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 ...

When speaking of our universe, it's often said that "matter tells spacetime how to curve, and curved spacetime tells matter how to move." This is the essence of Albert Einstein's famous general theory ...

From the fall of an apple to the glow of the farthest known star, gravity quietly choreographs almost everything that happens ...

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 ...

Imagine if we could use strong electromagnetic fields to manipulate the local properties of spacetime—this could have important ramifications in terms of science and engineering. Electromagnetism has ...

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 have spent a century trying to reconcile the smooth fabric of spacetime in general relativity with the jittery quantum fields that govern particles, and gravity has stubbornly resisted ...
