Photons have no mass

choose one and only one

I honestly think we should build these, because aliens would laugh so fucking hard at us moving by shooting lasers into mirrored material. They'd be like no, we should step in and help.

What is radiation pressure for $200?

Just because light carries no mass doesn't mean it doesn't carry momentum.

oh boy, oh boy

photons have no REST mass. but as they are never at rest ...

You know funnily enough, I was just thinking about this exact thing yesterday. Since I'm a brainlet I just assumed I was misinformed about what exactly a photon is. Can someone explain this?

DING DING

they do have mass, they wouldn't be moving if they didn't and that's not how solar sails work.
