Publicly available data from well calibrated scientific instruments is the best way to make progress about the nature of UAPs. Notions are easy to float if they are not supported by detailed data. The equations derived here apply to any level of acceleration or velocity in 3D space. We have no experimental evidence for additional dimensions of space.

Gravitational sensing requires the next generation of interferometers in space. I already considered that in previous work. The current sensitivity of LIGO, for example, can only detect objects with a mass of a hundred thousand tons moving near the speed of light.
