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 ...

Physicists from Stevens Institute of Technology and Yale University have launched an experimental program to detect gravitons ...

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy. When you purchase through links on our ...

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 ...

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

Albert Einstein's theory of general relativity—which explains gravity as the product of the distortion of space and time—may not be universally applicable. This is the conclusion of physicists from ...

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a ...

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged. This theory tries to ...

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

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