IntroductionIn this series, we are testing the idea that "the universe might be a simulation running on a giant computer" by ...

The reconciliation of general relativity and quantum mechanics is one of the biggest challenges in science, one that continues to elude us. Now, a new study by Anjun Chu and colleagues has examined ...

Long and winding road: The Juice space probe taking the long way to Jupiter and its moons – Copyright NASA/AFP/File NASA Scientists have unveiled a new theory that ...

Wormhole time travel is mathematically valid under general relativity, but exotic matter, stability, and quantum gravity gaps ...

Diagrammatic representation of the entropic quantum gravity action. The action for gravity is given by the quantum relative entropy between the metric of the manifold and the metric induced by the ...

Physics has a problem—their key models of quantum theory and the theory of relativity do not fit together. Now, Dr. Wolfgang Wieland from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) is ...

For the first time, physicists have measured the tiny quantum shift an object acquires by falling through Earth's gravity — an effect of Einstein's relativity that was predicted almost a century ago ...

The Earth’s gravity, manifested as curvature in space and time, is expected to alter the rules of standard quantum theory. An experiment consisting of three quantum computers at different elevations ...

Quantum Darwinism answered the question, "Why can multiple observers agree on the same result?" However, a more fundamental ...

The odds of the bet Jonathan Oppenheim made in 2023 are generous, even at 5000 to 1. But if he wins, it could transform our view of the universe. The physicist is wagering that space-time, and ...
