A Brief Idea of Time Cosmology-A question for all, what is time? ..In physics time is not a just a thing like 10am or 11am or due to the revolution of earth around the Sun. I will tell you, time is begin with mass and also end with mass, in this universe the energy have to converted in to mass effect causing particles because if the energy is not converted in to particles which have mass the time for itself is not start flowing Therefore for the flow of time the energy is converted in to a particles which have a mass. I have one of the powerful concept which prove above statements that is Photon it is expected that a photon have no mass but is not really true, photon also have mass ,the photon have to come in condition to have a mass because if it have no mass it is not able to come in universe, photon is that fundamental particle which have very very lowest mass in the universe ,we know great formula E=mc 2 but mass=E/c2,let energy-photon if it expected that is has no mass when it traveling with velocity(which is measured) its velocity become infinite and we are not able to measure ,It means that for a particle or energy for which time is flow it have to have a mass…At that time we find a particles which is excepted that a particles having mass greater than photon velocity that is Neutrino. from Albert Einstein concept tachyon particles having velocity greater than light, I have one great concept to think about it and that is the reason that something it is space fabric relate with mass having particles or it have to move in space time fabric to have a mass with respect to something, thus velocity in space time fabric produce a mass in a particles which is energy either positive or negative it is some kind different with five forces of nature which produce a mass that is Higgs boson particle in this whole endless universe not a particle present which have a mass with a rest velocity relative to space time fabric and that is the reason from the birth of universe(Bigbang) the whole universe is continuously expanding.
