Question

What's the point of the Hoyle–Narlikar theory of gravity?

Answer 1

Many extensions of general relativity have been proposed, to solve various problems or expand it's range as a theorem. The one of these that caught my eye most recently is Hoyle–Narlikar theory, a theory of gravity that reduces to GR in the limit of a smooth fluid model of particle distribution.

My question is simply, what's the goal of this theory? What holes is this theory trying to fill, or what questions is it trying to answer? It claims to give a theoretical backing to how matter is creating from nothing, but that seems to be an "auxiliary" part of the theory that is usually omitted because it does not agree with WMAP data.

EDIT: I mentioned this quickly with a professor who told me that, if correct, it gives boundary conditions on Einstien's field equations. What exactly does this mean, and how does this theory accomplish it
