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.
Johannes Kepler
Copernicus proved to mankind that the sun was the center of the universe, not the Earth. We know now that he was mostly correct. The sun is the center of the solar system.
In physics, theories are not mathematically proved but instead they are compared with physical observations to see if they are correct. Copernicus's theory was not just an idea that the Sun is at the centre, but also a detailed mathematical system of circle and epicycles that provided a model of the planets' orbits. At the time of Copernicus and for a time afterwards, his theory was used to predict the planets' positions, and when the predictions were found to be 'correct', the theory was considered 'proved' . But later Tycho Brahe developed more accurate measurement techniques, and using those he discovered small errors in the predicted positions of the planets. That led to Kepler's work and the discovery of elliptical orbits.
the ideas would prove all knowledge to be wrong

The astronomical telescope.
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.
Galileo's invention of the telescope helped him observe the phases of Venus, the moons of Jupiter, and sunspots, which provided evidence for the heliocentric model proposed by Copernicus. These observations challenged the geocentric view of the universe and supported the idea that the Earth revolves around the Sun.
Copernicus is the first in modern times, but he may have been basing his theory on the work of an earlier Greek Natural Philosopher. Galileo used a telescope and mathematics to prove Copernicus' hypothesis.
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).
Galileo Galilei constructed telescopes to conduct his observations. He also disproved the Ptolemaic model.
no
he did his work to prove his point that he thought were very true
Johannes Kepler
An experiment can prove they are wrong or right ...:)
It was Galileo.
