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 ...

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

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

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

Thanks to Einstein’s relativity, time flows differently on Mars than on Earth. NIST scientists have now nailed down the ...

An international team of astronomers has conducted a new test of Albert Einstein's famous theory of general relativity (GR), finding that it works even in extreme gravitational environments, according ...

Quantum mechanics has been successful beyond the wildest dreams of its founders. The lives and times of atoms, governed by quantum mechanics, play out before us on the grand stage of space and time.

Scientists are trying to figure out to what extent a new theory of quantum gravity will reproduce general relativity. Scientists at Texas A&M University in the US explore this question in a paper ...

First of all, the prevailing quantum theory, quantum field theory, is fully relativistic from the onset. Relativity is “built into” the theory, so to speak. And it’s the only quantum theory that is ...

In 1915, Albert Einstein put forth a new theory of gravity: General Relativity. Instead of every mass in the Universe instantly reaching across to every other mass and exerting an attractive force, ...
