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 ...

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

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” ...

The Universe is expanding, but exactly how fast is a contentious question. Two different methods of measurement return two very different speeds – and as the measurements become more precise, each ...

“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 ...

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 ...

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 ...

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 ...
