Photons are massless.
Therefore I can never run out of photons.
Photons generate electrons.
Therefore I can never run out of electrons.
Store the electrons......................

I doubt photons are massless. They have ‘negligible’ mass. That is not zero mass.

Black hole gravity pulls in anything that has mass. If photons were massless they would not get sucked into black holes.
