Ripples in the fabric of space-time called gravitational waves may be the key to solving the Hubble tension — one of the biggest nagging problems in physics.

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 ...

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 ...

Brown University physics Prof. Stephon Alexander spoke on how the analysis of musical elements can help astrophysicists understand patterns of the universe in his lecture “The Jazz of Physics” ...

Shaped by a different biology or culture, other intelligent civilisations – if they’re out there – might understand the ...

“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 ...

“The new data seem to indicate that the cosmological constant is negative, and that the universe will end in a Big Crunch,” states Henry Tye, Horace White Professor of Physics Emeritus at Cornell.

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 ...

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

UC Santa Cruz physicist Stefano Profumo has put forward two imaginative but scientifically grounded theories that may help solve one of the biggest mysteries in physics: the origin of dark matter. In ...

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 ...
