MOBILITY

, an aptitude or facility to be moved.

The Mobility of Mercury is owing to the smallness and sphericity of its particles; and these also render its sixation so difficult.

The hypothesis of the Mobility of the earth is the most plausible, and is universally admitted by the later astronomers.

Pope Paul V. appointed commissioners to examine the opinion of Copernicus touching the Mobility of the earth. The result of their enquiry was, a prohibition to assert, not that the Mobility was possible, but that it was really true: that is, they allowed the Mobility of the earth to be held as an hypothesis, which gives an easy and sensible solution of the phenomena of the heavenly motions; but forbade the Mobility of the earth to be maintained as a thesis, or real effective thing; because they conceived it contrary to Scripture.
