Dubbing these “closed timelike geodesics” (CTGs), Ralph and Sajeendran explain in the paper: “Such a CTG would be ideal for ...

Time may not be a fundamental element of the universe but rather an illusion emerging from quantum entanglement, a new study suggests. Time is a thorny problem for physicists; its inconsistent ...

In the world of quantum physics, the rules that govern reality behave in ways that challenge what we think we know. Particles can be in two places at once. Actions on one particle can instantly affect ...

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 — ...

Time travel is one of the most captivating tropes in science fiction, inspiring countless stories of adventures through the ...

John Clarke, Michel Devoret, and John Martinis awarded Nobel Prize 2025 for discoveries driving quantum computing.

Quantum mechanics is our most successful physical theory. Created to account for atomic phenomena, it has a vast range of applications extending well beyond the atomic realm, from predicting the ...

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 ...

A new definition of time suggests that what we once thought was a fundamental element of our physical reality could actually just be an illusion created by quantum entanglement. That's a very bold ...
