The parabolic flight travels up and down several times on a trajectory resembling an arch, providing 22 seconds of zero ...

The best way to find buried treasure may be with a quantum gravity sensor. In these devices, free-falling atoms reveal subtle variations in Earth’s gravitational pull at different places. Those ...

You might expect that, all these years after Newton, we might have a good measure of his gravitational constant, G. As the authors of a new paper on the topic note, there are plenty of reasons to want ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to be folded neatly into the quantum rules that govern the rest of nature. Now a convergence of bold ...

Alex Chadwick talks Ira Flatow, host of NPR's Talk of the Nation Science Friday, about new examinations of the theories of Galileo and Isaac Newton relating to gravity. This is DAY TO DAY. I'm Alex ...

In 1916, Albert Einstein predicted the existence of gravitational waves when he proposed his theory of general relativity. Einstein figured that any object with mass creates a kind of signal, rippling ...

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," ...

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, ...

Purists insist that the spacetime ripples just discovered by the Advanced LIGO observatories should be called “gravitational” waves. Which in itself is just a shorthand way of saying radiation of ...

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 ...

Hey, how do you feel about gravity? Seems real, right? Knock stuff over, it falls down. But according to new research, that might just be because we all live in a holodeck. This requires some ...

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 ...
