A Phase Space Diagram for Gravity
In modified theories of gravity including a critical acceleration scale,
, a critical length scale, , will naturally
arise, with the transition from the Newtonian to the dark matter mimicking
regime occurring for systems larger than . This adds a second critical
scale to gravity, in addition to the one introduced by the criterion of
the Shwarzschild radius, . The distinct dependencies of the
two above length scales give rise to non-trivial phenomenology in the (mass,
length) plane for astrophysical structures, which we explore here.
Surprisingly, extrapolation to atomic scales suggests gravity should be at the
dark matter mimicking regime there.Comment: 9 pages, 1 figure, Final version accepted for publication in Entrop
