Article Title:Spacetime without reference frames: An application to the velocity addition paradox
Abstract:
Much conceptualisation in contemporary physics is bogged down by unnecessary assumptions concerning a specific choice of coordinates which often leads to misunderstandings and paradoxes. Considering an absolute (coordinate-free) formulation of special relativistic spacetime, we show clearly that the velocity addition paradox emerged because the use of coordinates obscures that the space of relativistic observers is 'more relative' than the space of non-relativistic observers.
