The extraordinary experiment opens the door to a new generation of devices and reveals a deeper relationship between time, entropy, and entanglement.
challenges in physics is to understand the nature of time. At the microscopic level, the laws of physics are symmetric with respect to time—they work just as well whether time runs forwards or backwards. But at the macroscopic level, processes all have a preferred direction. The great physicist Arthur Eddington called this the “arrow of time.”
Just why this arrow points in one direction but not the other is one of the great scientific puzzles. The standard answer is that the arrow of time follows from the Second Law of Thermodynamics—that disorder, or entropy, always increases in a closed system.

Explanation:
This phenomenon seems to reverse the “arrow of time,” the idea that natural processes run forward but not in reverse (SN: 7/25/15, p. 15). The existence of an arrow follows from the second law of thermodynamics. The law states that entropy, or disorder, tends to increase over time.
