GRAVITY, is a 4-beam interferometric combiner at VLT-I operating in K-band. It is fully described on these pages. Deadline for GRAVITY SV proposals is March 25 2016 18:00 (CET). Proposals need to be ...

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 ...

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, ...

It’s hard to imagine a more fundamental and ubiquitous aspect of life on the Earth than gravity, from the moment you first took a step and fell on your diapered bottom to the slow terminal sagging of ...

How are controversial ideas handled by modern science? A common charge leveled against science (generally by those who are unhappy with its conclusions) is that the only way to get funding or continue ...

A little more than a year ago, humanity got its first good look at the most mysterious object of the vast universe. For the first time, astronomers had imaged a black hole, which was lurking on the ...

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 ...

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 ...

Artificial gravity has long been the stuff of science fiction. Picture the wheel-shaped ships from films like 2001: A Space Odyssey and The Martian, imaginary craft that generate their own gravity by ...

After more than 15 productive years in orbit, the U.S./German GRACE (Gravity Recovery and Climate Experiment) satellite mission has ended science operations. After more than 15 productive years in ...

A young English scientific worker, one R. H. Tate of West Hartlepool, Durham, last week summoned witnesses into his laboratory’s secrecy, showed them a sheet of aluminum-like metal on the floor, held ...

Gravity is tough. It took Newton a long time to crack it and a lot of Newtonian physicists a hundred years to confirm Einstein’s gravitational theories. And that’s the naturally occurring stuff.
