I mean, any other non-c speed really.

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)

Ya, but that’s JUST slow enough to be able to see it.

Maybe it’s going to be space lasers.

Do you know what the religious affiliation of these space lasers will be?

You have a lot of chutzpah to ask such a question. Oy! What would your mother say?

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.

I would be especially interested in speeds larger than c 🙂
