Forgetting feels like a failure of attention, but physics treats it as a fundamental process with a measurable price. At the ...

Physicists are rethinking time itself. Long treated as a basic part of the universe, time may instead be an illusion—a side effect of quantum entanglement. A new study challenges the traditional idea ...

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 ...

Experimental scientists have created time crystals as a new matter form that demonstrates periodic organization only in temporal domains rather than spatial ones. The fourth-dimensional pattern of ...

Contemporary physics has learned to describe the universe with unprecedented precision. Yet when it tries to say what time is, it stumbles again and ...

The entangled clocks can test how quantum theory behaves in the presence of curved space-time as predicted by Einstein, or whether our current theories break down. Hoboken, N.J., July 14, 2025 — ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

Scientists have, for the first time, experimentally proven that angular momentum is conserved even when a single photon splits into two, pushing quantum physics to its most fundamental limits. Using ...
