For this reason, in the corridors of particle physics departments, it is usually said that the universe is not unstable but rather "meta-stable," because the world's end will not happen anytime soon.

When massive stars reach the end of their life cycles, they often explode in dramatic cosmic events called supernovae. These ...

The newly found antiparticle, called antihyperhydrogen-4, could have a potential imbalance with its matter counterpart that may help scientists understand how our universe came to be.

Particle physics describes the universe at the smallest scale. This includes subatomic particles, like protons and neutrons, as well as elementary particles, like quarks and electrons, which make ...

This particle was spotted by the Cubic Kilometer Neutrino Telescope (KM3NeT), a collection of light-detecting glass spheres on the floor of the Mediterranean Sea, on February 13, 2023, according ...

Supernovas can become some of the most powerful particle colliders in the universe — but only if they pass a whole lot of gas before they explode, new research finds. For almost a century, astronomers ...

helping us discover the physics that led to the universe we live in today. Differences between matter and antimatter have previously been observed in the behaviour of another type of particle, mesons, ...

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 ...
