    if you're inside an elevator in freefall, there's no way to tell the difference between accelerating at 1.0 G at the earth's surface, or 0.01 G in the outer solar system, or 10.0 G through the clouds of Saturn.  All you know is there's nothing holding you up.  And if the weight inside an accelerometer is accelerating at the same rate as the frame of the accelerometer, it will read zero.

    the purpose of the second amendment is to promote a well-regulated militia, in the same sense that the purpose of the first amendment is to promote a well-informed electorate.

      I misinterpreted the scenario.  And I also forgot how they do gravity-mapping - by comparing the positions between two spacecraft.
