New theory shows time exists in quantum superpositions, ticks fast and slow

Researchers from Stevens Institute of Technology, Colorado State University, and NIST have developed a theory demonstrating that time can exist in quantum superposition, simultaneously ticking both fast and slow. Using ultra-precise atomic clocks cooled to absolute zero and manipulated with laser pulses, scientists showed that when a clock's motion is studied quantum mechanically, it can measure different rates of time passage simultaneously. This breakthrough merges Einstein's relativity with quantum mechanics, revealing that quantum fluctuations alone affect how time flows, opening new possibilities for understanding fundamental physics.
