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

Some habitable worlds orbiting dead stars could be kept alive for aeons thanks to a quirk of Einstein’s theory of gravity ...

Two black holes in deep space. (The SXS [Simulating eXtreme Spacetimes] Project via LIGO/Caltech) (CN) — A merger of two black holes “ring” in the cosmos, producing ripples in the spacetime continuum, ...

He shared the Nobel Prize in Physics for his work on gravitational waves, which helped confirm Einstein’s general theory of relativity and how the universe began. By Dylan Loeb McClain Rainer Weiss, ...

The original version of this story appeared in Quanta Magazine. Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time ...

Trump budget proposal seeks to close one of two U.S. LIGO observatories by 2026. LIGO facilities detected first gravitational waves and advanced multi-messenger astronomy. Proposed closure risks ...

On May 29, 1919, a total solar eclipse helped to prove Albert Einstein's theory of general relativity. Einstein's theory suggested that gravity could bend light by curving the fabric of spacetime. To ...

Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time and the latter a point in space, but in both cases the normally ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...

In a new study published in Physical Review D, Professor Ginestra Bianconi, Professor of Applied Mathematics at Queen Mary University of London, proposes a new framework that could revolutionize our ...

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 ...

It might not be obvious to those of us only grappling with more mundane concerns, but for cosmologists bent on unlocking the universe’s deepest secrets, there’s no shortage of problems keeping them up ...
