Matter is all around us. Everything that has weight and takes up space is matter. Matter exists mostly in four basic states: solid, liquid, gas, and plasma. And it all has to do with atoms. Science ...

For more than a century, schoolbook physics has divided matter into neat categories like solid, liquid, gas, and plasma. A ...

In middle and high school, most people learn about the three states of matter we interact with in our everyday lives: solid, liquid and gas. Some students may have even been introduced to the idea of ...

Fish school, insects swarm and birds fly in murmurations. Now, new research finds that on the most basic level, this kind of group behavior forms a new kind of active matter, called a swirlonic state.

The fifth state of matter—the ultracold Bose-Einstein condensate (BEC)—has been an invaluable tool in unlocking the secrets ...

Dark matter, it seems, has been clinging to galaxies for a very long time. Most galaxies that existed 10 billion years ago had about as much dark matter as galaxies do today, contradicting earlier ...

Only recently have scientists realized that most of the universe is neither gaseous, liquid or solid. It is plasma, a lively, tricky, often dangerous state of matter whose distinctive characteristic ...

At the end of a lecture on astronomy, describing how the planets orbit the Sun, a little old lady at the back of the room stood up and said: "What you've told us is all rubbish. The world is really a ...

Physicists have taken a gemstone better known for engagement rings and turned it into a laboratory for one of the strangest ideas in modern physics, a phase of matter that repeats in time instead of ...

The universe is packed with riddles, but few are as stubborn or as fascinating as dark matter. First proposed in 1933 by astronomer Fritz Zwicky, this elusive substance refuses to play by the rules: ...

There's a lot of matter to go under the cosmic bridge yet, but a new theory suggests that 95 percent of the universe is filled with a weird "dark fluid." Jackson Ryan was CNET's science editor, and a ...

NASA's Hubble Space Telescope captures the magnificent starry population of the Coma Cluster of galaxies, one of the densest known galaxy collections in the universe — and where the effect of dark ...
