Gravity is the reason things with mass or energy are attracted to each other. It is why apples fall toward the ground and planets orbit stars. Magnets attract some types of metals, but they can also ...

For centuries, gravity has been the cornerstone of physics—but what if it’s not the universe’s true force? The Electric Universe theory claims that invisible cosmic currents shape stars, planets, and ...

As far as physicists have been able to determine, nature speaks two mutually unintelligible languages: one for gravity and one for everything else. Curves in the fabric of space-time tell planets and ...

Over the past few decades, the idea that gravity is not a fundamental interaction but is instead caused by the increase of entropy has become increasingly popular in the worl ...

Physics is the study of the underlying laws and mechanisms explaining how the universe works. Most of what we do in daily life is based on a principle or law of physics—dealing with forces, motion, ...

Traditional black holes, as predicted by Albert Einstein's theory of General Relativity, contain what are known as singularities, i.e., points where the laws of physics break down. Identifying how ...

The breakthrough could suggest a way to study 'quantum gravity,' the missing link between quantum physics and Einstein's general relativity in the lab. When you purchase through links on our site, we ...

It was already a mind-bending shift, last century, to go from Isaac Newton’s absolute space and universal time to Albert Einstein’s four-dimensional space-time, which is dynamic, flexible, sensitive ...
