The higher the pressure we can achieve inside the craft, the less field energy we'll need to counteract the rest.

The structural field energy needed to resist that would've been enormous-and for what?

This magnetic field energy resonates around the communication system, but does not radiate into free space.

We have set the zero field energy to zero for convenience.

Outside the core, the monopole has only magnetic field energy.

That liberates some field energy into heat and can even blow open a magnetic structure.

Conservation of energy requires that this gravitational field energy is always negative.

Near field energy itself is non-radiative but some radiative losses do occur.

It isn't exactly getting something from nothing, since each little genesis costs the singularity some field energy.

In the exchange, field energy was re-converted to mass.
