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 ...

For more than half a century, faster than light travel has lived in the realm of television scripts and paperback science fiction. Now a cluster of theoretical breakthroughs is forcing physicists to ...

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 ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human ...

Physicists have directly mapped a hidden kind of geometry inside quantum materials that steers electrons in ways strikingly ...

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 ...
