A 'boom' of light that appears when a particle exceeds the speed of light set by a medium could, in other contexts, signal a ...

A material cooled near absolute zero produced an electrical signal that physics said should not exist, revealing a new kind ...

Researchers led by Rice University's Guido Pagano used a specialized quantum device to simulate a vibrating molecule and ...

Flashes like Cherenkov radiation in space may reveal negative-energy ghosts, hinting at gaps in gravity theories.

Imagine a juggler tossing balls into the air. The art of juggling is a dance between motion and pause, where the ball’s speed ...

The rapid acceleration of the universe’s expansion continues to challenge our understanding of fundamental physics. Why the universe is expanding faster and faster remains one of the most intriguing ...

Focused Energy is developing a commercial system for generating energy from the laser-driven fusion of hydrogen isotopes.

Scientists in Finland transmitted electricity through air using sound waves, lasers, and radio frequencies, creating ...

An electric charge (like a proton) creates an electric field in the region around it. This field points away from positive charges and decreases in strength as it gets farther away from the charge.

Solve a basketball jump physics problem by tracking how mechanical energy changes from takeoff to peak height. This video explains kinetic energy, gravitational potential energy, and energy ...

Physics is the study of the underlying laws and mechanisms explaining how the universe works. Most of what we do in daily life is based on a principle or law of physics—dealing with forces, motion, ...
