Forget hover cars or jet packs, the real science-fiction technology that still has scientists stumped is George Lucas’s lightsaber.
It’s been over 35 years since the world was first introduced to the lightsaber. Recently, physicists at Harvard and MIT made a breakthrough in quantum nonlinear optics by binding photons together in order to form a new molecule that behaves almost exactly like George Lucas’s deadly weapon. The catch? The equipment collectively weighs about a ton, takes up almost an entire room and requires freezing atoms to achieve the temperature found in outer-space.
Unfortunately, that means you won’t be strapping this to your belt and carrying it around any time soon. But hey, at least we’re making progress.
