What is light exactly? we don’t actually know. How does light move? During the last period, it was pretty well supposed that light was a wave marvel that needed a medium “The ether” in order to spread from one place to another. It was supposed of as some odd kind of water upsurge.

Then a series of famous trials proved that the ether didn’t exist, so physicists had to re-think what the indispensable nature of light was. The best understanding, we have is that it is a trouble in the electromagnetic fields of emotional bodies.

Light is calm of particles called photons. Each photon is a discrete pack of electromagnetic energy that voyages at 299792458 m/s, which is the haste of light. The packs carry no mass, but they do have an real mass that is determined by the vigor. They carry respects of Einstein’s famous E = mc2.

Now according to some philosophers, if ever there will be a fight amid Light and darkness, then clearly the darkness would win since light requires photon energy so it has to run out at some point. So dark means the nonappearance of light. In other words, when there was nothing, it was the dark that exists, and also at the end of time dark will be the final victor.
