Cosmology

The science of cosmology started with the proposal of the Big Bang Theory, which is scientists best guess on how the universe began. This theory was not widely accepted until two scientists working for a telephone company discovered that energy from the Big Bang explosion may still travel through the universe. Previous to this theory astronomers had always believed that the universe was in a steady-state, meaning that it did not change. In this topic, you will investigate cosmology. You will learn the different theories about the universe's past and its future.
