No matter how much we try, we can’t remember tomorrow. And physicists have no idea why.
With the hope of discovering the source of the Time River, the physicists of the University of Surrey, Thomas Guff, Chintalpati Umashankar Shastry and Andrea Rocco sought signs of their existence in the equivalent of a hot quantum bathtub under the infinite expansion of eternity.
It is not necessary to say that they did not find what they were looking for, instead, to confirm that time flows back as easily as forward in the buzz of quantum mechanics. However, the lessons learned could one day reveal why physics insists on the existence of history.
To use correct jargon, physics is generally symmetrical when it comes to time. It is possible that we never see an egg channel or an oak returns to a acorn, but when most processes are stripped of their fundamental laws, there is little dictating what end of an equation must face the past and what is the future.
It is not as if there were a shortage of places to look for clues about why the past is blocked instead. Cosmologists have observed how the universe expands from a state of entropy low to high, for example. Quantum physicists have wondered if the growing network of the tangle of a particle with the environment could be involved. Until now, nothing has stood out as a clear explanation of why the dimension of time has so much cohesion.
Guff, Shastry and Rocco wondered if quantum movement equations could still hide a means to make a return to a past state impossible, acting as a kind of ratchet that guarantees that the laws of a system do not turn back.
Used a mathematical approach known as Markov chain To describe a simplified model of heated particles that are push in an open container. Applying Markovian’s dynamics, in which the system has no memory beyond the present, each new quantum state within the system would depend on a single previous state, which could mean a trip to the tomorrow’s field or an oscillation with the same ease carries the particles back.
It doesn’t matter where the equipment looked at in the equations of their bathroom, they could not find signs that the symmetry of time investment disagree with how quantum activity was developed, which implies the “memory” of the Markovian system had no preference for A past or future.
“Our findings suggest that, although our common experience tells us that time only moves in one sense, we simply do not know that the opposite direction would have been equally possible,” says Rocco
If time can move from one side to another on a quantum level, it is certainly not on the scale of the physics we experience. It is guaranteed that a real hot bath under the stars will cool quickly as the energy flows to the cosmos in constant expansion.
The trio insists that his findings do not contradict this law of thermodynamics in any way. After all, some physics laws are truly irreversible. However, turning the time arrow on a quantum scale would still have seen a stable cooling, which suggests that there is nothing too special in one direction on the other on a quantum scale when it comes to thermodynamics.
If so, our collective experience on Time One-Way Street could be balanced on the other side of the Big Bang by a second avenue, one that is also carried by the cosmic expansion and the increase in energy from a starting point quantum that remembers the future as easily as the past does.
