: : Time has puzzled people for a long time. We are so used to being within : spacetime that when we imagine ourselves outside it, watching peoples : wormlines as if they were carved in a block of glass, we feel the : need to imagine a "hypertime" to keep track of the rate at which the : "now" slides along these worldlines like a glowing spot. This is NOT : the right way to think of it. Instead, ponder that block of glass : and the worldlines of all the people in it, the worldlines of the : photons going from the Sun to their eyes (let's leave QM out for now!!), : the worldlines of the electrons moving in their brains, etc., until : you see how "from within" that spacetime could seem just like our world. : : It's only when you spend hours doing this that you really understand : the concept of spacetime at a gut level. At least that was the case : for me. The usually CAUTIOUS JB has OPENED a can of WORMS here. Is he professing a belief in strict DETERMINISM? Is he claiming that our apparent perception of the passage of time is naught but a delusion? .
