minus-square@[email protected]linkfedilinkEnglish250•2 months agoIt’d be impressive if they fire it at like half the speed of light
minus-square@[email protected]linkfedilinkEnglish75•2 months agoI mean, any other non-c speed really.
minus-square@GlowsticklinkEnglish102•2 months agoActually, 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.
minus-square@Bassman1805linkEnglish56•2 months ago(For anyone curious, the speed of light in earth air is like 99.97% as fast as in vacuum)
minus-square@[email protected]linkfedilinkEnglish15•2 months agoYou’re in science_memes what did you expected?
minus-square@5oap10116linkEnglish34•2 months agoDo you know what the religious affiliation of these space lasers will be?
minus-square@dohpaz42linkEnglish21•2 months agoYou have a lot of chutzpah to ask such a question. Oy! What would your mother say?

minus-square@marcoslinkEnglish7•2 months agoA 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.
minus-square@[email protected]linkfedilinkEnglish1•2 months agoI’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?
minus-squareTlaloc_TemporallinkfedilinkEnglish6•2 months agoMuch 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.
minus-square@[email protected]linkfedilinkEnglish14•2 months agoI would be especially interested in speeds larger than c 🙂
minus-squareLadlinkfedilinkEnglish18•2 months agoImagine if they made it fire so slow that you could just do a dark souls dodge roll to avoid it
minus-square@[email protected]linkfedilinkEnglish9•2 months agoWould you accept 10,000 times slower than the speed of light?
minus-square@[email protected]linkfedilinkEnglish6•edit-22 months agojust shine a laser through a thing of zircon (n=index of refraction=1.923~2) so speed of the laser in the zircon = c/n ~c/2

Bunch of nerds in this thread.
You’re in science_memes what did you expected?
hot science girls
Where?
In your area
exactly where they should be.
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?

Still too fast to dodge.
Pffft. Amateur.
