How much faster you'd 'age' on Mars – relatively speaking

"Nobody knew that before. It improves our knowledge of the theory itself, the theory of how clocks tick and relativity. The passage of time is fundamental to the theory of relativity: how you realize ...

Ultracold clocks could reveal how quantum physics alters time

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 ...
