Modern cosmology developed along tandem tracks of theory and observation. In 1916, Albert Einstein published his theory of ^{[4]} At the time, Einstein believed in a ^{[5]} This is because masses distributed throughout the universe gravitationally attract, and move toward each other over time.^{[6]} However, he realized that his equations permitted the introduction of a constant term which could counteract the attractive force of gravity on the cosmic scale. Einstein published his first paper on relativistic cosmology in 1917, in which he added this * cosmological constant* to his field equations in order to force them to model a static universe.

In the 1910s, ^{[12]}^{[13]} However, it is difficult to determine the distance to astronomical objects. One way is to compare the physical size of an object to its ^{[14]}—which was later called the ^{[15]} This fact is now known as

Given the ^{[16]}^{[17]}

For a number of years, support for these theories was evenly divided. However, the observational evidence began to support the idea that the universe evolved from a hot dense state. The discovery of the cosmic microwave background in 1965 lent strong support to the Big Bang model,^{[17]} and since the precise measurements of the cosmic microwave background by the ^{[18]}

An alternative view to extend the Big Bang model, suggesting the universe had no beginning or singularity and the age of the universe is infinite, has been presented.^{[19]}^{[20]}^{[21]}
