The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study ...

High energy proton collisions can be pictured as a roiling sea of quarks and gluons, including short lived virtual particles. At first glance, this ...

Inside high-energy proton collisions, quarks and gluons briefly form a dense, boiling state before cooling into ordinary ...

For more than a century, thermodynamics has described how heat flows and engines run, while quantum mechanics has ruled the strange behavior of atoms and photons. Physicists have long suspected that ...

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 ...
