  2. Geocentric model - Wikipedia

    en.wikipedia.org/wiki/Geocentric_model

    The geocentric system was still held for many years afterwards, as at the time the Copernican system did not offer better predictions than the geocentric system, and it posed problems for both natural philosophy and scripture. The Copernican system was no more accurate than Ptolemy's system, because it still used circular orbits.

    While Copernicus's work sparked the "Copernican Revolution", it did not mark its end. In fact, Copernicus's own system had multiple shortcomings that would have to be amended by later astronomers. Copernicus did not only come up with a theory regarding the nature of the Sun in relation to the Earth, but thoroughly worked to debunk some of the ...

    In the early-20th century, the discovery of other galaxies and the development of the Big Bang theory, led to the development of cosmological models of a homogeneous, isotropic Universe, which lacks a distinct spatial central point, which is rather everywhere, [1] for space expands from a shared central point in time, the Big Bang.

    Geocentric celestial spheres; Peter Apian's Cosmographia (Antwerp, 1539) 4th century BCE – Aristotle follows the Plato's Earth-centered universe in which the Earth is stationary and the cosmos (or universe) is finite in extent but infinite in time. He argued for a spherical Earth using lunar eclipses [24] and other observations.

    en.wikipedia.org/wiki/Copernican_principle

    Although the Copernican heliocentric model is often described as "demoting" Earth from its central role it had in the Ptolemaic geocentric model, it was successors to Copernicus, notably the 16th century Giordano Bruno, who adopted this new perspective. The Earth's central position had been interpreted as being in the "lowest and filthiest parts".

    The Tychonic model was a hybrid model that blended the geocentric and heliocentric characteristics, with a still Earth that has the sun and moon surrounding it, and the planets orbiting the Sun. To Brahe, the idea of a revolving and moving Earth was impossible, and the scripture should be always paramount and respected. [ 33 ]

    en.wikipedia.org/wiki/Copernican_heliocentrism

    The Copernican model displaced the geocentric model of Ptolemy that had prevailed for centuries, which had placed Earth at the center of the Universe. Although he had circulated an outline of his own heliocentric theory to colleagues sometime before 1514, he did not decide to publish it until he was urged to do so later by his pupil Rheticus.
