What if the universe remembers? A bold new framework proposes that spacetime acts as a quantum memory. For over a hundred ...

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 ...

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 ...

Progress in the foundations of physics is moving slowly. And yet it moves. Today I look at the five biggest problems in ...

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 ...

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 ...

The halls of science, known for prim propriety and careful debate, are feuding. A new theory of gravity challenges Einstein's general relativity, our current understanding of that thing that keeps our ...

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 ...

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, ...
