A dark point inside a beam of light should not be much of a traveler. Yet in a new experiment, some of those points appeared ...
Space and time looked settled, at least in broad outline. Einstein’s special relativity gave physics a durable framework for ...

Einstein’s lost theory said gravity changes speed of light and a new experiment claims it was right
Albert Einstein postulated in his 1905 theory of special relativity that the speed of light in a vacuum is constant. Ever ...
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 ...

A Physical Warp Drive Was Supposed to Be Impossible. Then These Scientists Found a Loophole.
Humans are one (small) step closer to traveling at faster-than-light speeds.
When an object moves extremely fast – close to the speed of light – certain basic assumptions that we take for granted no longer apply. This is the central consequence of Albert Einstein's special ...
On one hand, the speed of light is just a number: 299,792,458 meters per second. And on the other, it’s one of the most important constants that appears in nature and defines the relationship of ...
