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

    Looks like I am light years away from joining the ackchyually club.

      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 the speed of itself!

      “Ackchyually” indeed, LOL

      Does not make it “not the speed of light”, only not c. Also the laser would fire particles with the speed of c if fired in a vacuum.

      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.
