Grandiloquent is a fancy term for, well, being fancy or pretentious. In fact, you might say grandiloquent is itself a pretty grandiloquent word. The word grandiloquent generally refers to the way a person behaves or speaks.

In astronomy, the geocentric theory of the universe is the idea that the Earth is the center of the universe and other objects go around it. Belief in this system was common in ancient Greece. Two common observations were believed to support the idea that the Earth is in the center of the Universe.

The first big problem with the geocentric model was the retrograde motion of planets like Mars. His model has the planets moving around the Sun in circular orbits. This can explain retrograde motion, but his model doesn’t fit all the planetary position data that well.

The intersection of the two axii is where Earth is located. We are at the center of the universe. In 2005, data from the Sloan Digital Sky Survey showed us that galaxies are arranged in concentric spheres with Earth and the Milky Way galaxy at the center. Centrifugal force keeps the sun from crashing into the Earth.

In Ptolemy’s geocentric model of the universe, the Sun, the Moon, and each planet orbit a stationary Earth. Ptolemy believed that the heavenly bodies’ circular motions were caused by their being attached to unseen revolving solid spheres.

The Ptolemaic system was a geocentric system that postulated that the apparently irregular paths of the Sun, Moon, and planets were actually a combination of several regular circular motions seen in perspective from a stationary Earth.

An Earth-Centered View of the Universe. The Earth was the center of the Universe according to Claudius Ptolemy, whose view of the cosmos persisted for 1400 years until it was overturned — with controversy — by findings from Copernicus, Galileo, and Newton.

The fact that planets travel on elliptical paths is known as Kepler’s First Law. Once he understood that planets traveled in ellipses, he determined that an invisible line connecting the sun to a planet covered an equal amount of area over the same amount of time.

He died in blissful ignorance, as Uranus was only discovered in 1781. Still, his laws remain valid and are key in the study of astronomy. His mistake was to believe irrationally on his rational vision of the cosmos, giving it a finality it (or any other a priori scientific theory) didn’t deserve.

Brahe’s Most Famous Student Brahe was a nobleman, and Kepler was from a family who barely had enough money to eat.

Scientists have just exhumed the body of the 16th century Danish astronomer Tycho Brahe. His remains are to be analysed to check if he was poisoned. However, Kepler had stolen the data which had been bequeathed to Brahe’s heirs, and fled the country after the astronomer’s death.
