When you look up at the night sky, it appears unchanging. But if you look deep enough you will find that the sky is in fact ...

Astronomers have long known the universe is expanding—but exactly how fast remains one of the biggest mysteries in cosmology. Different techniques for measuring the Hubble constant stubbornly disagree ...

"The polarized light of the cosmic microwave background is sensitive to new physics that violates parity symmetry," the team ...

Quasicrystals are orderly structures that never repeat. Scientists just showed they can exist in space and time.

This breathtaking clue about the architecture of consciousness supports a Nobel-Prize winner’s theory about how quantum physics works in your brain.

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 ...

In 2022 three scientists won the Nobel Prize in Physics for proving something astonishing: the universe is not locally real. In other words, particles don’t have fixed properties until they are ...

Physicists have been puzzling over conflicting observational results pertaining to the accelerating expansion rate of our Universe—a major discovery recognized by the 2011 Nobel Prize in Physics. New ...

We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These ...

“Under the right conditions, this collapse doesn’t end in a singularity — instead, it bounces and begins expanding again,” said University of Portsmouth professor Enrique Gaztañaga in a statement that ...

“For the last 20 years, people believed that the cosmological constant is positive, and the universe will expand forever,” says Tye, a professor emeritus at Cornell. A positive constant acts like a ...

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