Physicists are exploring whether hidden dimensions and the shape of space could help explain why fundamental particles have ...

Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current ...

Astronomers around the world are in a bit of a tizzy because they can't seem to agree about how fast the universe is expanding. Ever since our universe emerged from an explosion of a tiny speck of ...

Astronomers at NASA's Chandra X-ray Observatory have found evidence of a particle jet coming from a supermassive black hole in the early universe. The source of the X-ray jet is a quasar, or a ...

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 ...

The W boson, one of the tiniest, most elementary particles in the known universe is causing a big ruckus in the field of particle physics. According to the Standard Model, W bosons (together with ...

Although our universe may seem stable, having existed for a whopping 13.7 billion years, several experiments suggest that it is at risk – walking on the edge of a very dangerous cliff. And it’s all ...

The universe's matter-antimatter asymmetry, where matter significantly outweighs antimatter despite their theoretically equal creation at the Big Bang, remains a major unsolved problem in physics.
