Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study ...

The rapid acceleration of the universe’s expansion continues to challenge our understanding of fundamental physics. Why the ...

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

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 ...

A century after Albert Einstein sketched out his radical picture of gravity, astronomers have now watched a black hole ...

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 ...

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 ...

Why the universe is expanding faster and faster remains one of the biggest open questions in physics. Current theories cannot ...
