  I will argue that the inertial mass is greater than the gravitational mass
for all objects which are held together primarily by gravitational forces.
Thus, for celestial objects, like planets, stars and galaxies, their inertial
mass is greater than their gravitational mass. The analysis used to arrive at
this conclusion shows that there should, in principle, exist classical objects
with non-zero inertial mass and vanishing gravitational mass. Implications for
Quantum Gravity and Quantum Cosmology, are briefly discussed.
