But he insisted that he did not do so because he himself believed in heliocentrism, Kelly said.
Rather, he claimed he was simply showing off his debating skills. Galileo was never tortured, however. The pope decreed that the interrogation should stop short with the mere threat of torture. He died in In his later years Galileo insisted on the truth of the geocentric solar system, Kelly said.

Every observable star would have to be larger, utterly dwarfing the sun and every other celestial body. The problem was that no one at the time understood the subtleties of telescopes. Telescopes focus imperfectly. What should be a point of light in a telescope winds up looking like a fuzzy spot. That spot was what astronomers, including Galileo, were measuring. A full understanding of telescopes and the relative motion of the stars would not be achieved until the 19th century. Today, it is understood to be a key factor in weather patterns, and it is called the Coriolis effect, after a 19th-century scientist.
But this action alone could not explain the Mediterranean tides, which occur twice daily. To this, Galileo argued that the tidal periods in different places were determined by local characteristics that reflected the water surge back and forth within the local basin.
Thus, the twice-daily tides were characteristic of the Mediterranean only. When churchmen or a royal woman argued against Galileo, they were not denying science.
They had science on their side. In , however, Galileo was informed by Richard White of England that this claim was in error; tides are twice daily at Lisbon, too. Yet in , Galileo presented it again, with a key change to his argument from He omitted all mention of the Atlantic tides. The science of the day—the observable evidence, the most correct reasoning—was against him and his theory.
And his opponents knew that. Melchoir Inchofer, S. Zaccaria Pasqualigo, also involved in that rejection, noted the issue of tidal periods. Thus when churchmen or a royal woman argued against Galileo, they were not denying science. The Earth may not be the center of the universe, but neither is the sun; it is just one star in a galaxy of stars, which, in turn, is one among a universe of galaxies.
Any Galileo story that ends with a triumphant finality misunderstands the nature of science itself. No one today views the universe as Galileo did.
The Earth may not be the center of the universe, but neither is the sun. Furthermore, such a story misses the very things about Galileo that made him great: his wider vision; the artistic talent that allowed him to see and intuit the truth even if incompletely; his mathematical ability to ask the right questions and suggest ways of searching for answers; his genius for communicating his ideas to a broad and influential audience.
But just as we must recognize that science is neither monolithic nor always right, we also should be wary of treating the other side of this equation, the church, as if it, too, were a single entity speaking with a single voice. Historians debate the root of that injustice. Some blame the personalities involved. Others cite the political and economic pressures involving the Holy See and the wealth of the Medici family, represented by Grand Duchess Christina.
