It'd be impressive if they fire it at like half the speed of light

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)

Bunch of nerds in this thread.

You're in science_memes what did you expected?

[–] [email protected] 2 points 3 months ago (1 children)

hot science girls

[–] [email protected] 1 points 3 months ago (1 children)

Where?

[–] [email protected] 3 points 3 months ago

In your area

[–] [email protected] 1 points 3 months ago

exactly where they should be.

Maybe it's going to be space lasers.

[–] [email protected] 1 points 3 months ago

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

[–] [email protected] 0 points 3 months ago (1 children)

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.

[–] [email protected] 0 points 3 months ago (1 children)

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?

[–] [email protected] 1 points 3 months ago

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.

Would you accept 10,000 times slower than the speed of light?

[–] [email protected] 0 points 3 months ago (1 children)

Still too fast to dodge.

Pffft. Amateur.
