Of course you can.

You model, in order to make predictions is mathematical (geometric) .. not
that it DOES make any predictions.

Sigh.

Since light does not behave like bowling pins, floating
or otherwise...

Cannot possibly be mathematics at all. Everything is explicitly
designed so that absolute existence and absolute nonexistence are not
possible in this scheme. I disagree that this is math. Nothing is
proveable in this scheme, all is conjectural. Conjectures can be
consistent, but if proof is impossible you are certainly not doing
mathematics.
