One could even make the case the energy is negative, as the BHs absorb more than they emit. But in any event the OP's theory is off by so many orders of magnitude it doesn't really matter. 30? 90? Does it really matter?
I assume this is entirely your own plot from released data, and that's why you use non-standard terms like "hearmap" and "satellite".
It might be physics, as @mfb said. Or it might be some artifact of noise, or geometry or both. Without knowing a lot more about what went into this plot, it is...
Apart from the fact that it is a personal theory and therefore off-limits on PF? Or that the one-way speed of light is not a defined quantity but depends on your measuring convention - as has been said over and over again on PF including this very thread? Or something else.
As a famous man once said "It depends on what your definition of 'is' is."
As far as the first part, not only is hawking radiation negligible, but its also ordinary thermal radiation - not anything dark.
I'm talking more about ships logs and not radio logs.
The big advantage of a ship's log being electronic is that you can automatically keep copies at multiple sites - especially not on the ship. If you lose the ship, you keep the log. OK, maybe its stale by an hour or a day, but you still have it.
I suspect this will go in circles until people lose interest or it is closed.
Consider only EM for the moment. What is radiation and what is near filed is dependent on the observer. I am 99% sure this cannot be uniquely defined at a single point - so you need two observers, and the pairs will...
First, those are words. The truth is in the math.
Second, those are your words. We need to flesh out what you need.
Finally, you can complain that you didn't get a nice sound bite for an answer. But knowledge is not just a collection of sound bites.
Do they still use that? I haven't seen a real logbook in the sciences in decades.
This also may not solve the problem. At Lab A, the culture is to "writ down everything, and annotate after the fact if necessary". At Lab B, it's "don't write down problems until you have a solution" - e.g...
