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 ...

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

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

To progress to the next level in understanding reality, we need to combine quantum mechanics and Einstein’s general ...

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

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 ...

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

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth space-time with the jittery world of quantum mechanics. A new wave of ...
