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 ...

Albert Einstein had described the special theory of relativity in 1905. The result of Einstein's thinking about light, this theory introduced brand-new ideas to science. It opened up an entire ...

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 ...

The discovery in 1998 that the Universe is expanding faster over time shook the foundations of cosmology. This finding ...

“The chief attraction of the theory lies in its logical completeness,” wrote Albert Einstein after publishing his general theory of relativity in 1915. “If a single one of the conclusions ...

On 25 November 1915, Albert Einstein presented his general theory of relativity at the Prussian Academy of Sciences. This theory is still considered to be the most important idea in modern physics.

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

Indeed, I found that the new formula could recover the correct ... theory might unveil a hitherto neglected effect of Einstein's relativity theory. For example, in analogy with length contraction ...

For over a century, Einstein's general theory of relativity has been key to understanding gravity. But new research suggests this theory "glitches" in the farthest reaches of space. That doesn't ...

Einstein’s discoveries led to modern-day inventions like paper towels, solar power, stock market forecasts and laser pointers, but his theory of general relativity is often regarded as his most ...
