; one of the particle of the electron, they are hitting the light and releasing like gravity, they come to light. All light like that.
