In quantum physics, time can flow backwards. Why don't we remember tomorrow?

Salvador Dalí, “The Persistence of Memory”

What if there was an “alternative street” for the course of time? In the physical dimension in which we live, it is impossible to remember what we have not lived yet, but is this formulation so unreasonable?

Physicists Thomas GUFF, Chuntalpati UmShankar Shastry and Andrea Rocco, from the University of Surrey, sought signs of the existence of the “river of time” in the equivalent of a hot quantum tub under the infinite extension of eternity. Thus defines the quantum search for the origin of time.

The conclusions were few: Time flows right back as ease as it flows forward in quantum mechanics.

Regardless of where the team sought in the equations of the “Quantum Bath”, the, published in January in Naturedid not find signs that the time inversion symmetry was in disagreement with how quantum activity unfolded, which implies that the “Memory” of the Markovian system (Mathematical approach where the system has no memory beyond the present) had no preference for a past or future.

“Our results suggest that although our common experience tells us that time only moves in a sense, we are not aware that the opposite direction would have been equally possible“, Says Rocco.

In other words, the physics we experience has no idea of ​​this quantum idea that time can flow to the contrary – we don’t remember tomorrow, as much as we try.

If we reversed the arrow of time on a quantum scale, we would have watched a constant cooling, suggesting that there is nothing special in one direction in relation to the other on the quantum scale with regard to thermodynamics.

If so, our Collective Experience of the “Single -Sense Street” of Time can be balanced, across the Big Bang, by a “second street”also carried by cosmic expansion and the increased energy of a quantum starting point-and this one remembers the future as easily as the past.
