Physicists in Toronto observe quantum “negative time”: a pulse of light appears to leave before entering atoms.

Quantum physics is the realm of the strange. And one of the strangest discoveries in the field is also one of the most fundamental: Particles fired at barriers with two slits in them can act like ...

Scientists for the first time managed to simulate what objects moving near the speed of light looked like, in an optical ...

The most beautiful experiment in physics, according to a poll of Physics World readers, is the interference of single electrons in a Young’s double slit. Robert P Crease reports Simply beautiful – the ...

Scientists at CERN, the famous Geneva-based physics lab, have just called into question one of the most hallowed equations in physics: E = MC2. Scientists, the AP explains, have clocked subatomic ...

Physics experiments have changed the world irrevocably, altering our reality and enabling us to take gigantic leaps in technology. From ancient times to now, here's a look at some of the greatest ...

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 ...

Ultrathin structures that can bend, focus, or filter light, metasurfaces are reshaping how scientists think about optics.

A new study published in the journal Physics Letters B claims that dark matter can be detected through a "fingerprint" in red ...

A twist in the universe's first light could hint that scientists need to rethink physics. A pair of Japanese scientists looked at the polarization or orientation of light from the cosmic microwave ...

For the first time, physicists have simulated what objects moving near the speed of light would look like — an optical ...

From the discovery of gravity to the first mission to defend Earth from an asteroid, here are the most important physics experiments that changed the world. When you purchase through links on our site ...
