Light Sabers Becoming A Reality?
A beam of light is supposed to shine off into infinity, but when Darth Vader and Luke Skywalker whip out their lightsabers for some spark-flying action, the light blades extrude like stick deodorant and then just stop. It’s like they’re sticks of light-matter. Hollywood may have made that stuff up, but now scientists at MIT and Harvard have actually made that stuff — not enough for a lightsaber, only a subatomic smidgeon. If we ever get the full sabers, I shudder to think of their users. Will people take them to discos instead of glow sticks?
