The study by Till Bohmer and Thomas Blochowicz, published in Nature Physics, has brought new evidence to the age-old notion of time travel. Researchers at the Technical University of Darmstadt in Germany have discovered that materials like glass do not behave in a strictly linear manner when it comes to time. This means that time effectively ‘shuffles’ in the structure of these materials.
The study examined how the composition of materials changes over time and found 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, with minuscule fluctuations in the molecules documented using an ultra-sensitive video camera.
Although this knowledge may not bring humans any closer to being able to travel in time, it will certainly alter our understanding of certain materials used daily. However, a new study from 2023 challenges our understanding of the feasibility of time travel altogether. The research suggests that time in the universe is unidirectional due to a new study into light and its relationship with other objects.
