In a groundbreaking study published in Nature Physics, researchers from the Technical University of Darmstadt in Germany have discovered evidence of time travel at a microscopic level. The study, “Time reversibility during the ageing of materials,” was co-authored by Till Bohmer and Thomas Blochowicz and focuses on the time-shuffling behavior within the structures of certain materials, such as glass. The researchers observed the glass samples using scattered laser light and 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 revelation may lead to a shift in how we perceive the materials we interact with daily. However, because the composition of these materials is constantly changing, it is impossible to determine whether the changes are occurring forwards or backwards in time. This discovery will not bring humans any closer to actually traveling through time, but it may lead to new insights into the nature of time and material properties.
Meanwhile, another new study released in 2023 proposes that time in the universe only flows in one direction, ruling out the possibility of time travel. This study explores how light interacts with other objects, ultimately determining that time can only progress in one direction. Despite these findings, scientists continue to explore new possibilities for understanding and manipulating time at various scales, from subatomic particles to entire galaxies.
