Because all the energy that built the past universe was consumed in constructing the present, and the future is no more than a set of alternate building plans awaiting selection (wave function collapse if you prefer) and availability of materials for construction. Just an interpretation. Consider observing a supernova inside some huge stellar nursery from not too close but close enough to study in reasonable detail. After the early fireworks have subsided we may expect to see a growing bright edged circle as the surrounding dust is progressively illuminated. Is it unreasonable to perceive the arrival of intense radiation at that bright edge as being experienced simultaneously around the entire perimeter even when it's several light years in diameter? And what exactly is going on at that edge other than a colossal number of particle interactions being randomly chosen from an even more colossal number of possible interactions. It may even be viewed as a phase change, but in addition to a change in physical properties it's a condensation from causes to effects. Or a condensation of an unobservable, abstract 'many worlds' future into a single throughly deterministic past with the present being a thin slice of quantum fuzz between the two. Again, just a personal visualisation to help get my head around it. Perhaps, the ambiguity of 'now' for different observers is simply an SR induced form of observer bias. Not one of them is able to observe a causal reversal, and to me, that seems to be the critical issue. Is this a reasonable view?
