Science does postulate things such as the speed of light and the
'weight' of a photon. However scientists are always working on
proving/disproving hypotheses and postulates to refine them. This
can't be said for all studies.

Give me one statement in science that you cannot prove.

The speed of light is constant over time.

or how about:

The speed of light is the same now as it was billions of years ago.
