In the Geocentric Model, there was a notable observation that objects appeared in same locations in the sky on different days, but their positions slightly changed due to their movements. This led to the realization that the Earth is not the only object in the universe.
In contrast, the Heliocentric Model proposed by Copernicus suggested that the sun is at the center, with planets, including Earth, orbiting around it. This model explained observations more accurately, such as the retrograde motion of planets, which the Geocentric Model struggled to account for. The telescope was a crucial tool that helped to support the Heliocentric theory, revealing more about the positions and motions of celestial bodies.
Additionally, advancements in math allowed astronomers to calculate the gravitational influences of these bodies, leading to our understanding of gravity and how it governs the movements of planets in the cosmos.
The discovery of galaxies like Andromeda shows that there is not just a single universe, but many, each with their own elements and structures, further expanding our understanding of the cosmic scale and the radiation emitted by distant stars and galaxies.
In revisiting these models, it's clear that while the Geocentric Model was foundational, the Heliocentric Model provided a more accurate representation of how the universe is organized and its vastness.
