  1. Thank you verymuch guys. Food for thought.
  2. Does time pass in SR? Rietdjik(1967)-Putnam(1968)-Sider (2001) Petkov (2006) ..Russell, Penrose and others, claim that SR proves "Eternalism". That is; The world is an eternal (a-temporal) 4-dimensional spacetime manifold in which all events exist and the notion of passage of time, in other words a moving Now (a global hyper-surface of simultaneous "now events") moving towards the future is a psychological illusion. To quote Geroch; There is no dynamics within space-time itself: nothing ever moves therein; nothing happens; nothing changes[...] one does not think of particles as ‘moving through’ space-time, or as ‘following along’ their world-lines. Rather, particles are just ‘in’ space-time, once and for all, and the world-line represents, all at once, the complete life history of the particle Geroch (1978 p. 20-21) Is that physically substantial or only philosophically?
