Recent advancements in observational techniques have led to the capture of high-resolution images of black hole shadows, which are challenging the completeness of Einstein’s general theory of ...

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 ...

Diagrammatic representation of the entropic quantum gravity action. The action for gravity is given by the quantum relative entropy between the metric of the manifold and the metric induced by the ...

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

The study of higher dimensional gravity theories represents a vibrant and innovative field in modern theoretical physics. At its core, this research seeks to extend the familiar four-dimensional ...

The second image of the supermassive black hole in M87 was taken by the Event Horizon Telescope shows it still has a shadow just as Einstein predicted. When you purchase through links on our site, we ...

One of the weirdest theories in cosmology is the holographic principle, the idea that our universe is a three-dimensional image projected off a two-dimensional surface — the idea that, yes, we are ...

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 ...

The accelerating expansion of the universe could be explained by modifying general relativity so that gravity has mass – or so thinks a small group of physicists. Matthew Francis reports What lies ...

In a new study published in Physical Review D, Professor Ginestra Bianconi, Professor of Applied Mathematics at Queen Mary ...
