We demonstrate that, by assuming that the gravitational force is decreasing faster than the inverse square, the galaxies are limited to a size that depends on the force law and mass‐density distribution. Specifically, for a gravitational force of the form K/[r2 exp(r/R)], the galaxy is limited to a radius smaller than R, but within the solar system the change is insignificant.
