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

Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at ...

Mind = blown.

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

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study suggests this mysterious ingredient may not be necessary after all. Using an ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

Recent advances in theoretical physics have increasingly highlighted the pivotal role of algebraic structures in unifying particle physics with quantum gravity. These approaches leverage sophisticated ...

A long-standing challenge in physics has been to integrate gravity into the Standard Model, which successfully describes the electromagnetic, weak, and strong forces. The difficulty lies in the ...

It was already a mind-bending shift, last century, to go from Isaac Newton’s absolute space and universal time to Albert Einstein’s four-dimensional space-time, which is dynamic, flexible, sensitive ...

Do dead stars glow? A strange gravitational phenomenon could be generating enormous amounts of light around neutron stars, new research suggests. When you purchase through links on our site, we may ...

Detecting a graviton — the hypothetical particle thought to carry the force of gravity — is the ultimate physics experiment. Conventional wisdom, however, says it can’t be done. According to one ...

"The singularity is the most mysterious and problematic part of a black hole. It's where our concepts of space and time literally no longer make sense." When you purchase through links on our site, we ...
