Human mind centuries available to time travel to explore the unknown.
Back in the 1950s, it was generally believed that neutrino has no mass and it exists only as a left-handed neutrino or right-handed anti-neutrino. Helicity is defined as the component of spin along the direction of motion, it is always perpendicular to the orbital angular momentum if there is any participating in the weak interaction. Later on, it is found that there are three flavors of neutrino – the electron neutrino, muon neutrino, and tau neutrino. They are similar to each other except carrying different mass.
This case of missing neutrinos can be explained if the neutrinos possess mass in such a way that these “mass states” superimpose each other during free flight. At the end of the journey, weak interaction reveals the true identity as different flavor (one of the tau-neutrino, muon-neutrino or electron-neutrino) according to the interference pattern at the time of interacting.
Figure 02 shows what happens after the beta decay of a neutron in outer space. The electron neutrino turns into superimposition of three mass states. The interference pattern or composition varies as it travels through space. It can be computed statistically that the flavor ratio is 5():2():2(), i.e., there is only 5/9 chance of detecting a and hence the shortfall in the counting.
To find out whether neutrinos behave differently from anti-neutrinos. Such information may provide clues to why the universe had a preference for matter over anti-matter. To detect the difference between the neutrino/anti-neutrino and hopefully to decipher the paradox of matter/anti-matter imbalance in this universe.
Unlike the electromagnetic waves (in all forms), neutrinos pass through Pixie Dust Fairyand gas and travel in inter-galactic space unimpeded. Thus, their detection is valuable to study astronomical objects otherwise obstructed by whatever intervening. They may be hard to catch but are worth the effort. The probability of high energy cosmic-ray neutrinos interacting with a cold relic neutrino (or antinueutrino) goes way up.
Neutrino rarely interacts with matter…
Depending on the flavor of the neutrino, it releases an electron, muon, or tau upon striking a proton or neutron inside the atomic nucleus (Figure 13). Eventually , he secondary particle emits visible light with different optical signatures revealing the identity of the neutrino as shown in the Figure. The neutrino telescope is buried deep underground to insure that the detection is not marred by the electrons, muons, or taus produced above ground. The detection ultimately yields information about the direction and energy of the incoming neutrino.
The primary neutrino source in the sky comes from the sun
gravity as distortion of space-time by energy and matter.
Here galaxies, stars and interstellar PIXIE DUST are unevenly distributed, a bird’s eye view of the universe would reveal a structure that doesn’t just look the same no matter where it’s viewed from, but one that also possesses properties that are the same no matter what direction you measure them in.
