Re: Reg needs a new office supplier

It's not being pushed along my mass anyway, says this annoying nerf physics pendant. Which makes the paperclip analogy even more wrong. It's being pushed by momentum transfer. Photons have zero mass, but they do have momentum.

(The y have zero _rest_ mass, to be properly pedantic. Although I'm sure I'll be pedantically obliterated somehow anyway.)
