I mean the evidence that you originally requested.

Yes, I'm asking you where or what that is. You just keep saying "the one I mentioned originally." I'm not sure where that is, because it's not anywhere in this comment thread.

ideas i have encountered often include a “black sun” or other radiation source we can’t see in the visible spectrum.

I'm not asking about ideas that you've encountered. I'm asking what your findings have led you to believe as the most plausible reality. Has anything, to your knowledge, been verified?

My usage did not preclude other, perhaps less conventional, meanings for the word projection.

Great! Neither does mine.

So, is there any other projection that can reflect radio waves that you know existing today?

It could. It all depends on if that redirected light reaches the eye or not

I'm not looking for speculation on if it could happen. Is there any known observed instance of it actually happening at this point in time?

I'm not asking about ideas that you've encountered. I'm asking what your current speculation is. Do you not have one?
