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

For close to a century, scientists have been trying to marry Albert Einstein’s General Theory of Relativity and quantum ...

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 ...

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 ...

Physicist Brian Cox has rarely been shy about his enthusiasm for big, difficult ideas, but his reaction to a recent quantum ...

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 ...

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 ...

Canseco kicked off his bizarre tirade against gravity with a cryptic tweet on Monday. On Tuesday Canseco shared his theories on how gravity in ancient times was “much weaker” because how else could ...

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 1915, the universe was small and static. Space was smooth. Gravity pulled things to the ground. At least that’s the way it was in the minds of all but one exceptional physicist — Albert Einstein.

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 ...
