  While our natural intuition suggests us that we live in 3D space evolving in
time, modern physics presents fundamentally different picture: 4D spacetime,
Einstein's block universe, in which we travel in thermodynamically emphasized
direction: arrow of time. Arguments for such nonintuitive and nonlocal living
in kind of "4D jello" come among others from: Lagrangian mechanics we use from
QFT to GR saying that history between fixed past and future situation is the
one optimizing action, special relativity saying that different velocity
observers have different own time directions, general relativity deforming
shape of the entire spacetime up to switching time and space below the black
hole event horizon, or the CPT theorem concluding fundamental symmetry between
past and future for example in the Feynman-Stueckelberg interpretation of
antiparticles as propagating back in time.
  Accepting this nonintuitive living in 4D spacetime: with present moment being
in equilibrium between past and future - minimizing tension as action of
Lagrangian, leads to crucial surprising differences from intuitive "evolving
3D" picture - allowing to conclude Bell inequalities, violated by the real
physics. Specifically, particle in spacetime becomes own trajectory: 1D
submanifold of 4D, making that statistical physics should consider ensembles
like Boltzmann distribution among entire paths (like in Ising model), what
leads to quantum behavior as we know from Feynman's Euclidean path integrals or
similar Maximal Entropy Random Walk (MERW).
