Stochastics mechanics and early Universe

[Dmitry67]

For a long time I was thinking that even SM has lack of deep philosophic insight, it is self-consistent and, within its own framework, can answer all questions, making all paradoxes non-issues. As a reminder, in SM macroscopic events are atomic, while all other stuff (fields, real particles, virtual particles) are ”just math” to calculate the correlation between the macroscopic events.

But what’s about the very early universe? When the very first macroscopic event did occur? Not sooner than the very first system with some sort of ‘memory’ was created. But to allow the existence of such systems, Universe must cool down enough so some systems will be away from the thermal equilibrium.

So the first seconds, minutes, and may be even years of our Universe is beyond the scope of SM.

Can you clarify what you mean by stochastic mechanics?

Strangely enough, there is almost no informtion in Wiki.
So I provide my understanding:

1. Macroscopic events and measurements are basic, like the axioms. You can't decompose the macroscopic event into microscopic subevents. The whole world is just a network of macroscopic events/measurements/observations.
2. nature is random.
3. QM provides a way to calculate the correlations (probabilities) of the events. It is just a math.

In SM wavefunction, virtual particles, real particles are not real. They are just math which explain macroscopic phenomena (like 'particle' tracks in the camera).

For example, EPR nonlocality in SM view is simple: QM gives a formula for a correlation of the outcomes observed by Alice and Bob. That's it, and that's enough. All speculation about 'wavefunction', 'hidden properties', locality and nonlocality does not make any sense in SM framework: as soon as formulas are in agreement with the experimental results, scientist is satisfied. So effectively it is a more detailed description of "Shut up and calculate".
