No, light is not the fastest travelling thing in this universe and quantum entanglement fully supports my openion. It is interesting to note that every light sorce converges to a point source as we move away from it. So calling light the fastest is an old perspective in this modern world. Quantum entanglement is one of the central principle of quantum physics, which means multiple particles are linked together in a way that the measurement of one particle quantum state determines the possible quantum of the other particles and this manipulation of information takes place at a speed which is much more faster than the speed of light.
