Time already behaves strangely in modern physics. It can stretch, slow, and split depending on speed and gravity.

Atomic clocks are already precise enough to measure tiny effects of relativity, such as time dilation; for example, if you ...

A new study suggests that time itself could exist in a quantum superposition, ticking faster and slower simultaneously, and that this effect may soon be tested in the lab. Led by Igor Pikovski at ...

What does the passage of time look like for a truly quantum object? The world’s best clocks may soon be able to answer this question, testing how time can stretch and shift in the quantum realm and ...

Physicists are preparing to test whether atomic clocks can experience quantum superposition, ticking faster and slower simultaneously. The concept merges principles from quantum mechanics and ...
