Here's why:
* Hubble's observations: Hubble's groundbreaking observations of galaxies and their recession velocities provided strong evidence for the expanding universe, a concept incompatible with a geocentric model.
* Scientific consensus: By the time Hubble was making his observations, the heliocentric model was firmly established in the scientific community. The geocentric model had been disproven centuries earlier by observations and calculations by Copernicus, Galileo, and others.
* No evidence for geocentrism: There is no scientific evidence to support the idea that the Earth is the center of the universe.
It's important to remember that Hubble's primary contributions were in the field of cosmology, not specifically focused on the solar system. However, his understanding of the universe was undoubtedly based on the heliocentric model, which was the accepted scientific understanding of the time.
