Now physicists from the University of Washington are taking a big swing at answering that question. All matter exerts gravitational force. The more mass the object has, the greater the force. Yet, a ...

Your science textbook likely told you that matter exists in four states. You know them as solid, liquid, gas, and plasma. For generations, this understanding formed the foundation of physics. Now, a ...

Recent scientific discoveries have unveiled a baffling phenomenon: matter vanishing into thin air. This groundbreaking revelation has sparked intense debate and curiosity within the scientific ...

Galaxies are far more than the sum of their stars. Long before stars even formed, dark matter clumped up and drew regular matter together with its gravity, providing the invisible scaffolding upon ...

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: ...

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 ...

WASHINGTON, June 16 (Reuters) - The universe has two kinds of matter. There is invisible dark matter, known only because of its gravitational effects on a grand scale. And there is ordinary matter ...

Researchers using custom fabricated nanostructures that 'trap' light have created a new exotic state of matter with light at room temperature ...

After almost a year of searching, a high-tech instrument buried deep in a South Dakota cavern has turned up no sign of dark matter. Ironically, a team of physicists is pretty excited about it. After ...

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 ...
