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

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

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth space-time with the jittery world of quantum mechanics. A new wave of ...

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 ...
