Is Standing Still the Third way
If, as has been postulated, there are two streams of gravitational time, each traveling in opposite directions, would it not therefore be reasonable to suggest that where they meet, or collide, is the moment of present, the now. Which then might infer that the present is stationary, unmoving, as the two streams cancel each other out at the time-event horizon, or present moment. Might we be able to only observe, or at least sense, the past, as the results of that collision moving backwards (from our standpoint), as if we were moving forwards, but only because we are only able to look backwards and document what has just happened. Walking backwards for Xmas as it were. If we are not able to look in the other direction might that explain why we cannot observe, or accurately predict, the future. By contrast, an observer in the opposing stream of time would be looking backwards (from our standpoint), at a past that is, simultaneously, the future of his/her opposing observer.
But we can predict the future, because prediction is not the same as recording or documenting a happening. I can say that in approximately six days time a machine will be turned on that will appear to chaotically juggle 49 spheres, each with a different numeral written on them, in space-time and then randomly select only six spheres as lucky, winning, numbers in a lottery. But I cannot, however, and to my continued immense frustration, accurately predict which six numbers are going to be drawn in six days time - at that moment of 'now' when two streams of opposing time collide in such a way as to determine the outcome of that lottery. When a seemingly chaotic system reveals a static, ordered, outcome and one which can only be observed looking back upon it. But, in all probability, for a few lottery participants at least, that moment of 'now' will change their futures, or at least the probable predictability of their futures, as determined by the amount of cash they each have available.
So we get the sense of traveling 'forward' in time, but are, in fact, stationary, only able to observe moments 'past', which implies a 'forward' momentum and gives us the impression of travel. A bit like that peculiar sense one gets when sitting on a train known to be at rest, at a platform of the station, when suddenly the train on the next track starts moving and for a brief moment the laws of space-time seem to have been broken and one starts, at the very least, to worry about the implications that Waterloo station and indeed the rest of London, the UK and the entire known universe, are all heading towards the West Country in time for tea.
I need a little lie down now, but I am happy to contemplate upon the probability that my opposite, babbling, commentard of the future El Reg, coming towards me at this very moment, can say something to the effect of: “T, that I doing, the get, shirt”.
