But as usual in science, there's more to the story. Forces and Fields On human scales of mass and distance, matter obeys the laws of motion described by Sir Isaac Newton.

Researchers using data from NASA's Fermi Gamma-ray Space Telescope have set the most stringent limit yet for the mass of dark matter. The new findings throw into question recent findings from ...

Physicists searching -- unsuccessfully -- for today's most favored candidate for dark matter, the axion, have been looking in the wrong place, according to a new supercomputer simulation of how ...

Physicists working at the CERN particle physics lab said they detected a slight but significant difference in how particles ...

The new estimate helps pin down how heavy its particles could be — with implications for what the mysterious stuff actually is. The research sharply narrows the potential mass of dark matter ...

No matter what you do, matter can neither be created nor destroyed. This property of the universe is called the law of conservation of mass.

Centuries of astronomical observation and technological advances have revealed a lot about the Universe we all call home, but it’s also raised plenty of new … ...

Around 68 percent of the remaining mass is dark energy, with just five percent left to ordinary “baryonic” matter, aka the objects we directly observe, like planets and stars.

Antimatter is anti- a lot of things, but it’s not supposed to be antigravity. An antimatter particle does have the opposite electric charge of its ordinary matter counterpart. But the mass of ...

(via PBS Space Time) Fermilab physicists really care about the mass of the W boson.They spent nearly a decade recording collisions in the Tevatron collider and another decade analysing the data. This ...

But there were no sightings of the elusive particles in a mass range between 2.81 millionths and 3.31 millionths of an electron volt (between about 5.5 trillionths and 6.5 trillionths of an ...
