Einstein’s theory of gravity — general relativity — has been very successful for more than a century. However, it has theoretical shortcomings. This is not surprising: the theory predicts its own ...

In a 1923 book called “The Principle of Relativity,” Albert Einstein seemed to call out to better-equipped scientists of the future to establish the truth of his mind-bending theoretical work. “Apart ...

The accelerating expansion of the universe could be explained by modifying general relativity so that gravity has mass – or so thinks a small group of physicists. Matthew Francis reports What lies ...
