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 ...

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

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

A new recipe for gravity could help solve some of the universe's greatest mysteries. It suggests that the concept of "quantum ...

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

Energy-momentum distribution remains a fundamental yet challenging aspect of theoretical physics. In general relativity, the localisation of gravitational energy is obscured by the equivalence ...

A bizarre "cosmic glitch" in the theory of how the gravity of the universe works may have been mended. The strange glitch in Einstein's description of gravity in his theory of general relativity may ...

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 ...
