Researchers have recently made a groundbreaking discovery of time travel at a microscopic level, which has long been a fascination for humans. Though the concept has only existed in fiction until now, a new study published in Nature Physics by Till Bohmer and Thomas Blochowicz from the Technical University of Darmstadt in Germany has shed light on this phenomenon.
The researchers focused on the time-shuffling behavior within the structures of certain materials, such as glass, and their findings suggest that time does not behave in a purely linear manner. Using scattered laser light to observe glass samples, they discovered that the glass is in a constant state of time reversal at a molecular level as it pushes and reforms into new molecular arrangements. This was recorded using an ultra-sensitive video camera.
Because the composition of these materials is constantly changing, it is impossible to determine whether the changes are occurring forwards or backwards in time. While this revelation will not bring humans any closer to actually traveling through time, it may lead to a shift in how we perceive the materials we interact with daily.
In another study released in 2023, scientists explored how light interacts with other objects and determined that time can only progress in one direction. This ruling out the possibility of time travel.
