Friedmann Equation. The friedmann equations are a set of equations in physical cosmology that govern the expansion of space in homogeneous and isotropic models of the universe within the context of general relativity. It explains the evolution of the universe as a function of time for different type of models.
The equations for negative. Hence it s important to us to derive and learn the friedmann equation. However before jumping to the friedmann equation we should construct a basic understanding of cosmology.
First person to mathematically predict an expanding universe 1922 derived from einstein s general relativity.
The friedmann equation is the heart of these concepts. One version of the einstein equations is the friedmann equation which describes how the expansion rate changes over time and why in a homogeneous and isotropic universe. The first friedmann equation describes how based on what is in the universe its expansion rate will change over time. The equations for negative.
