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 ...

Casimir cavities are mysterious spaces between microscopic metal plates in a vacuum. Areas of diminished energy between the plates cause them to push toward each other, as if trying to fill the ...

The constancy of the speed of light is a pillar of modern physics, but questions persist about its absolute universality. Advanced theories, seeking to unify general relativity and quantum mechanics, ...

Space — the final frontier. These are the words that introduce every episode of classic "Star Trek," the show that essentially popularized the concept of traveling the stars at the speed of light – or ...

Physicists artificially slowed down time to reveal the bizarre Terrell-Penrose effect, a consequence of special relativity. This image from the experiment shows a sphere seemingly moving at 99.9 ...

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 ...

Imagine you’re in a car driving across the country watching the landscape. A tree in the distance gets closer to your car, passes right by you, then moves off again in the distance behind you. Of ...

The great Galileo Galilei (1564-1642) tried to measure the velocity of light by means of lantern signals between mountain tops. Naturally he failed. Light travels about 186,270 miles (more than seven ...
