An honest answer, we do not directly observe/see photons in space, ok good we are in agreement of something.
For the moment can we forget about Photons being detected by the eyes and discuss the above?
Would you agree that when you don't see photons in ''empty'' space, you see ''empty space'' as an ''empty'' whole?
Please regard the question and answer on what you see around you..
That seems bizarre philosophy, not physics.
I don't see empty space, because I can't see empty space.
I may know that space is there (i.e. from distance between me and other stuff), but that's not the same as seeing it.
Put a box in that space, maybe I'll see that box.
(All of my answers have been "honest". If anyone here has been dishonest, it's you. You come in with a question, then later it's clear you really just want to push a view.)
