Description
General relativity has been tested in the solar system and with other astrophysical observations and passed all tests with flying colours. However, these were essentially tests of the vacuum Einstein equations. Cosmology is different. Not only do we test GR on much larger scales, but it is also a very essential non-vacuum solution of the theory.
Observing LSS we cannot only measure the density distribution and velocities, but, when considering relativistic effects, we can also measure the metric. In my talk I shall present a few examples on how LSS observations can provide tests of General Relativity.
