Scalar-tensor theories generalise Einstein’s general relativity by introducing one or more scalar fields that couple nonminimally to the metric. These scalar degrees of freedom can mediate long-range ...

Alena Tensor completely reverses this approach. It is much easier now to describe gravity in flat space-time in a way that mathematically reproduces general relativity and then uses the known tools of ...

After Albert Einstein published his special theory of relativity in 1905, he spent the next decade trying to come up with a theory of gravity. But for years, he kept running up against a problem. He ...
