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

Learn the key physics definitions of position, displacement, velocity, and acceleration explained clearly and simply. This quick breakdown helps build a strong foundation for understanding motion in ...

In high-intensity laser–matter interactions, including laser-induced particle acceleration, physicists generally want to work ...

The discovery of the first interstellar visitor, a space rock called ‘Oumuamua, sent waves of excitement across the scientific community. It also started a mystery. The object had all the ...

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 ...

Scientists have come a step closer to understanding how collisionless shock waves—found throughout the universe—are able to accelerate particles to extreme speeds. The research, published in Nature ...
