People say that nothing else in the Universe can go faster than the speed of light, as the energy used would drastically increase to move something with mass that fast. But light has mass, so how come it can move that fast?

Ah, but there is a force or energy that can go faster than the speed of light...
it just hasn't been discovered yet.

Light is made up of photons, according to the corpuscular theory of light. By definition, photons have no mass and move with speed c.

A little bit of a flawed statement there. Light is composed of photos. Photons are massless particles, or if you want to put the theory in context, they have relativistic mass... which is a concept better explained in the link below:

Light doesn't have mass. Yes it has particle like properties but that doesn't mean it has a mass. I think it's now believe that light emits photons?

Nothing with mass can go faster than (or even as fast as) the speed of light, as you say.
But light has no mass (contrary to what you say), so it can go as fast as the speed of light.

ahhh, grasshopper, but there is that which is faster than the speed of light, however the discovery is in the journey...
