I was a Greek astronomer who believed in the Earth-centered model of the universe (Geocentric). This means I thought the Earth was the center of the universe! Boy was I wrong!
I was an Egyptian astronomer who believed in the Earth-centered model of the universe (Geocentric). This means I thought the Earth was the center of the universe! I was wrong!
I was a Polish astronomer who challenged the Geocentric model of the universe. I introduced the Sun- centered model of the universe (Heliocentric). I believed the Sun was the center of the universe.
I was an Italian astronomer who believed the Sun-centered model of the universe (Heliocentric). I was even put in jail for a long time because of my belief!
