Because there is a belief that the galaxies move away from you once you walk
geocentric theory
They thought it was a explosion in the universe so they sent astronauts into space.
i do believe its FAMILY
Astronomers can watch galaxies that are far away. Since the light takes billions of years to reach us from the farthest known galaxies, they would be watching galaxies in the early Universe. It turns out, from such observations, that the Universe is changing.
Because they thought that planets moved on little circles that moved on bigger circles, and they didnt have modern technology like other astronomers had

The telescope wasn't invented until about 1604, so "early" astronomers had no telescopes.
EARLY astronomers primarily used mathematics; that's why so many "early astronomers" are described as "mathematician and astronomer". Until the invention of the telescope in the early 1600's, there were no astronomical tools beyond the octant.
It may seem odd or even foolish once you understand the structure of the universe, but imagine trying to figure it out without science and today's knowledge. The only things you've seen are the things around you and the stuff in the sky. It would seem natural to believe the Earth is the center of everything and the stuff in the sky surrounds the Earth.
astroneomers were not shunned because of the geocentric model but the heliocentric model (with the sun in the middle of the universe). This was because religious leaders believed that god created the earth as the center of the universe and this idea was believed by nearly everybody.
