# Photon pressure

Here's a (possibly very simple) question I have:

How many photons can you fit into an arbitrary volume?

Is it infinite because they are massless/volumeless particles?

If that is the case can you fit an infinite amount of energy in an arbitrary space? (theoretically)

Thanks

Photons are Bosons, so you could fit any number into an arbitrary volume.
Infinity is not a number. It just means that there is no upper limit.
