Probably not, because the rate we'd decelerate the moon with our lasers would probably be slower than the speed it'd be traveling at towards us, and the time frame we'd have to try and decelerate it would be fairly short, (it'd take us longer for it to initially break free of our gravity well than it'd take for it to hit the earth after coming back into range of our lasers), so more than likely at best we could slow it down somewhat before it crashed into us. Of course, if it crashes into us at all, no matter how much we slowed it down, it and the earth both would be so heavily damaged that even if we somehow survived, we'd probably never be able to get it back of the earth.
It's helpful to know that, since people think "oh, I won't shine it in my eyes or anyone else's eyes, so I don't need goggles", that any minor reflective surface you happen to briefly shine upon can also cause instant blindness (or, at least, spots in your eyes that never go away for the rest of your life).
Laser Ablation is cool for other reasons. When I was a kid I had a genetic heart condition, I had (at the time) experimental laser ablation surgery to remove the fat cells that were growing in my right ventricle. Unfortunately it wasn't also enough power to send me into orbit
So you‘re telling me, if the Star Wars Deathstar were physics accurate, it would have just accelarated Alderaan gently away from itself (while still killing everyone on the Planet)? Dann that would have been way funnier. Just seeing it gently drift away with Vader just standing there like „we spent our entire Budget on THAT?“

@@raizin4908 Can't you theoretically use VR goggles in passthrough mode (or something similar to them) as eye protection? Especially against the wavelengths that are very hard to combat. Technically they're completely opaque, they just record video using the cameras and transmit it in real time to the screens. Yes, laser may permanently ruin the cameras, but I doubt it will have a chance to permanently ruin operator's eyes

Probably not, because the rate we'd decelerate the moon with our lasers would probably be slower than the speed it'd be traveling at towards us, and the time frame we'd have to try and decelerate it would be fairly short, (it'd take us longer for it to initially break free of our gravity well than it'd take for it to hit the earth after coming back into range of our lasers), so more than likely at best we could slow it down somewhat before it crashed into us.
