An international team of physicists discovered the largest-ever merger of 2 black holes through a phenomenon known as ...

It was in 1980 that John Anderson first wondered if something funny was going on with gravity. The Jet Propulsion Laboratory physicist was looking over data from two Pioneer spacecraft that had ...

Gravity is the reason things with mass or energy are attracted to each other. ... Why does gravity pull us down and not up? – Gracie, age 9, Brookline, Massachusetts.

Here's why the force of gravity pulls us down rather than up. The answer involves Einstein and the bendy realm of space-time.

Perhaps surprisingly, gravity is the weakest of the four fundamental forces and the hardest to measure here on Earth. Now, physicists in Austria have made the smallest measurement of gravity so ...

And sure enough, the team measured a weak gravitational pull of just 30 attonewtons (aN) acting on this particle at points that corresponded to when the larger weight was closest to it.

Gravity is the kind of enthralling, all-encompassing, ... No film since 2001: A Space Odyssey in 1968has captured such a vivid reality outside Earth's gravitational pull.

Book Review: Feeling Gravity’s Pull Of the 100,000,000 black holes presumed to exist in our galaxy, we’ve been able to detect only 30. Atacama Desert, Chile. Dave Yoder/National Geographic. By .

In this expression, G is the universal gravitational constant with a value of 6.67 x 10-11 newtons x meters 2 /kilogram 2. This is a super small value and shows you why the gravitational force is ...
