Galileo, who struggled against the Catholic Church to have the theories of Copernicus accepted.
Galileo Galilei was forced to admit publicly by the Catholic Church that the Earth stood motionless at the center of the universe in 1633. This was part of the Inquisition's trial against him for supporting the heliocentric model proposed by Copernicus.
You're thinking of Galileo; however, the fact that he had to deny, or "abjure," was that the Earth orbited the Sun instead of the other way around. People probably did think of the Earth as the center of the universe, however, the concept of "universe" was nothing like what it is today. Even the term used, "cosmos," meant both "universe" and "world."

This statement likely refers to Galileo Galilei, who was famously forced by the Catholic Church to recant his support for heliocentrism (the idea that the Earth revolves around the Sun) in the 17th century. Galileo's support for heliocentrism conflicted with the geocentric view held by the Church at that time.
The statement likely refers to the historical conflict between science and religious doctrine, particularly the heliocentric model proposed by Copernicus, which suggested that the Earth orbits the Sun rather than being the center of the universe. This idea faced significant opposition, culminating in the trial of Galileo Galilei, who was compelled to recant his views on the motion of the Earth. His forced admission highlighted the tension between emerging scientific thought and established beliefs of the time. Ultimately, the truth of heliocentrism was vindicated by subsequent scientific advancements.

The force being tested is gravity, which is pulling the object downward toward the center of the Earth. This force is responsible for the weight of the object and is a fundamental force in the universe.
Yes it can.
You're probably thinking of Ptolemy, though lots of people presumed the Earth was the center of the cosmos, just as they presumed their city was the center of the world. Today we speak of the "Ptolemaic System" (Geocentric) as though he somehow forced this idea on the rest of the world. Actually, the geocentric model was just one way to account for the observed data. Although we would say today that the heliocentric (Sun in the center) model does that better, since there is no actual center to the universe, it's possible to construct a working model using any point as the center for purposes of calculation.
