"Glass Reveals Surprising Evidence of Time Reversibility"
Physicists have discovered the first physical evidence of time reversibility in materials like glass, uncovering a measure of time known as material time. Using a sensitive video camera to record scattered laser light and statistical interpretation, researchers found that on a molecular level, time in glass varies as particles push and pull one another into new arrangements, making it impossible to tell whether the process is being played forward or in reverse. While this doesn't mean that the aging of materials can be reversed, it provides insight into the reversible nature of time on a small scale within non-crystalline substances.
