I thought photons didn't have any mass?

  No. But they do have energy, and that creates gravity in general relativity (if I understand it correctly). But also, you could have a Zeno's Paradox of particles - one with half the energy, one with 1/4th the energy, one with 1/8th...

  To be clear, I personally did think that electrons had a non-zero mass, so my bad.

  Do they even exist?
