This view fell apart thanks to the Danish astronomer Tycho Brahe Tycho, usually called by his first name, led an unusual life in many respects. He was born into the upper crust of Danish nobility. Attending a dance at a professor's house at the University of Rostack, Germany, he fell into an argument with another aristocrat, Manderup Parsbjerg.
They fought, and Tycho lost his nose. For the rest of his life, he wore a metal replacement, usually said to be made from silver. According to legend, he died when good manners forced him to remain at a banquet table, even though he desperately needed to urinate.
After several hours of this torture, his bladder burst. Investigations proved that it was indeed a pee related death, and not one of mercury poisoning, which was rumored to have been the case after mercury was claimed to have been found in the remains of Brahe when his grave was examined on the th anniversary of his death.
New, more detailed analysis though shows that it was indeed a ruptured bladder that led to the demise of on of the greatest minds of the 16th century. Almost thirty years before his unusual demise, Tycho had shocked Europe.
In November ofhe was walking home from his uncle's chemistry laboratory and noticed a new star, shining brightly in the constellation Casseopeia. We now know that this was a supernova, a massive star that reached the end of its fuel supply and exploded. Aristotle's astronomy said that nothing in the heavens really changed; all events that looked otherwise comets, falling stars and such were really just like clouds or storms, weather happening in the Earth's air.
Tycho showed that his new star was too far away for that to be true. The next year, he published a book, De Stella Nova, which reported his observations. Most scientific discussion at the time went on in Latin, which let professors and thinkers from different countries communicate in a common language.

This was beneficial, although it did exclude most people from the scientific process. Anyone who couldn't speak Latin was basically shut out from scientific discoveries. He convinced himself that, given the uncertainties of observation at the time, this picture might be the right one. However, that was before Tycho's results were used. Kepler realized that Tycho's work could settle the question one way or the other, so he went to work with Tycho in Tycho died the next year, Kepler stole the data, and worked with it for nine years.
He reluctantly concluded that his geometric scheme was wrong. In its place, he found his three laws of planetary motion: I The planets move in elliptical orbits with the sun at a focus. II In their orbits around the sun, the planets sweep out equal areas in equal times. III The squares of the times to complete one orbit are proportional to the cubes of the average distances from the sun.
These are the laws that Newton was able to use to establish universal gravitation. Kepler was the first to state clearly that the way to understand the motion of the planets was in terms of some kind of force from the sun.

However, in contrast to Galileo, Kepler thought that a continuous force was necessary to maintain motion, so he visualized the force from the sun like a rotating spoke pushing the planet around its orbit. On the other hand, Kepler did get right that the tides were caused by the Moon's gravity. Galileo mocked him for this suggestion.
