"It highlights gravity's possible hidden complexity and invites a reevaluation of where dark matter effects originate." ...

For nearly a century, astronomers have watched galaxies spin and the universe expand in ways that visible matter alone cannot ...

For decades, astronomers have treated dark matter as the invisible scaffolding of the cosmos, a mysterious substance that ...

The mystery of dark matter—unseen, pervasive, and essential in standard cosmology—has loomed over physics for decades. In new ...

Neutrino particles have extremely small masses, yet there are so many of them that they carve out the large-scale structure ...

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 ...

Sensors buried deep in the Antarctic ice may help physicists figure out how gravity works in the quantum realm, the smallest scale of existence. A team of physicists says they’ve figured out how to ...

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 ...

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged. This theory tries to ...

A new argument explores how the growth of disorder could cause massive objects to move toward one another. Physicists are both interested and skeptical. Isaac Newton was never entirely happy with his ...
