Einstein’s special relativity, which he formulated in his “miracle year” of 1905, was a theory that revolutionised our ideas of space and time – and ultimately paved the way for some even ...

(Courtesy: Dominik Hornof et al., "A Snapshot of Relativistic Motion: Visualizing the Terrell Effect" 10.48550/arXiv.2409.04296, CC-BY 4.0) A counterintuitive result from Einstein’s special theory of ...

Einstein received the Nobel Prize for one of the other ideas, but the special theory of relativity has since become the most well-known, perhaps of his career or even the entire field of physics!

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 ...

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 ...

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 ...

Einstein's special theory of relativity, published a hundred years ago, also revealed that energy and mass are two sides of the same coin, forever linked in his famed equation E = mc².

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 ...
