Aren't photons subatomic particles with mass? Why can't they be contained?

Light has no rest mass and travels only at the sped of light, so we usually don't call it matter. You can contain it between mirrors, but sooner or later it will get absorbed and cease to exist.

Oh but it can...go into a room with no windows and no doors and no other escape paths (like a cave 3 miles underground)...there is no light there - it has been kept out. The converse is also true, turn the light on in that room, and you cannot see it from the surface. Light travels in waves...eventually the waves are absorbed...

We dont really understand how it gets absorded in a container(atoms)but we do know that it comes out of a contraiment.

put a box over a lightbulb?
unless you mean stored...
in which case, too fast, too small, so we change it into energy first, hence solar cells and batteries.

it's not, and it's transmitted
