The theorized unseen structure of spacetime could also explain of the outstanding questions about the accelerating expansion ...

For more than a century, physics has treated space and time as the smooth stage on which the universe unfolds, a flexible ...

Lorentzian geometry forms the mathematical cornerstone of modern spacetime theory by providing a framework in which the causal structure and metric properties of the universe can be rigorously ...

A recent study published in Nuclear Physics B examines how hidden dimensions might influence the physical reality that we ...

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...

Physicists from the Eötvös Loránd University (ELTE) have been conducting research on the matter constituting the atomic nucleus, utilizing the world’s three most powerful particle accelerators. Their ...

A supermassive black hole was caught twisting spacetime, offering the clearest real-world evidence yet for Einstein’s frame-dragging theory.

Theoretical physicists have long debated the possible existence of wormholes, which are mathematically possible, but no evidence points to their physical existence. One theory suggests that these ...
