This is a weird one, but it boils down to people saying you can’t travel faster than light. But speed is only relative to another object isn’t it? I mean, I’m sat on the sofa now doing 0mph, but compared to the sun, we’re travelling thousands of mph.
So if speed is only relative to another object, does that mean two objects travelling close to SoL are actually going faster than light relative to each other?
Edit: there’s been some incredible responses which – to my endless surprise – have made perfect sense somehow! Thanks for the response!
