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

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 ...

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 ...

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

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

The fundamental constants of nature seem perfectly tuned to allow life to exist. If they were even a little bit different, we simply wouldn't be here. Given this grave existential fact, we are forced ...

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 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.

Astronomy is, in essence, an exercise in inference. We cannot touch the stars, nor scoop up galaxies in a lab. Instead, we decipher the universe through its light — its color, intensity, rhythm and ...

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 ...
