Why we can not see the future?

How does science work? And what's all this about quantum mechanics?

Yes.

Would you care to explain why you think this to be so?
The time direction is fully inariant under TR :(

The general solutions of the Einstein field equations may not deal with time -symmetry violations. There are even solutions to them that violate causality. However, no one claims that all possible solutions to the equations must be physical.

It seems that there is only one real reason - the future does not exist (yet):(

But what does that even mean? The future does not exist (yet). The past does not exist (any longer). But it's not like what happened yesterday didn't happen or like what will happen in the futere won't happen.

Is it not more reasonable to conclude that it's "now" that does not exist?

What do you mean?
I wonder which of physical law or expression/equation is responsible for it (for we can see only historical part of "space-time")... Why the light cannot go against the time axis?
I think the problem is how see time. We use the metaphor of a linear sequence as if it were a road, with a beginning and moving forward to a possible end.
Trouble with that is that when we use a road we have a common understanding that we can go in either direction, slow down or retrace our steps; or that we know where we are going.
This is a poor metaphor.
Why can't light go against the time axis??? There is no such thing.
There is and never was such a thing as a future. the future is a perpetual state of yet to be. Why can't you see it- because it is invisible - not the sort of thing for which this question makes any sense -literally. You might as well ask what does blue smell like.

But the past doesn't exist anymore.
Because of thermodynamics information about the past can be stored.

Information is not a natural category. It makes no sense to talk of information in this context. it seems to becoming a more common feature of "science". But it is nothing but a metaphysical concept being attached to a physical phenomenon. No good will come of it.

To it be clear enough: time-space does not exist :(

Suppose there is a bottle with separated black and white beads. Such system bears some information, some order related with physical instability no matter what context is used ... In any case there is necessary certain work to create it. I suggest dealing with such kind of work as imaginary work :)

A handful of sand contains different sizes of grain. One might want to divide up the quantity into two heaps; one contains the smallest grains, whilst the other contains the larger grains. The decision as to which size marks the boundary between small and large could be arbitrary, or you could engineer the criterion on a result which guarantees both samples have either the same number of grains OR to ensure the heaps weigh the same. Alternatively you could reject the idea of size and go for weight, and decide any other set of criteria; shape colour etc.. When you have done that you could decide that you actually want 3 heaps or 27 heaps. Then you might drop some sand or choose another handful. The earth abides our hybris passively.
Where is the information in all of this???

Surely it is nothing more that human conceit? The information does not lie in the sand, but in the human conception of it. Thus the "information" is not IN the universe but in our minds. We would always do well to remind ourselves of this simple fact.

If we or the time mixes mentioned black and white beads no physical parameter will be changed but the entropy. It perhaps provides some kind of information about the status of such system...

I'm guessing that you did not actually read what I wrote. Never mind.

I have read it carefully of course, but i know such opinion.... the question is whether any physical parameter is changed after mixing or whether such mixing could change the entropy of mentioned system?
