(CNN) — A mysterious astronomical object merged with a black hole 780 million light-years away and created gravitational waves that could be detected on Earth. The object exists inside what scientists ...

At the end of the 18th century, the British scientist Henry Cavendish measured the force of gravity between two objects for the first time in a laboratory. The objects in question were lead balls, one ...

The object, which falls right within the mass-gap range, sheds light on a long-sought, murky realm. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it ...

A fundamental constant that sets the size of the gravitational force between all objects has finally been pinned down using the quirky quantum behavior of tiny atoms. The new results could help set ...

In any direction! The distance between the Earth and the Sun is a careful balance between the mass of the Earth, the mass of the Sun, the speed with which the Earth orbits the Sun, and the strength of ...

It's fun to think about how we know stuff. For instance, the sun has a mass of about 2 x 10 30 kilograms. That is such an enormous mass that it's difficult to comprehend. And if it's so difficult for ...

After decades of anticipation, we have directly detected gravitational waves—ripples in spacetime traveling at the speed of light through the universe. Scientists at LIGO (the Laser Interferometic ...

Researchers have succeeded in measuring the gravitational field of a gold sphere, just 2 mm in diameter, using a highly sensitive pendulum - and thus the smallest gravitational force. The experiment ...

Ripples in space-time point to the merger of a neutron star with another mystery object. The object, which falls right within the mass-gap range, sheds light on a long-sought, murky realm. When you ...
