    it’s not. Light only travels at c in a vacuum.

      If you really want to be pedantic, c is the notation for the “speed of light in a vacuum”, not just the “speed of light”, which depends on the medium.

        Which is what I was going for. But as flughoernchen already said, it can.

        Now we just have to bring that laser into space. Or shoot into outer space. An idea so cool, I’m disappointed I didn’t think of it.

      But it’s a laser. However fast it’s going, it’s going of the speed of light (i.e. itself)!

      “Ackchyually” indeed, LOL

      Does not make it “not the speed of light”, only not c.

      Headline says that it can fire at the speed of light though not that it does.

      I am being pedantic here, but if the laser travel at the same speed as c in a given medium, then it is going at the speed of light.
