An artist's concept of twisted space-time around Earth. Albert Einstein's theory of general relativity is a monumental achievement of human ingenuity, creativity and perseverance — to say the least.

(Nanowerk News) Albert Einstein, one of the most celebrated modern scientists, proposed the revolutionary theory of special relativity over a century ago. This theory forms the basis of most of what ...

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 ...

The answer comes from a counterintuitive result of special relativity, a field of physics which is notoriously difficult to ...

The European Space Agency (ESA) has launched one of its most precise science experiments to date — the Atomic Clock Ensemble in Space (ACES)—to the International Space Station (ISS). This is no ...

Achim Peters of the University of Konstanz in Germany and colleagues have used a super-stable laser standing wave to check Einstein's special theory of relativity three times more accurately than ...

One hundred years ago today, in the wake of the first World War, a British astronomer watched a solar eclipse for signs that a German physicist may have been right about warps in the universe. The ...

One hundred years ago, at the beginning of 1919, few people outside Germany had ever heard of Albert Einstein. By the year’s end, however, he had become a world-wide celebrity and a symbol of human ...

Researchers at Osaka University demonstrate the relativistic contraction of an electric field produced by fast-moving charged particles, as predicted by Einstein’s theory, which can help improve ...
