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 ...

Quantum gravity and cosmology represent a frontier in theoretical physics where the principles of quantum mechanics are integrated with the framework of general relativity. This synthesis is crucial ...

Over the past 50 years, astronomers have made dozens of major discoveries that help explain the nature and origins of the universe. They’ve measured the cosmic microwave background, or leftover ...

It feels so obvious that time moves forward that questioning it can seem almost pointless.

Renowned physicists, including two Nobel Prize winners, will gather at the Vatican Observatory near Rome next week to ponder the unresolved mysteries of the cosmos and to honor the legacy of Georges ...

Dark matter remains one of the most compelling enigmas in modern cosmology. Although it does not emit light, its gravitational influence is essential for the formation and evolution of cosmic ...

Sci-fi loves a multiverse. Everyone from Rick and Morty to Spider-Man has stepped through a portal and met their alter egos. My personal favorite use of this trope comes from the sitcom Community, ...

At CERN’s Large Hadron Collider on the edge of Geneva, scientists have reported a surprising twist in the behavior of matter.

It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is described extremely well by quantum theory, while the world of gravitation ...

Gayoung is a science writer for Gizmodo primarily covering physics, cosmology, and quantum science, with the occasional story on weird critters. Before joining Gizmodo, Gayoung wrote about a wide ...
