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 ...

Wormholes have long served as science fiction’s favorite shortcut through the cosmos, but a growing body of theoretical physics research suggests they will never function as tunnels. That does not ...

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 ...

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 ...

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 ...

UNIVERSITY PARK, Pa. -- A Penn State scientist studying crystal structures has developed a new mathematical formula that may solve a decades-old problem in understanding spacetime, the fabric of the ...

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 ...

For the last 25 years, most scientists have believed that about 70% of the universe is formed by something called ‘’dark energy.’’ This invisible energy was ...
