minus-squareGlowstick@lemmy.worldlinkfedilinkEnglisharrow-up105·1 year 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-squarejaybone@lemmy.worldlinkfedilinkEnglisharrow-up24·1 year agoBunch of nerds in this thread.
minus-squareVilian@lemmy.calinkfedilinkEnglisharrow-up15·1 year agoYou’re in science_memes what did you expected?
minus-squareASeriesOfPoorChoices@lemmy.worldlinkfedilinkEnglisharrow-up6·1 year agoexactly where they should be.
minus-squareLilDumpy@lemmy.worldlinkfedilinkEnglisharrow-up5·1 year agoYa, but that’s JUST slow enough to be able to see it.
minus-squareDannyBoy@sh.itjust.workslinkfedilinkEnglisharrow-up15·1 year agoMaybe it’s going to be space lasers.
minus-square5oap10116@lemmy.worldlinkfedilinkEnglisharrow-up34·1 year agoDo you know what the religious affiliation of these space lasers will be?
minus-squaredohpaz42@lemmy.worldlinkfedilinkEnglisharrow-up22·1 year agoYou have a lot of chutzpah to ask such a question. Oy! What would your mother say?

minus-squaremarcos@lemmy.worldlinkfedilinkEnglisharrow-up7·1 year 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-squaresinkingship@mander.xyzlinkfedilinkEnglisharrow-up1·1 year 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_Temporal@lemmy.calinkfedilinkEnglisharrow-up6·1 year 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-squareEril@feddit.orglinkfedilinkEnglisharrow-up15·1 year agoI would be especially interested in speeds larger than c 🙂
