Time travel has long been a fascination for humans, but it was only a concept until now. Scientists have recently discovered evidence of time travel at a microscopic level, which challenges our understanding of how time behaves. A new study published in Nature Physics, “Time reversibility during the ageing of materials,” co-authored by Till Bohmer and Thomas Blochowicz from the Technical University of Darmstadt in Germany, has focused on the time-shuffling behavior within the structures of certain materials such as glass.
The researchers used scattered laser light to observe the glass samples and discovered that they are constantly in a state of time reversal at a molecular level as they push and reform into new molecular arrangements. The ultra-sensitive video camera recorded these changes, making it impossible to determine whether the changes are occurring forwards or backwards in time. This revelation may lead to a shift in how we perceive the materials we interact with daily.
Meanwhile, another new study released in 2023 proposes that time in the universe only flows in one direction. This study explores how light interacts with other objects and ultimately determines that time can only progress in one direction. While this discovery does not bring us any closer to actually traveling through time, it does challenge our understanding of how time behaves on a cosmic scale. Overall, these studies highlight the complex nature of time and its impact on our world.
