The Cosmological Revolution


The Cosmological Revolution is the debate regarding the structure of the universe. In the Middle Ages it was thought that the Earth was the centre of the universe, and all the other planets (including the sun) went around the earth. The reason that this was believed was because in the Middle Ages, religion was the predominate authority, and it believed that because God created the earth and it contains humanity, it is the most important part of the universe.

However, science began to challenge the Church towards the end of Middle Ages by providing evidence that the earth actually went around the sun.

For example:

  • 1. If science was correct then humanity would not be the centre of the universe, and this means that God did not intend for humanity to be the most important.
  • 2. Science was now free to challenge religion.
  • 3. Science now had the answers and religion would be used to fill in the gaps.

4. God now becomes unnecessary to run the universe.

Nicholas Copernicus (1473 – 1543):Copernicus

Originally employed by the Church, Copernicus was creating a calendar when his observations noted that the sun was the centre of the universe, with the moon revolving around the earth.

It is argued that Copernicus started the Cosmological Revolution with this discovery as he supposedly provided others with the starting point that they could use to develop his theories.

Galileo Galilei (1564 – 1642):Gallileo

Galileo used a telescope to observe sunspots and thought that this proved that the universe was ever – changing and developing in a natural manner.

He thought that by proving the universe was continually changing, then it cannot have been caused to be this way by God.

Therefore, God could not exist.
