Is it theoretically possible for science to someday create a real lightsaber?
Alas, young Skywalker, are the ready-made signature lightsabers and DIY varieties not satisfying enough for your role-playing entertainment? As tantalizing an idea as a fully functioning lightsaber might be, there are critical physics hurdles that even the most brilliant imaginations can’t overcome — first and foremost being the nature of light. Assuming your lightsaber would incorporate a kind of laser beam technology, could the saber have a tip, since light waves don’t just stop but keep going? Such a device is more likely to bore a hole through the living room furniture than function like a luminous sword. There’s a quandary.
