Description

This lecture covers the importance of the perfect fluid in cosmology, focusing on its coupling to gravity. Starting with the energy momentum tensor of a perfect fluid, the lecture explores the implications in both flat and curved space, culminating in a discussion on the Einstein universe and the concept of static gravity.
