[Star Wars] What would happen if a Jedi tried to use his lightsaber to block a physical round from a gun.
gpt
Assuming lightsabers work on the priciple of a tight superheated-plasma arc doubling over to create a physical 'sword' blade capable of reflecting other plasma expulsions and objects telekennetically launched at it as 'thrown' speed, as well as slice *slowly* through a metal door, it is most likely that a lead bullet, travelling at anything between 800-3000fps, *would pass through the blade so fast it would barely be lukewarm before it killed the unarmoured Jedi behind*.

Force or no-Force, a lightsaber would suck against solid metal high-velocity bullets, even if the Jedi was fast enough to precict where the bullet would hit them. At the very best they'd cut the bullet in half and just be hit by fragments instead.
