It was Copernicus's theory and Galileo had very little evidence for it at the time of his quarrel with the Vatican, as he discovered when they put him on trial and asked for the evidence.
Copernicus's theory was called the Heliocentric Theory. It said that the Earth and planets orbited around the sun, and the Sun was the center of the universe. The previous theory, mainly advocated by the Catholic Church, was called the Geocentric Theory; which stated that the Sun and planets orbited around the Earth, and that the Earth was the center of the Universe.
Geocentricism is the belief that the Earth is the center of the Universe and all other celestial objects revolve around it. (The Geocentric Theory)
Copernicus´s theory that the sun and not the Earth was the centre of the universe was ojected to by the Catholic Church. The church believed that the Earth was special so it had to be the centre and did not believe the evidence as no one could feel the Earth moving. The church went on to persecute many thinkers that supported the sun centred theory.
The original idea (at least, the earliest of which we're aware) that the Earth circled the Sun was proposed by Aristarchus of Samos, a Greek astronomer and mathematician. But the Aristotle's idea that the Sun circled the Earth was more "obviously apparent" and became accepted as fact. The reintroduction of the heliocentric theory by Copernicus, supported by more accurate celestial observations, came almost 1700 years later.
He thought the earth was at the center of the universe and developed the theory of the Crystal spheres. He studied under Plato in Athens, Greece.
The Theory that the earth was not in the center of the universe.
