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 ...

it did not explain the nature of gravity itself. Einstein knew that his theory of special relativity was partial. It couldn’t ...

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 ...

Special relativity tells us motion warps space and ... making things appear to accelerate towards them. That explains why we feel a downwards pull towards Earth and why Earth orbits the sun.

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 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, plus ...

In fact, length contraction in special relativity explains how electromagnets work. A magnetic field is just an electric field seen from a different frame of reference. So, when an electron moves ...

General relativity describes gravitation in a geometrical framework generalizing special relativity and ... a phenomenon that is difficult to explain with existing models.
