Thank you all for your responses.
My question in the OP is linked to "expanding space". However, I was not planning to discuss whether space is expanding or not. My main concern was (is) how a physical entity like light can interact with a concept (like space).

I have pointed out that the representation of a vacuum as "empty" and free of potential "victims" for the photon is itself a false model (snip) ... Space is not empty, and while bosons may pass freely through each other, fermions will interact. (snip) ... I prefer a collision with particles involved, conservation laws upheld, and all species accounted for with numerical algorithms....that's how the LHC is set up

then we wouldn´t need "expanding space" as an explanation for the cosmological redshift
