Universe 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. 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 first friedmann equation describes how based on what is in the universe its expansion rate will change over time. 4 2 friedmann equations we can now build our universe by taking for each point in time a robertson walker rw space.

The first friedmann equation describes how based on what is in the universe its expansion rate will change over time. If you want to know where the universe came from and where it s headed all. 2 3 friedmann equations let us consider the dynamics of the frw universe that determines time evolution fo the scale factor a t 2 2. 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.
