No matter how difficult we try, we can’t remember tomorrow. And physicists have no idea why.
Hoping to discover the Source of Time’s River, University of Surrey physici Thomas Guff, Chintalpati Umashankar Shastry and Andrea Rocco looked for signs of his existence in the equivalent of a hot quantum bath under the infinite Expanse of eternity.
Unnecessary to say that they did not find what they were looking for, instead, the time confirms just as easily as he does ahead in the buzz of the quantum mechanics. Nevertheless, one day the lessons learned could reveal why physics insists on the existence of history.
To use the right jargon, physics is generally symmetrical when it comes to time. We may never see an egg disconnection or an oak back to a glans, but when most of the processes are undressed to their fundamental laws, there is little dicling which end of a comparison the past should face and what the future.

It is not as if there is a shortage of places to hunt on instructions about why the past has been locked in place. Cosmologists have looked at how the universe sets itself off from a low to high entropy state, for example. Quantum physicists have wondered whether the ever -increasing net of the entanglement of a particle could be involved with the environment. Until now, nothing has not been noticed as a clear explanation why the dimension has such a cohesion in time.
Guff, Shastry and Rocco wondered if quantum comparisons of movement can hide another way to make a return to a state of the past impossible, like a sort of ratchet that ensures that the laws of a system do not slide backwards.
They used a mathematical approach that is known as a Markov chain to describe a simplified model of heated particles in an open container. Applying Markovian dynamics, in which the system has no memory outside the present, every new quantum condition within the system would depend on just a single previous status, which could mean a one -way trip to Morgenland or an oscillation that is just as easy to take back particles .
Where the team also looked in the comparisons of their bath, they could not find signs that time-in-terms symmetry was at odds with how the quantum activity unfolded, which implied ‘memory’, which had no preference for a past or future.

“Our findings suggest that although our common experience tells us that time is only moving one way, we just don’t know that the opposite direction would have been as possible,” says Rocco.
If the time can shake back and forth at a quantum level, this is certainly not on the scale of the physics we experience. A really hot bath under the stars is guaranteed to cool quickly while the energy flows into the ever -growing cosmos.
The trio insists that their findings do not contradict this law of thermodynamics in any way. After all, some laws of nature are really irreversible. But turning the arrow of time on a quantum scale would still have seen steady cooling occur, which suggests that there is nothing too special about one direction above the other on a quantum scale when it comes to thermodynamics.
If so, our collective experience of Time’s One-Way street can simply be balanced on the other side of the Big Bang by a second Avenue, one that is also taken away by cosmic expansion and increasing energy from a Kwantum starting point that remembers the future as easily as the past.
