Yes. In reality, Everything is here. Everything is happening Now, and it's all here. "Here and there" are subjective. Your "here and there" is not the same as mine, which is not the same as Greta's, and so on. All beings existing in the Universe have their own "here and there". The most objective view is the view of the Universe (and if you don't consider it sentient, you can just imagine if it was). From the Universe's POV, Everything is here, because Everything is Itself. There is nothing outside of Itself, so for It, Everything is in the same place. Right Here. And from Its POV (if it had one), Everything would be happening Now. To try and see the Universe from the most objective POV possible, one must imagine the Universe as the Universe would see Itself.
The reason why time seems to flow in a particular direction, and not the other, is simply because of a certain "flow" in us, not because of any inherent property of Time itself. And just as Time would flow in the opposite direction for the microbe if it could start moving in the opposite direction, so too would time seem to flow in the opposite direction for us, if we could change our psychic apparatus, i.e. if a certain "flow", which is internal to us, changed directions...
Do you have any thoughts as to how the time-asymmetrical laws of thermodynamics affect this analysis? You've pointed out a certain similarity between the acts of remembering the past and anticipating the future. You've suggested that the reason we feel that there is a difference between the two is purely a function of ourselves
. But isn't it also a function of the second law of thermodynamics? Would you say that law is subjective to a greater extent than other physical laws?
Allow me to correct myself. Our perception/cognition or time is due to the nature of both ourselves and the world. But the most important dynamic is within ourselves. We won't unravel the mystery of Time by tinkering with things outside of ourselves, but rather with changing things within ourselves (our own perception/cognition of Time). But you are quite right in suggesting that both internal and external forces ultimately are responsible for our subjective experience of Time. The point is that our cognition of Time becomes more objective when we learn to cognize it as a higher dimension(s) of space, which is something we've been "unconsciously" doing for ages by constructing timelines and calendars. When we learn to cognize Time as merely an extension of space outside the the known 3 coordinates of space, we learn to cognize Time closer to the way it really is.
As far as the 2nd law of thermodynamics is concerned, I'm not knowledgeable enough to comment on it. But as I said above, yes, you can certainly also say that our cognition of Time is a function of how the world works. Perhaps you could elaborate on exactly how the 2nd law of thermodynamics is responsible for our cognition of a 'before, now, and after'? It sort of sounds like you're proposing that we cognize Time because things change, but that is circular logic. Change and Time go hand in hand. Naturally, if we have a cognition of 'before, now, and after' we will also have a corresponding cognition of the idea of change, and vice versa. I don't think you can explain the one by the other.
But I must note that I would not take change as an absolute fact. It's no more fantastic to suggest that, in reality, while Everything seems to be in a state of flux/change, in reality nothing is really changing, anymore than it is to say that really Everything is happening Now. Perhaps things only appear to change, but in reality they ultimately stay the same, or perhaps another way of looking at it is to say that, while things are constantly changing, at the same time they don't change. For example, we could alter 'x' by adding, subtracting, multiplying, dividing, and squaring it by various values, but the final value of 'x' could still be the same if the net value of all of our augmentations are '0' (x+2-2 = x). Perhaps the Universe is like that as well. Constantly in a state of flux
, but in the end, it always remains the same....
