Dodging lasers? Turns out, yeah its kinda possible, but by the time its possible, the lasers would be too diffuse to do any damage and couldnt be targeted accurately enough anyways.

Hope you had almost as much fun watching this as I had making it :-)

Plus I always like the light speed flyby of Earth.... really helps to put things into perspective!

Can you dodge Space Lasers?

Laser beams have been a staple weapon in scifi for decades... but can you dodge space lasers! Well, maybe, if you could see them coming... unfortunately in space... noone can see lasers coming! Probably the best trek episode ever. In the Pale Moonlight https://www.youtube.com/watch?v=StF9jrhw-pU support this channel: https://www.patreon.com/Thunderf00t

Thanks Thunderf00t for everything you do and loved your breakdown of lasers. I love Sci-Fi shows as long as I don’t have to struggle with squelching my understanding of physics long enough to enjoy the plot. Otherwise such films become a criticism frenzy of ridiculousness. I always found Babylon 5’s lasers to be slightly more consistent than other shows with regards to laser fire as one constant beam going off to infinity rather than the relatively slow moving bolt that one could watch passing by. From the observer’s point of view, at least when it comes to short distances, the beam is either on or off. Everything changes of course when it comes to long distances like from the Earth to the moon and greater. Hard to beat Spaceballs though… can you explain the physics of “going plaid”?

Cool video! Last I heard about laser weapons in space was that the concept was to push remote objects to affect their orbits. Slow down an object and it comes barreling down the gravity well. How much energy would a laser need to pump to, say, deorbit a human within a reasonable amount of time? I imagine it'd melt the human, of course. What about a typical spaceship in various sci-fi shows? How much orbit deformation would occur if the spaceship is absorbing the energy? How much would occur if it's reflecting the energy?
