This is the first spacetime to be written down in which a warp-drive is not required to have exotic negative energy. That one ...

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

This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...

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 ...

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 ...

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 ...

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 ...
