We have always nurtured the fantasy of going back in time, either to correct past mistakes or to carry out those actions that were pending and that we wish we had done. Nevertheless, This possibility is so unattainable that we associate it with science fiction.
It should be noted that In daily life, we perceive the flow of time in only one directionbut in the field of physics, this is not so obvious, since the formulas that describe the movements apply regardless of the direction of time.
A group of researchers from the Technical University of Darmstadt in Germany, in collaboration with Roskilde University in Denmarkcarried out an experiment that reveals the reversibility of time in some materials, such as glass.
While a cup that is dropped and broken does not put itself back together. However, What would happen if there were materials that could go back in time? That’s what researchers led by Professor Till Böhmer have discovered.
Glass and reversible time
In accordance with Science Alert, the secret of this discovery lies in the temporal reversibility of some materials, such as glass. Unlike where time flows in a single direction, the equations that describe the molecular movements in these materials allow the possibility of reversing the direction of time.
The team presents the results of an experiment that sheds light on a phenomenon that has defied understanding for decades. Material time, an internal clock specific to each material, measures the passage of time in a way that escapes normal perception.
But how did these scientists manage to measure this material time, a concept that has remained hidden for more than half a century? The teacher Thomas Blochowicz and his team faced an experimental challenge never seen before.
Since glass slowly ages in ways that cannot be captured by simply looking at it closely. With a high sensitivity video camera, recorded the small molecular fluctuations that constitute the fabric of material time.
They did not simply observe the movement, but documented the details that reveal the true nature of this phenomenon.
The results were surprising: in terms of material time, the molecular fluctuations are reversible. However, it is important to understand that this does not mean that we can reverse the aging of materials in reality.
Material time, like an ideal pendulum, may swing symmetrically back and forth, but aging remains an inevitable reality.
