Recently a new type of gravitational coupling due to a gravo-inductive
force field generated by mass currents was introduced to account for
constant rotation velocities at large distances from galactic cores. I
t is pointed out that the exact analogy with electromagnetism assumed
in postulating this force would for reason of consistency imply a vani
shingly small coupling rather than the anomalously large coupling requ
ired. The gravo-inductive radiation is compared with gravitational rad
iation for its role in the damping of the motion of bound systems.
