In the realm of physics, the speed of light is considered one of the most fundamental constants in the universe, dictating the structure of time and space as we know it. But what if this cornerstone ...

Addressing a controversy first raised around 1910, two physicists have performed experiments with the aid of an engineer that validate anew the special theory of relativity’s limitations on the speed ...

Light is the fastest-moving thing in the universe. So what would happen if the speed of light were much, much slower? In a vacuum, the speed of light is about 186,000 miles per second (300,000 ...

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 ...

For the first time, physicists have simulated what objects moving near the speed of light would look like — an optical illusion called the Terrell-Penrose effect. When you purchase through links on ...

In the past few years, scientists have found ways to make light go both faster and slower than its usual speed limit, but now researchers at the University of Rochester are publishing a paper on May ...

GENEVA (Reuters) - An international team of scientists said on Thursday they had recorded sub-atomic particles traveling faster than light -- a finding that could overturn one of Einstein's ...

A nanostructure made of silver and an atomically thin semiconductor layer can be turned into an ultrafast switching mirror ...

Researchers in Germany have unveiled an ultra-fast light switch made of very thin semiconductor ...
