Attached to: Cosmologists Show Negative Mass Could Exist In Our
Universe The inertial and gravitational mass have to be the same
for conservation of energy. Consider the thought experiment
where you have two metal spheres isolated in space apart from
one another each with zero velocity. Their gravitational mass
accelerates them together for a collision (let's say perfectly
elastic), they rebound in the opposite direction and their
inertial mass keeps them going against the gravitational pull
between them until they are apart again with zero velocity by
the same distance , at which point the whole process repeats.
