Shattered glass does not leap back into your hand. Smoke from a match does not gather itself and crawl back inside. In ...

It is thought that the earliest spark of a lightning bolt could arise directly from charged ice crystals. Yet the exact ...

A single green laser, a glass bead smaller than a bacterium and a lab in Austria are helping you see lightning in a new way.

We’re used to seeing ever greater particle accelerators — colossal machines sprawling across landscapes, built to reveal the ...

A scientist analyzing Fermi telescope data found a strange glow around the Milky Way that looks like it could be coming from ...

Physicists tested light speed using cosmic gamma-ray bursts. Study confirms Einstein's prediction that all light colors travel at same speed.

Scientists may have "seen" dark matter for the first time, thanks to NASA's Fermi gamma-ray space telescope. If so, this ...

In the early 1930s, Swiss astronomer Fritz Zwicky observed galaxies in space moving faster than their mass should allow, ...

A team of astronomers say they've made the first ever detection of dark matter by examining gamma rays near the center of the ...

Physicists using near-absolute-zero detectors have reached unprecedented sensitivity in the hunt for light dark matter. A ...

Physicists have demonstrated with unprecedented accuracy that the speed of light remains constant. In 1887, a landmark physics experiment was carried out by American researchers Michelson and Morley.

Nearly a century after astronomers first proposed dark matter to explain the strange motions of galaxies, scientists may finally be catching a glimpse of it. A University of Tokyo researcher analyzing ...
