An international team involving Northwestern University​ announced Tuesday that it has reached a major milestone in its quest ...

Scientists studying a mysterious effect called cosmic birefringence—a subtle twist in the polarization of the universe’s oldest light—have developed a new way to reduce uncertainty in how it’s ...

This brings us a huge leap forward in our understanding of the universe.

For decades, astronomers have believed that dark matter and dark energy make up most of the universe. However, a new study suggests they might not exist at all. Instead, what we perceive as dark ...

Cosmic voids may seem like the emptiest places in the universe, stripped of matter, radiation, and even dark matter. But they’re far from nothing. Even in these vast empty regions, the fundamental ...

Particle physics continues to probe the most fundamental constituents of matter while dark matter research seeks to illuminate the unseen mass that permeates our Universe. Recent efforts have ...

The magnum opus of particle physics is far from complete, requiring physicists to devise many alternatives—some weirder than ...

Dark matter is a real pain in the neck. The term dark matter itself refers to a hypothetical substance that seems to solely interact with the rest of the universe via gravity and to serve as the ...

For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the bending of space and time. Quantum mechanics governs the world of particles ...

It’s one of the most memorable moments of my career – and not in a good way. I was giving a talk to a room packed full of eminent astrophysicists, but there had been a bit of a childcare crisis, so ...

A recent study by Rajendra Gupta, published in "Galaxies," proposes that cosmic phenomena conventionally ascribed to dark matter and dark energy can be explained by the temporal weakening of ...
