Physicists are always searching for new theories to improve our understanding of the universe and resolve big unanswered questions. But there's a problem. How do you search for undiscovered forces or ...

Physics is supposed to be predictable. Drop a ball, and gravity pulls it down. Heat water, and it boils. Light travels in straight lines. Yet throughout history, scientists have encountered ...

A recent experiment points the way toward making the intense, energetic beams of positrons needed for next-generation electron–positron colliders. An artist’s conception of a detector harvesting ...

Magnetic monopoles are elementary particles with isolated magnetic charges in three dimensions. In other words, they behave as isolated north or south poles of a magnet. Magnetic monopoles have ...

A team of physicists and engineers at Princeton Plasma Physics Laboratory built a twisting fusion reactor known as a stellarator that uses permanent magnets, showcasing a potentially cost-effective ...
