Why light travels fastest in the world??
Light travels so fast because it has no mass. The particles that make up electromagnetic radiation are called photons. Each photon has a packet or quantum of energy depending on the frequency of the radiation. The photon also has some momentum, but its mass is zero.
Anything that isn't light interacts with a field called the higgs field. This interaction with the higgs field “slows down” anything that has rest mass because of something called weak hypercharge exchange. In fact, it is exactly this phenomena, called the Higgs mechanism that gives everything that has mass it's mass.
Light does not interact with the higgs field the way other particles with mass do and therefore isn't “slowed down” and is free to travel at 299792458 m/s.
