Mind = blown.

Physicists are quietly testing wild new theories that treat a hidden fifth dimension as more than science fiction, suggesting ...

To progress to the next level in understanding reality, we need to combine quantum mechanics and Einstein’s general ...

The ability to study graviton-like particles in the lab could help fill critical gaps between quantum mechanics and Einstein’s theories of relativity, solving a major dilemma in physics and expanding ...

The original version of this story appeared in Quanta Magazine. When it comes to understanding the fabric of the universe, most of what scientists think exists is consigned to a dark, murky domain.

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

"By understanding quantum gravity, we could solve some of the mysteries of our universe — like how it began, what happens inside black holes, or uniting all forces into one big theory." When you ...

Quantum physics is often described as the most successful scientific framework in history. In its 100 years of existence, it has explained everything from the periodic table of the elements to how ...

(PhysOrg.com) -- Since the early days of quantum mechanics, scientists have been trying to understand the many strange implications of the theory: superpositions, wave-particle duality, and the ...

The force we experience most intimately remains the most mysterious. Physicists understand how vast migrations of particles called photons light up our homes, and how swarms of “gluon” particles hold ...

Scientists aim to build the first graviton detector to explore gravity's quantum nature, despite significant challenges.

(PhysOrg.com) -- Because of the absence of gravity, fuels burning in space behave very differently than they do on Earth. In this image, a 3-millimeter diameter droplet of heptane fuel burns in ...
