Discover how Einstein’s theory of special relativity reshaped physics by linking space, time, mass, and energy in a universe governed by the speed of light. Albert Einstein's 1905 theory of ...

Einstein’s motivation to understand the nature of light began when he was just 16 years old. His theory of special relativity ...

The Terrell-Penrose effect, predicted in 1959, suggests that objects moving at speeds close to that of light appear rotated.

Einstein's theory is divided into special and general relativity. Special relativity came first and is based on the speed of light being constant for everyone. That may seem simple enough ...

Albert Einstein. He published the first part of his theory — special relativity — in the German physics journal Annalen der Physik in 1905 and completed his theory of general relativity only ...

General relativity is physicist Albert Einstein's understanding of how gravity affects the fabric of space-time. The theory, which Einstein published in 1915, expanded the theory of special ...

Once again, scientists have shown that Albert Einstein's theory of special relativity is right — this time, thanks to a particle detector buried deep beneath Antarctica. Scientists from the 1 ...

First came a screening of a new NOVA special, to be aired nationally on PBS on Wednesday, the 100 th anniversary of Albert Einstein’s General Theory of Relativity. Then came the obligatory panel ...

The theory – now known as special relativity – was hardly defined in this short article. It said that a “Prof. Einstein of the University of Zurich” as well as Max Planck had argued ...

Albert Einstein's theory of general relativity—which explains gravity as the product of the distortion of space and time—may not be universally applicable. This is the conclusion of physicists ...
