  The universality of semiclassical gravity is investigated by considering the
behavior of the quantities < \phi^2 > and < {T^a}_b >, along with quantum
corrections to the effective Newtonian potential in the far field limits of
static spherically symmetric objects ranging from stars in the weak field
Newtonian limit to black holes. For scalar fields it is shown that when
differences occur they all result from the behavior of a single mode with zero
frequency and angular momentum and are thus due to a combination of infrared
and s-wave effects. An intriguing combination of similarities and differences
between the extreme cases of a Schwarzschild black hole and a star in the weak
field Newtonian limit is explained.
