Soon after, however, the source of the gravimetric field and power losses is found to be the crystal.

If so much raw energy were released into anything on which a force-field was focused, it would destroy the source of the field.

It cannot act on the source of the inductively created electric field, because there is none.

If I didn't know better, I'd say we were the source of the field.

Both parts have the same acceleration and the force exerted on each is supplied by the external source of the field.

The theory was only expected to hold when the source of the gravitational field is stationary.

These transformation equations only apply if the source of the field is at rest in the unprimed frame.

They then decided to find and destroy the source of the damping field, creating a bomb to do so.

"And there's no sign of a source of the field?"

This contrasts with the sources of the gravitational field, which are masses.
