Take the time-energy uncertainty relation, $\Delta$$E$$\Delta$$T$$\ge$$\hbar/2$.
My question is based on my confusion about the effect this relation may have within the interior of a highly compressed object such as a neutron star:
- provide a source of repulsive energy, albeit over a very short time span?
- or would it actually represent effective mass, increasing the inward directed gravitational force?
- or would it average out as in the flatspace metric, producing no overall effect?
My background is at beginner GR level, but I do appreciate that this relation can have a large effect at very short scales, I'm just not sure if these are relevant, even within a highly compressed object such as a neutron star, although a black hole is a different matter.
EDIT: I have posted an answer myself below.
