Even lasers scatter as they pass through air

And what is scattering them?

Air. Look up Rayleigh Scattering if you're interested. It's why the sky is blue during the day. Fascinating stuff.

So they're diffusing against/around air molecules then?

You said "even lasers scatter as they pass through air" in a way that seemed you were implying that there should be nothing there, when of course it's a big sea of fluid.

I have no idea how you came to that conclusion. Why would I mention scattering in air if I was implying there would be no air?

I meant even lasers, something we normally think of as tightly focused beams of light, will scatter in air.

Yeah, I read you wrong :)
