Of the four fundamental forces of physics, gravity is the one we’re most familiar with in everyday life, but it’s also the only one that can’t currently be explained by quantum physics. Now scientists ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. An abstract illustration of quantum particles entangling. New research aims to unite gravity with ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...

What if gravity isn’t weirdly quantum at all, but rather … just a bit messy? The holy grail of theoretical physics is to find the long-sought theory of quantum gravity. But what if this theory is as ...

The original version of this story appeared in Quanta Magazine. At the beginning of time and the center of every black hole lies a point of infinite density called a singularity. To explore these ...

Gear-obsessed editors choose every product we review. We may earn commission if you buy from a link. Why Trust Us? Scientists have proposed a new test to hopefully help shed some light on quantum ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth space-time with the jittery world of quantum mechanics. A new wave of ...

The evolution of quantum mechanics has continuously deepened our understanding of the microcosm, guiding researchers from the seminal formulation of the Schrödinger equation to more refined ...

Repulsive gravity at the quantum scale would have flattened out inhomogeneities in the early universe First light The cosmic microwave background, as imaged by the European Space Agency’s Planck ...
