Physicists discover time can flow both ways in materials

For example, a video of a swinging pendulum would look the same if you played it backward. We see time as irreversible because of another law of nature, the second law of thermodynamics. This law says that the disorder in a system always increases. If the broken glass reassembled itself, the disorder would decrease.

The same law applies to the aging of materials. But physicists from Darmstadt have found out that this is not the case. They have discovered that the motion of molecules in glass or plastic can be reversed in time if you look at it from a special angle.
