minus-squaremarcos@lemmy.worldlinkfedilinkEnglisharrow-up7·7 个月前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.
minus-squaresinkingship@mander.xyzlinkfedilinkEnglisharrow-up1·7 个月前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?
minus-squareTlaloc_Temporal@lemmy.calinkfedilinkEnglisharrow-up6·7 个月前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.

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?
