  Gravimeters[1] are an incredibly cool technology. I'm given to understand that the most sensitive ones can actually track a person moving around the room it's in. [1] https://en.wikipedia.org/wiki/Gravimeter https://en.wikipedia.org/wiki/Gravimeter

    Yeah, and there's no known way to shield gravity so such a detector can see though walls.

      You just need another person doing an offsetting walk on the opposite side of the sensor.

      Not even by putting something of identical mass on other side of the detector? Alternatively you could slow yourself down to absolute zero velocity such that you are no longer travelling through space, only time.
