Researchers at Hiroshima University have developed a realistic, highly sensitive method to detect the Unruh effect—a long-predicted phenomenon at the crossroads of relativity and quantum theory. Their ...

In quantum physics, a phenomenon known as the “observer effect” flips the script on our understanding of reality. This is the idea behind Pop Mech’s new story, “‘You’ in Other Universes May Be ...

Researchers have created quantum control techniques that can make a system appear to run backward in time. By precisely managing quantum measurements, they can reshape the system's arrow of time and ...
