I watched some technical video the other day about a quantum guidance system and for a brief second I thought it might be a flat earther conspiracy because a handful of the field specific jargon in the beginning sounded made up.
Is that the quantum gravity detection thing? Basically a way to map the entire gravitational field of earth giving each 3D space a unique position without the need for GPS?
The specific one I was watching was just talking about dead reckoning based on the same principle, but mapping seems like it could be a natural next step for the tech.
