Yesterday the Nobel Prize was awarded to Canadian physicist Arthur B. McDonald and Japanese physicist Takaaki Kajita, “for the discovery of neutrino oscillations, which shows that neutrinos have mass.
What is the actual significance of Neutrinos?
Solar neutrinos could shed light on the inner workings of our sun and other stars, because they don’t interact much with other particles as they travel from the sun’s core out into space. (Isaac Asimov dubbed them “ghost particles.”) So the information they carry is less warped by interference. Neutrinos may also provide clues about the nature of dark matter( here the link for my article on Dark matter) and dark energy—two of the biggest challenges facing physics in the 21st century.
So, what actually are Neutrinos?
Neutrinos are tiny subatomic particles that move at nearly the speed of light and pass through almost anything without effect. To detect just a handful of the billions streaming through Earth at any given moment, scientists have built giant underground tanks, filled with tons of water and shielded from any other radiation. On the rare occasion that a neutrino strikes an atom’s nucleus, the collision produces a dim streak of light that contains information about its energy and the direction it’s traveling.
So, this was a brief look at the neutrinos… Let me know what do you think?
