In this video, we explore five key areas of physics: **Classical Mechanics:** Newton’s second law (F = ma) explains the relationship between force, mass, and acceleration. The law of universal ...

Dark energy, the mysterious force that's driving the accelerating expansion of the universe, may not actually exist, scientists say. Their research has brought into question one of the cornerstones of ...

For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the bending of space and time. Quantum mechanics governs the world of particles ...

A look at why quantum physics works well in theory, but still struggles to explain dark energy.

Dark energy—the term used to describe whatever is causing the universe to expand at an increasing rate—is one of the universe’s greatest mysteries. The most widely accepted theory currently suggests ...

The goal of high energy physics (also known as particle physics) is to determine the most fundamental building blocks of matter and to understand the interactions between these particles. The ...

Dark centre? A simulated version of the Milky Way galaxy. (Courtesy: AIP/ A. Khalatyan) Astronomers have long puzzled over the cause of a mysterious “glow” of very high energy gamma radiation ...
