By studying galaxy clusters separated by hundreds of millions of light-years, Penn physicist Patricio Gallardo and collaborators show that the laws of gravity described by Newton and Einstein still ...

Here’s what you’ll learn when you read this story: In 1687, English physicist Isaac Newton published his famous Law of Universal Gravitation. The idea that all objects attract in proportion to their ...

From Newton’s apple to Einstein’s spacetime, gravity has been tested on scales from sub-millimeter experiments to galaxy clusters millions of light-years apart. Recent studies confirm its laws hold ...

In what the team describes as the largest-scale probe of gravity to date, they found that the force weakens with distance ...

Gravity, as most people understand it, is the familiar force that pulls a falling apple toward Earth. But for astronomers and theoretical physicists, it is also a vexing invisible architect that ...

Cosmic viewer The Atacama Cosmology Telescope in Chile was used by the team to observe gravitational interactions between ...
