In Nature for October 14, 1967, Professor H. Dingle argued that the special theory of relativity is incorrect, and Professor W. H. McCrea put an opposing view. Some correspondence on the same ...

Ten years before general relativity, Einstein came up with special relativity, which explained the relationship between space and time – and how they are related to each other. 'Special' means ...

In the first study of its kind at the Large Hadron Collider (LHC), the CMS collaboration has tested whether top quarks adhere to Einstein's special theory of relativity. The research is published ...

His theory of special relativity stemmed from his desire to understand the nature of light and what would happen to objects ...

Special relativity is beyond weird. Among its many statements are that moving clocks run slow and that moving rulers shrink. But how are we supposed to make sense of this? To understand the ...

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 ...

It is an extension of Einstein’s special theory of relativity – but such a massive one that it took him 10 years, from 1905 to 1915, to get from one to the other. Special relativity tells us ...

Albert Einstein's general theory of relativity is one of the towering achievements of 20th-century physics. In our introduction to general relativity, we explain how this theory developed ...

General relativity describes gravitation in a geometrical framework generalizing special relativity and classical mechanics. This term includes theoretical studies of gravity, experimental studies ...

Here are a few thought experiments that demonstrate some of Einstein's most groundbreaking discoveries, including his special and general theories of relativity. What would happen if you chased a ...

Observing the effects of special relativity doesn't necessarily require objects moving at a significant fraction of the speed of light. In fact, length contraction in special relativity explains ...
