I think geocentric theory is not right!!! Only heliocentric theory explains why, I need to prove that!!! But how can I prove that?"
Kepler's Laws of Planetary motion
"I think Nicolaus' theory is right, but his evidence is not strong enough, I should help him with that."
Tycho Brahe's Advanced Heliocentric Theory
"I think Copernicus's theory was good, but I think there still needs to have some revisions."
Nicolaus Copernicus is the first person who propose the heliocentric theory; a theory that saying sun is at the middle of the universe in stead of earth. He first proposed this theory during the 15th century. However the idea wasn't being widely accepted by people. Most people said he burned at the stake, but that is rumor. He died peacefully of a stroke and was buried peacefully in an unmarked grave.
Heliocentric Theory; The Trial of Galileo Galilei
I can prove it! I can prove it, my majesty! U cab prove to you that the Heliocentric theory is right!
Johannes Kepler, an astronomer who created the three laws of planetary motion, those three laws indicate on how planet will orbit the sun. This theory was create during 1618. In these three laws, he informs that all planets orbit the sun will be in elliptical orbit; a line joining the Sun and a planet sweeps out equal areas in equal time; and the square of a planet’s orbital period is proportional to the cube of the semi-main axis of its orbit. The third law has been widely used in the modern world.
Rene Descartes' Deductive Reasoning
If... , then...
I will call this deductive reasoning
Tycho Brahe is an astronomer who had strengthened the heliocentric theory. He came up with an idea of combination of geocentric theory and heliocentric theory. In his theory, he informed that not only the planets in the solar system are orbiting around the sun. Despite, the sun itself also orbit those planets in solar system, too.
Newton's Three Laws of Motion & Gravity
What causes this apple to fall on me?
Galileo Galilei had also contributed to the authenticity of the heliocentric theory, he proved it with observing the phase and the planetary motion of the Venus. Galileo had proved that the heliocentric theory is real with using proof of other planets in the solar system; such as Earth, Earth's moon, Jupiter, and Jupiter's moons, etc. Unfortunately, his theory had made him became an infidel during that time, which got him in a trial.
Rene Descartes was a mathematician who contributes a lot to geometry and world mathematics, one of his biggest achievements is deductive reasoning. Deductive reasoning is about using one event to prove another event.
Issac Newton had created the law of universal gravitation, he had inspired by an apple that had fallen on his head. After the apple fall on his head, he starts thinking, "why is everything falling down instead of staying on the air or fly on the air?" Then, he had came out with gravitational pull, he believes that something underneath the Earth is pulling everything down. Also, he had came up with three laws of motion, which indicates explainable motion and analyzing problems.
