    Actually, c is the speed of light in a vacuum, but light travels slower through a medium, like air. So lasers shot through air will actually travel slower than c.

      (For anyone curious, the speed of light in earth air is like 99.97% as fast as in vacuum)

      A laser strong enough to be used as a weapon will probably not leave a lot of medium on its path.

      But the front-most part will still travel at less than c. It will just speed-up after a while.

        I’m curious. What happens to the medium? Does it simply get pushed aside? Or pushed along? Or will it eat up some energy and react to something else?

          Much like lightning, a powerful enough laser will ionize the air. That ionized air is hot and rises, just like the ionized gasses from combustion.

          A powerful laser will look like a beam of fire.
