Johannes Kepler
Nicolas Copernicus did not use a telescope, the use of the telescope to study the solar system was not done until over 50 years later by Galileo.
the ideas would prove all knowledge to be wrong
Because he didn't invent the Telescope so he saw it from his naked eye
The only part of Copernicus's theory that Kepler retained was the idea that the Sun is at the centre of the Solar System.
he did his work to prove his point that he thought were very true
Johannes Kepler
Galelei derived his theory from Copernicus. To Copernicus it was just a theory. Galilei managed to prove it when he invented the telescope and was able to see the moons orbiting Jupiter.
Copernicus created the mathematical theory to prove that the Sun, not the Earth, was the centre of our solar system. Galilei provided the calculations and observations to prove Copernicus' theory.
because he wanted to and he wanted to prove that the sun was in the middle of the universe and not the earth

The astronomical telescope.
Galileo did not prove that Earth was not flat (It had already been agreed that it was round). Galileo invented the telescope and used it to prove that there were objects which did not orbit the Earth, supporting Copernicus' Heliocentric model for the universe. The Earth was known to be round by the ancient Greeks, but I do not who it found out initially (sorry).

No. He was the first in Western society to legitimately propose that the sun was the center, but it took others to prove it. The sun is not the center of the universe, merely the center of our solar system.
