Scientists worldwide respond to the publication of the three-volume monograph “Quantum Model of the Universe” #Physics ...

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 ...

Gravity is by far the weakest of nature’s four fundamental forces, and physicists have spent decades asking a deceptively simple question: why? One answer, first sketched a century ago and refined ...

A new three-volume study explores how quantum physics, gravitation and cosmology may be understood within a unified ...

Dimensions beyond the four we’re familiar with could solve a host of problems in physics and cosmology. Columnist Leah Crane ...

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

We have long taken it for granted that gravity is one of the basic forces of nature—one of the invisible threads that keeps the universe stitched together. But suppose that this is not true. Suppose ...

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole new model to account for gravity’s influence.

Theoretical physicist Sabrina Gonzalez Pasterski, who built and flew her own airplane before she had a driver's license, is ...

Researchers created a technique to reduce uncertainty in cosmic birefringence measurements, resolving a key phase ambiguity and improving future studies of fundamental physics.

Astrophysicists have presumed for nearly a century that the universe will just keep expanding for all eternity, driven by an invisible force called dark energy. But new data suggest that this is ...
