Specifically, physicists and philosophers tend to conflate what it means for something to exist and what it means for ...

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

Light speed would allow instant trips across Earth and minutes to reach the Sun, but even at 300,000 km/s the expanding ...

NASA’s Voyager 1 space probe will continue its almost half-century of service by delivering yet another milestone.

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.

Researchers at the University of Basel have developed a new approach to applying thermodynamics to microscopic quantum systems.

The effect, first predicted over 60 years ago and regarding objects traveling near the speed of light, has been lent support ...

It takes light a single day to travel 16 billion miles. The Voyager 1 probe will need a little longer, just 49 years.

In a cafe at CERN in 1992, three physicists realized they disagreed about how many constants are needed to describe all of nature. A recent paper suggests only one – time – is necessary.
