But your colleagues have insisted that the flashes have no 'places'.

You have assumed the flashes are at rest with the ground.

Simple to a simpleton....Ken is far smarter than any dingleberry here even though he is silly enough to believe in an

Your logic doesn't exist.

Yes I have told everyone here about that.

Your stupidity confirmed...as Ken so wisely pointed out.
If the speed from both ends of the train is c in the train frame then Paul, who is at the centre, MUST receive them

End of RoS...End of Einstein!
