Death by light saber - YouTube video

[scottdave]

I came across this YouTube video describing some of the "science" behind light sabers, and what it would be like to be hit with one. I thought it was worth sharing.

Next to "Tags," don't you see a "Add Tags" link?

Thanks, I found it.

I think "worse" should be changed to "dramatic". In the video it sounds like light saber hits would result in an instant and painless death depending on where you got hit. Compared to being cut in half by a broad sword.

Come on, this is not really scientific in the same way as trying to build a car or plane out of bricks and clay.

I think his assumptions at 1:15 and 1:30 are wrong. The light saber has an extremely sharp cutting cutting edge. The glowing plasma is molecules that have been cut into smaller pieces. The glow and cauterizing is just from energy released by the ions as they recombine.

Also by conservation of energy the light saber draws energy out of the surroundings. The rest of the room would feel colder in direct proportion to the energy needed to separate molecules at the edge of the blade.

How do you constrain plasma into a sword-like shape like ICRT does and generate enough power like a nuclear sub with a handle?the handle itself is the most powerful object in the universe alone, even more powerful than Death Star considering its size.

Don't know about light sabres but did come across a tale many years ago in which the protagonist used a molecular thin cord as a weapon.
The idea was to fix it across doorway etc, so that when the "baddies' came in it would slice them to bits. Had to have special gloves to handle it though! Neat idea for a booby trap! would have to remember to take it down though.

Spiders have been laying thin threads across access paths for ages, but the thread always seems to break when a large animal comes lumbering through.
Out of necessity for capturing prey, they instead opted for the next best, a web, and catch small insects.

Hmm, perhaps you have not seen Resident Evil . . . ;)
