Gravity is usually presented as the most familiar of nature’s forces, the quiet background pull that keeps feet on sidewalks and planets in orbit. A growing group of physicists is now treating that ...

If true (and it’s a pretty big “if”), Vopson’s new gravitational study would shake the foundations of the currently accepted view of the universe. In his paper, Vopson writes that his new work could ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth ...

Heading into space means leaving Earth's gravity behind. Astronauts floating around on the International Space Station might look like they're having fun in the weightless environment, but a lack of ...

Engineers have designed a compact, battery-powered radio probe that could help unlock the secrets of alien planets. The proposed small probe, known as the Gravity Imaging Radio Observer (GIRO), would ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. The idea of gravity as we know it has been around for a long time ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...

What could be more familiar than gravity? Drop something and gravity pulls it to the floor, right? And in school we learn that gravity is what guides the moon in orbit around Earth, and Earth in its ...

If you want to understand gravity, it makes sense to study black holes. Nowhere else can you find so much gravity so conveniently compacted into such a relatively small space. In a way, in fact, black ...

In the April 1981 issue of Popular Science, we explored the many initiatives and techniques used in the exciting hunt for sensing gravity waves, then out of reach. By Bill Gourgey Published May 18, ...

With the astronaut flick Gravity dominating box offices and dinner table conversation, Science Friday brings in the experts to fact-check. In our first installment of "Science Goes to the Movies," ...

‘Gravity’ is back in the headlines again. The film, starring Sandra Bullock and George Clooney, is up for a handful of Academy Awards this year, including Best Picture, Best Director, and Best Actress ...
