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 ...

The regular matter that makes us, planets, stars, and galaxies is about 5 percent of the matter-energy content of the ...

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 ...

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 ...

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 … ...

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 ...

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 ...

By combining negative mass and matter creation, dark matter and dark energy can be unified into one single substance—a "dark fluid." One of the reasons we know dark matter exists is its ...

(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 ...
