The secret to faster-than-light physics could be to double down on the number of dimensions, according to new research published last month in the journal Classical and Quantum Gravity. Specifically, the solution may lie in three dimensions of time, with just one representing space. The math is deep and complicated, but the ideas may be within our grasp after all. And there’s one math trick at superspeeds that may just “flip” your lid.
The key idea at play here is that of a “superluminal observer.” “Superluminal” means faster than light, from super- meaning “more” or “most,” and -luminal like, well, Lumière from Beauty and the Beast, and the lumens that power your home movie projector. The superluminal observer is a hypothetical thing that is looking at the universe while traveling faster than light. It’s you in your Star Trek warp-speed shuttle.
Superluminal observers are cool because, in a way, they marry together two very different sides of physics: general relativity and quantum mechanics. General relativity is the work embodied by Albert Einstein, which governs how spacetime functions as bodies move around the universe at subluminal, or slower than light, speeds. Quantum mechanics explains how subatomic particles behave, or don’t behave, in very strange ways on the smallest of scales.
The research team—led by theoretical physicist Andrzej Dragan of the University of Warsaw and the National University of Singapore—has theorized that many parts of quantum physics, like indeterminism and superposition, can be explained if you take general relativity and apply its principles to the superluminal observer. In other words, how messy does spacetime get if we take our shuttle up to warp speed? Is everything suddenly in multiple places at once?
