The Universe should not exist. At least, not according to simple physics. After the Big Bang, equal parts matter and antimatter should have formed, then wiped each other out in flashes of energy.

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 ...

MicroBooNE's results show no evidence for sterile neutrinos, strengthening support for the standard three-flavor neutrino model and adding complexity to earlier unexplained anomalies.

Astronomers found evidence that dark matter and neutrinos may interact, hinting at a "fundamental breakthrough" that ...

In a rare global collaboration, scientists from Japan and the United States joined forces to explore one of the universe’s deepest mysteries — why anything exists at all. By combining years of data ...

We preselected all newsletters you had before unsubscribing.

But only in the last 70 years have we known for certain they were there. In 1956, physicists Clyde Cowan and Frederick Reines ...

Here’s what you’ll learn when you read this story: It used to be thought that bizarre interactions between subatomic particles known as neutrinos could be explained by another type of neutrino. The ...

For three decades, a riddle has followed neutrinos, the near-weightless particles that stream through Earth by the trillions each second. They change identities as they fly, shifting among three known ...

There's a significant imbalance between matter and antimatter in our universe, but a strange particle called "the Majoron" could finally explain it, an audacious new study suggests. When you purchase ...

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.
