Gravity, the force that attracts objects toward each other, is currently framed by Albert Einstein's theory of general ...

Scientists have uncovered a surprising connection between quantum gravity and an exotic quantum state of matter that could ...

Scientists from Brown University in the USA have proposed a solution to one of the biggest problems of modern physics related ...

The cosmological constant, originally introduced by Einstein as a measure of vacuum energy density, has re-emerged as a central challenge in understanding the observed accelerated expansion of the ...

Physicists sometimes come up with crazy stories that sound like science fiction. Some turn out to be true, like how the curvature of space and time described by Einstein was eventually borne out by ...

We know that the universe is getting bigger. And we know that the speed that the universe is getting bigger is also getting bigger. The standard assumption is that the acceleration rate is itself ...

Cosmological models with varying fundamental constants explore the possibility that quantities traditionally regarded as immutable—such as the speed of light (c), Newton’s gravitational constant (G) ...

Using a new framework, astronomers arrived at the most precise measurement of our universe’s expansion rate—but things still don’t add up, they say. Reading time 3 minutes One major, unsolved problem ...
