Below is a summary of three historical scientific theories that model and explain our Solar System.
The geocentric solar system places the Earth at the center of the Universe with all other heavenly bodies orbiting the Earth.
The Heliocentric solar system places the Sun at the center of the Solar System with all planets orbiting the Earth.
The Big Bang theory suggests the Universe was created with a single cosmic explosion. The Universe continues to expand at a n increasing rate as a result of this explosion.
Which action could prove the heliocentric model over the geocentric model?
