The neutrino is a tiny elementary particle, but it is not part of the atom. They exist in nature. Neutrino has a very tiny mass, no charge and spins half. It interacts very weakly with other matter particles so weakly that every second trillions of neutrinos fall on us and pass through our bodies unnoticed. ..
Normal lenses such as the ones used in a magnifying glass or a pair of spectacles bends the light rays that pass through them by refraction and focuses the light somewhere (such as in your eye). Gravitational lensing is among the first evidences of Albert Einstein’s general theory of relativity – simply put, mass bends light. The gravitational field of a massive ..

It has been generally assumed that neutrinos travel at the speed of light. According to the theory of relativity, if neutrinos are massless, they must travel at the speed of light. However, if they carry a mass, they cannot reach the speed of light. There have been various theories regarding the speed of Neutrinos. It ..
