The principle of relativity, as initially described by Galileo, posits that the laws of physics remain consistent regardless of an observer's relative motion. Einstein's special relativity ...

Time travel has long been a staple of science fiction, captivating imaginations with the possibility of moving through time as easily as we travel through space. However, the question remains: how ...

Faster-than-light (FTL) travel is a concept that has long captivated both the scientific community and science fiction enthusiasts. In a cosmos where light speed is viewed as the ultimate velocity ...

How do we know the speed of light – and why does it have a speed limit at all? Leah Crane explores the history of one of the ...

Scientists have taken one more step down the very long road to time travel. A new paper combines the Alcubierre “warp” drive with the idea of “controlled closed timelike curves.” Though far out, ...

If travel to distant stars within an individual’s lifetime is going to be possible, a means of faster-than-light propulsion will have to be found. To date, even recent research about superluminal ...

Science decided to be unfun this morning. Physicists at Hong Kong University of Science and Technology demonstrated that a single photon cannot be accelerated beyond the speed of light. This implies ...
