The universe’s accelerating expansion has long puzzled physicists. For decades, dark energy, an unseen force thought to make ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

In this last part of our series on recently digitized books from the Wenner Collection, we are focusing on works that ...

A new recipe for gravity could help solve some of the universe's greatest mysteries. It suggests that the concept of "quantum gravity" could arise from entropy, possibly solving puzzles put forth by ...

So far, the most accurate model describing gravity is still Einstein’s theory of general relativity. It states that gravity as we feel and observe it is a kind of side effect of the fabric of ...

Quantum Gravity and General Relativity represent two foundational yet traditionally disparate pillars of modern physics. General Relativity, Einstein’s seminal theory, elegantly encapsulates ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in physics." When you purchase through links on our site, we may earn an affiliate ...

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

There’s an adage coined by [Ian Betteridge] that any headline ending in a question mark can be answered by the word “No”.
