For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.

Gravity is supposed to be the most familiar force in nature, yet at the deepest level it remains the least understood. A bold ...

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 ...

The rapid acceleration of the universe’s expansion continues to challenge our understanding of fundamental physics. Why the universe is expanding faster and faster remains one of the most intriguing ...

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 ...

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

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 ...
