The world’s best clocks may be sensitive to an odd mix of quantum and relativistic effects that would stretch time and test ...

Physicists have unveiled a new type of time crystal that is governed by quantum behavior that conflicts with classical models ...

Time travel has long been a staple of science fiction, captivating imaginations with the possibility of moving through time as easily as we travel through space. However, the question remains: how ...

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 — ...

Researchers have developed a method to model a central theory of quantum gravity in the laboratory. Their goal: to decipher previously unexplained phenomena in the quantum world. Gravity is no longer ...

An international team of researchers has identified a quantum counterpart to Bayes’ rule. The likelihood you assign to an event is influenced by what you already believe about the surrounding ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...

But Luis Jauregui’s work, which might power quantum computers needed for long-range space exploration, also shows how basic ...
