4-5 orders of magnitude more sensitive?
Good luck, mate.
Real world geophysical gravity measurements are already noise limited by vertical differences of about 1cm (moving w.r.t. the center of mass of the Earth and measuring the mass of the whole planet).
Gradiometry is slightly better, but still. I say build such an instrument first, _then_ try to detect airplanes.
- causality0 6y agoExactly. I don't understand what's new in this paper. We've known for decades that since gravity is a force with unlimited range and information cannot be destroyed, you could work out the positions, masses, and motions of the entire earth and everything on it by monitoring a single object with enough precision and isolation.
- robscallsign 6y agoIt's non-unique - there are an infinite number of configurations of mass that could have cause that single object to move in exactly the way it was measured.
