The possibility of time travel has long intrigued humans, but it has always been seen as a fictional concept. However, recent research conducted by scientists at the Technical University of Darmstadt in Germany has provided evidence of time travel at a microscopic level.
The study, Time reversibility during the aging of materials, published in Nature Physics, explores how time behaves in the structure of materials like glass. Researchers discovered that time does not behave strictly linearly and that glass molecules consistently move to different locations, effectively reversing time on a molecular level. To test this concept, scattered laser light was used to observe the glass structures. The researchers witnessed the glass samples pushing and reforming into new arrangements. The minuscule fluctuations in the molecules had to be documented using an ultra-sensitive video camera.
While this knowledge may not bring us any closer to being able to travel through time on a human level, it will certainly change our understanding of certain materials used daily. Glass is just one example of materials with intriguing structures that do not adhere to traditional molecular structures.
In 2023, another study challenged our understanding of the feasibility of time travel altogether. The research dismisses the idea that we could ever travel back in time due to its unidirectional nature in the universe. This new study into light and its relationship with other objects suggests that time moves only forward and cannot be traveled backwards or forwards in any meaningful way.
