Ever wondered what gravity really is? Is it a force, or is there more to it than we know? In this video, we break down the ...

On the 100 th anniversary of Albert Einstein's general theory of relativity, Bennett's book seeks to explain both special and general relativity in a form that a nonexpert could understand. [ Book ...

The general theory of relativity is a remarkably successful model for gravity. However, many of the best tests for it don't push its limits: they measure phenomena where gravity is relatively weak ...

Baumgarte's years of teaching convinced him that students would benefit from a treatise on numerical relativity that explains the science with analogies. The pair's new book starts with a “gentle” ...

The latest results show that alpha is less than 10-8 – a result two orders of magnitude better than from experiments using caesium clocks, and twice as accurate as the previous best limit ...

General relativity is best thought of as a landscape, both literally and figuratively. It is an expanse of concepts that describes all the possible configurations of space and time, and all the ...

An international team led by Japanese researchers has now been able to test Einstein’s theory of general relativity up to 13 billion light-years from Earth, and they found that the theory is ...

In The Perfect Theory, Ferreira masterfully portrays the science and scientists behind general relativity's star-crossed history and argues that even now we are only just beginning to realize its ...

Quantum mechanics and general relativity are the two best theories in physics, but they have never been able to get along. Quantum mechanics successfully describes the world of the very small, ...

Einstein’s general theory of relativity can be summed up in just 12 words: “Space-time tells matter how to move; matter tells space-time how to curve”. But this short description from the ...
