Einstein’s Theory of General Relativity is currently our best approximation of how the universe ticks. But there are holes.

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

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

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

Scientists have determined a way to measure gravity on microscopic levels, perhaps bringing them closer to forming a theory of "quantum gravity" and to solving some major cosmic mysteries. Quantum ...

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 ...

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

"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 ...

Newton's theory of gravity posited instantaneous gravitational attraction, successfully predicting planetary orbits. Einstein's special relativity challenged this, necessitating the development of ...

Unifying quantum mechanics with general relativity is the ultimate dream — or nightmare — of physics. It would be a way to finally describe the force of gravity with the tools of quantum mechanics, ...
