Scientists have long pondered the possibility of time travel, but it has always been considered a distant dream – until now. A new study by Till Bohmer and Thomas Blochowicz, published in Nature Physics, has uncovered evidence of time travel at a microscopic level.
The research was conducted by scientists at the Technical University of Darmstadt in Germany, who examined how materials like glass age over time. The study revealed that time does not behave in a strictly linear manner as previously thought. Instead, researchers observed that glass molecules move around internally, effectively reversing time on a molecular level.
To test this theory, the researchers used scattered laser light to observe the glass structures. They witnessed the samples pushing and reforming into new arrangements due to the minuscule fluctuations in the molecules. However, due to the way glass moves around internally, scientists cannot definitively determine if these changes are occurring forwards or backwards.
While this knowledge may not bring humans any closer to being able to travel through time, it will certainly change how we think about certain materials used daily. This study comes after another from 2023 that challenges our understanding of the feasibility of time travel altogether. The research suggests that time in the universe is unidirectional and cannot be traveled back or forth due to its relationship with light and other objects.
