f(R) Theories of Gravity
from Physics Frontiers · host Jim Rantschler
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. Show notes: http://frontiers.physicsfm.com/9
