# Einstein DeSitter Model Cosmic Scale Factor Calculator

In cosmology, the increase of distance in the space expressed in terms of time function is called as cosmic scale factor also known as the Friedmann Robertson Walker Scale Factor. Einstein Theory of relativity was remodelled by desitter in which the universe is considered as flat uncaring about the matters. This calculator is used to find the cosmic scale factor at time.

#### Formula:

R(t) = R_{o} * (t / t_{o})^{2/3}
**Where,**
R(t) = Cosmic Scale Factor At Time
R_{o} = Cosmic Scale Factor
t = Time
t_{o} = Time At Present Epoch
Alexander Friedmann was a cosmologist who gave solutions to the einstein's equations and explained the expanding universe. Friedmann Robertson Walker metric is used to describe the expanding universe.
