Sorry to state this bluntly: your concept of "radiant energy" is pure and unphysical nonsense. You seem to have in mind a kind of classical solution of the electromagnetic field equations (aka Maxwell equations).
The word "radiation" in Hawking radiation is referring to the escaping particles...
Concerning the metric: I can let you know when I have it published (which I intend to do). Otherwise, I thank all contributors again, I have indeed profited from some of the constructive comments (Yes, Ibix, this is what I mean - but not static stacking). But with all due respect I won't waste...
I strongly disagree with the statement that "only radiant energy" can produce charged particle pairs (as long as the net charge is zero (charge conservation)). In fact, any kind of primary energy can produce such pairs, as long as the conservation laws are obeyed and a part of this energy goes...
Thank you for the comments, all are helpful, but some of them are at least a few steps ahead of me.
First of all, the example with the "bulge" in an otherwise flat sheet of paper can be considered a purely geometrical problem without talking about spacetime at all. This one is already...
The proper word is not "polarity", but "charge". Any such charge, whether it is the "electric" charge or the color charge associated with quarks and gluons, is the indication for a symmetry of the universe. This principle was discovered by the famous female German physicist Emmy Noether. From...
Let us start with a simple two-dimensional space that is asymptotically flat, like e.g. sheet of paper on a desk. Geodesics in this space are straight lines in the traditional sense.
Now add a bulge in the center of this space. without affecting the asymptotic flatness. Say, we simply distort...
