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

The story begins with the black hole information paradox. According to relativity, anything that falls into a black hole is ...

What if gravity repelled instead of attracted? This video explores how repulsive gravity could have shaped the history of the ...

Planets that orbit white dwarf stars should be too hot to host alien life, theories suggest. But a new study accounting for ...

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

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

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 ...

Albert Einstein's general theory of relativity predicts so much about the universe at large, including the existence of gravitational lenses or "Einstein rings." And yet his famous equations struggle ...

In 1915, Albert Einstein published his pioneering theory of general relativity (GR) which beautifully describes the nature of gravity and its effect on large objects in space. Since then, this work ...

Aristos is a Newsweek science and health reporter with the London, U.K., bureau. He is particularly focused on archaeology and paleontology, although he has covered a wide variety of topics ranging ...

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, ...
