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

Physicists have taken a gemstone better known for engagement rings and turned it into a laboratory for one of the strangest ...

A simple explanation of dark matter and antimatter, how they differ, how scientists study them, and why both are important to understanding the universe.

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: ...

Normal matter – which makes up everything we see and touch – isn’t the only type of matter present in the universe.

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 ...

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 ...

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 ...

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.

Dark matter, the mysterious substance that exerts gravitational pull but emits no light, might really consist of vast concentrations of ancient black holes created at the very start of the universe, ...

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 ...

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 ...
