Hello All,(adsbygoogle = window.adsbygoogle || []).push({});

I am stuck up in a concept, not on maths part.

Gravitational force in General Theory is produced by mass, momentum, and stress density of a fluid.

In metric theory of gravitation,a static symmetric perfect fluid solution has tensor fields which is similar to a static round ball of a fluid. The similarity is used for a perfect ideal condition in stars.

Dark fluid is a concept that unites both dark matter and dark energy.

My question is :

(a) Is someway dark fluid related to the fluid solution of General Relativity?

(b) Is the stress-energy tensor has been calculated particularly of a perfect fluid in order to study the details of stellar formations?
