Ten years ago, scientists heard the universe rumble for the first time. That first discovery of gravitational waves proved a key prediction from Albert Einstein's theory of general relativity and began a new era of astronomy.

Gravity is a ubiquitous part of our daily lives — whether we’re being tragically brought to our knees after tripping on the rug or gleefully jumping from a swing’s apex. But despite how common the experience of gravity is, it remains one of physics ...

The weak gravitational pull on a particle just half the mass of a grain of sand has been measured for the first time. This most precise measurement of its kind is a breakthrough towards the quantum realm and a potential Theory of Everything. Of the ...

Nobel laureate Steven Weinberg was rewarded as well, for his varied and continuing contributions to physics. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. A team of physicists just snared $3 ...

Even teeny objects obey the law of gravity. A gold ball just 2 millimeters wide, with a mass of about 90 milligrams, is now the smallest object to have its gravitational pull measured. Observations of that gold sphere tugging on another similarly sized ...

In the last episode of Cosmos: A Spacetime Odyssey (which you can watch online), the show was trying to make a case for dark matter. Here is what Neil DeGrasse Tyson said about orbiting objects. "In our solar system, the inner most planet, Mercury, moves ...

The movie Gravity had everyone spellbound with its gripping portrayal of spacewalks and the perils astronauts encounter

If you’re superstitious, a black cat in your path is bad luck, even if you keep your distance. Likewise, in quantum physics, particles can feel the influence of magnetic fields that they never come into direct contact with. Now scientists have shown that ...
