Can someone easily explain to me what’s wrong with this thought experiment:
I’m in a spaceship traveling at 0.500001 c . I’ve a long fishing line with knots tied every 186k miles along it’s length (told you it was long). Another spaceship traveling at 0.500001 c in the opposite direction passes me, and at that moment I hook the line onto the other ship’s bumper (fender). The line now leaves the reel and as it passes through my fingers (I’m wearing gloves) I time that the knots are passing through my hand at more than 1 per second. Isn’t the line now moving at >c? If it’s not moving at c+ why not. Not bothering with those strange photon things that physicists come up with willy woolly explanations about, I’m using good old fashioned fishing line, something with (excuse the pun) real physical properties, real length etc.
Ha got you there Einstein – get out of that one.
Confused (or possibly just simple) of St Albans
