It isn’t crazy because it is fact that earth isn’t the center. Technology and knowledge has brought us across great voids that we thought weren’t possible to attempt. We flew to the moon in 1969, but now we have the power to fly to Mars.
This spacecraft was named after Galileo Galileo, the first modern astronomer. In the 1970’s a few other spacecraft’s, such as Voyager 1 and 2 and Pioneer 10 and 11, scouted Jupiter but they were unable to stay for an extended period of time and the amount of information they brought back to Earth was limited. Scientist wanted a spacecraft that could stick around for an extended period of time and gather more detailed information about Jupiter’s environment thus the idea of Galileo was formed. On October 18, 1986 the Space shuttle Atlantis, carrying the Galileo, was launched. Shannon Lucid was the Astronaut that performed the maneuvers that started this spacecraft on its long journey.
He constructed a military compass, an instrument for measuring the expansion of liquids, and one of the early telescopes with which he discovered Jupiter's satellites, irregularities on the surface of the moon, star clusters in the milky way and spots on the surface of the sun. He was initially skeptical of Copernicus' theory however his observations and experiments affirmed his diagram of the universe. Critics attacked Galilei's findings. They said that his "discoveries" were ridiculous to believe and that it was only is imagination or dreams. Galilei wrote a letter to Dowager Grand Duchess trying to reconcile his astronomical observations with the Bible.
Galileo studied Saturn, and noted its irregular ovular shape, but was unable to realise that it was caused by its rings due to his updated telescope being used to its magnification extent. He then found four large objects in space, which he noted were not stars, and were, in fact orbiting the planet Jupiter, and determined the time it took for one to orbit the planet. He also determined the speed to the rotation of the sun. He displayed proof that the Copernican theory was correct, and defended it. He wrote and published several books that lead to conflicts between him and the Roman Catholic
By definition from a Merriam- Webster Dictionary a planet is “any of the large bodies that revolve around the sun in the solar system which have a similar body to them”. This is not a very specific explanation and makes it hard to fully grasp what it means; at this you could easily say that in fact Pluto a planet. However if you look at a scientific encyclopedia the definition is much different and more specific. The Access Science Encyclopedia says a planet is “A) a celestial body that is in orbit around the sun B) has sufficient mass for its self-gravity to overcome rigid body forces so that it can assume a hydrostatic equilibrium shape C) clears the neighborhood around its orbit”. This explanation is much different and clearer about what qualifies as a planet.
Using his own current knowledge and applying Euclid's geometry to the universe's model he created the Ptolemaic system. In the Ptolemaic system, the model had the planets rotating around the Earth which is known as a different. Technically, in the model, the planets weren't revolving around an Earth than was centered, but more of an Earth that was off-centered, which is known as eccentric. To solve the current problem of why the planets speed up and slow down, Ptolemy insisted that the planets do not travel at a set rate, but more of a rate that changes at will. He then brought up the point that the planets do travel at an set rate, but only at the equant.
To the modern reader, Aristotle's views on astronomy, as presented in Metaphysics, Physics, De Caelo (On the Heavens) and Simplicius' Commentary, will most likely seem very bizarre, as they are based more on a priori philosophical speculation than empirical observation. Although Aristotle acknowledged the importance of "scientific" astronomy - the study of the positions, distances and motions of the stars - he nevertheless treated astronomy in the abstract, linking it to his overall philosophical world picture. As a result, the modern distinction between physics and metaphysics is not present in Aristotle, and in order to fully appreciate him we must try to abandon this pre-conception. Aristotle argued that the universe is spherical and finite. Spherical, because that is the most perfect shape; finite, because it has a center, viz.
Later, Newton took to answer. Kepler also came transversely the paths of planets; their path was elliptical, not circular. Planets move in ellipses with the sun at one focus and Prior to this in 1602, Kepler found from trying to figure out the position of the Earth in its orbit that as it sweeps out an area defined by the Sun and the orbital path of the Earth that the radius vector labels equal areas in equal times. This idea turn around to be very popular in the Scientific Revolution, as it stimulated much inquiring. Kepler created the three laws of planetary motion.
Galileo invented the telescope and began studying the heavens above and noticed that changes within the stars and planets. He noticed that the “stars” that surrounded Jupiter moved. He came to the conclusion through rational thinking, that the Copernicus’ heliocentric theory was correct. Copernicus was a scientist and philosopher whose theory proposed that the sun was stationary and the heavens orbit around the sun.

With Galileo’s telescope, however, he was able to show that the sun rather than the earth was the center of the universe.

This is exemplified in the book when the servants and priests refuse to be paid twice for their civil duties. These basic ideas are carried on into the nineteenth century and the period of the enlightenment.
