For the first time, a quantum radiation reaction in strong electromagnetic fields has been demonstrated experimentally by ...

No one can question the impact of science on human civilization, and the importance of experimentation in science is equally undeniable. Some experiments confirm what we already know, others suggest a ...

A spacecraft traveling at 99 percent the speed of light toward Alpha Centauri would cross 4.3 light-years in what feels like ...

Scientists observe a visible time crystal for the first time, revealing a phase of matter that repeats patterns through time.

In 1971, graduate student Stuart Freedman and postdoctoral fellow John Clauser took over a room in the sub-basement of Birge Hall at the University of California, Berkeley, and built an experiment ...

Physicists at the UK’s Central Laser Facility have recorded the first observation of quantum radiation reaction, detecting how electrons lose energy in ways that classical physics cannot explain when ...

SCIENTISTS who threw down the gauntlet to physics by reporting particles that broke the Universe's speed limit say they're revisiting their contested experiment. "The new test began two or three days ...

The long-awaited first results from the Muon g-2 experiment at Fermi National Accelerator Laboratory show fundamental particles called muons behaving in a way that is not predicted by scientists’ best ...

A virtual laboratory under development at the University of North Carolina at Greensboro aims to let students experiment with physics concepts without physically being in a lab. Computer simulations ...

Preliminary results from two experiments suggest something could be wrong with the basic way physicists think the universe works, a prospect that has the field of particle physics both baffled and ...
