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 ...

Add Yahoo as a preferred source to see more of our stories on Google. Spiral galaxies, like Messier 77 shown here, helped astronomers learn about the existence of dark matter. NASA, ESA & A. van der ...

Antimatter, the elusive counterpart to the matter that makes up everything around us, has intrigued scientists for decades. Recent breakthroughs have begun to unravel the mysteries surrounding ...

Two new studies highlight the enigmatic nature of antimatter, revealing its potential role in both understanding the universe's origins and unlocking the secrets of particle physics. Reading time 3 ...

In the Big Bang, matter and antimatter should have been created in equal amounts. But fast forward 13.8 billion years to the present day, and the universe is made almost entirely of matter, so ...

Scientists studying the tracks of particles streaming from six billion collisions of atomic nuclei at the Relativistic Heavy Ion Collider (RHIC) -- an 'atom smasher' that recreates the conditions of ...

If the Big Bang had played fair, you wouldn’t be reading this. Nothing would exist—not stars, not cheese, not you. That’s because, in theory, the universe should’ve created equal amounts of matter and ...

In experiments at the Brookhaven National Lab in the U.S., an international team of physicists has detected the heaviest “anti-nuclei” ever seen. The tiny, short-lived objects are composed of exotic ...

Our universe is filled with particles, such as electrons and protons, which make up all the stuff on our planet and beyond: animals, plants, people, planets, asteroids, stars, gas clouds, and galaxies ...
