f(R) Theories of Gravity

Jim and Randy discuss gravitational theories that modify general relativity by changing the action using a polynomial dependence on the Ricci scalar. Although not physically motivated, some of these theories produce effects similar to those of dark matter, dark energy, and cosmological constants.



1. "f(R) Theories of Gravity, by Thomas Sotiriou and Valerio Faraoni". The basis for this discussion and the next program's, as well.
