The Solar System

Why did Galileo go to jail for publishing evidence supporting the sun centered solar system?

He did not actually go to jail, but his activities were severely restricted by the Roman Church, which then had real power in government and law.

The Catholic Church didn't like his conclusions about the theories of Copernicus. This was mainly based on early texts quoted in the Bible that stated that the Earth was immovable. Galileo was convicted of heresy in 1633 and spent the rest of his life under house arrest.


Galileo promoted the Copernican system with the Sun at the centre. The Vatican said it was OK to promote it as a way of modelling the movements of the planets, but he could not say it was the absolute truth unless there was proof. He continued saying it was the absolute truth and depicted the Pope as an idiot in one of his books, so was put on trial, and when the crunch came he was asked for proof of what he was saying, but he had no proof and he recanted. Proof did not come for another 200 years when the concept of kinetic energy had been invented in the 1800s. The story of the Catholic Church suppressing truth was convenient at the time to Protestant propagandists.


What is Galileo's Diagramma Veritas?

diagram ma Della Verita - the diagram of truth

its an essay by Galileo written for the Illuminati, to tell them about heliocentricity, elliptical orbits, and many other facts considered blasphemous by the Catholic Church. It was written on sedge papyrus, so that any scientist or Illuminatus caught with the Diagramma could simply throw it into water, and Galileo's work would be washed away. There is only one surviving copy, due to the previous method of destruction and Vatican burnings. The only copy is, ironically, kept in the Archives of il Vaticano itself.


Why was Galileo Galilei wanted by The Roman Inquisition?

Galileo Galilei was tried for suspicion of heresy in 1633. The Roman Inquisition believed that Galilei was challenging the Bible and Christianity as a whole by stating that the sun was the center of the universe, not the earth, an idea known as heliocentrism.

The Inquisition clearly pointed out to Galilei that the Bible stated that the earth was at the universe's center and that everything revolved around it, as God had intended. Though this is currently known to be false, it was considered high treason to challenge the Bible and Roman Catholic Christian authority.

Galilei, however, persisted and continued to defend heliocentrism. The Inquisition ruled against him. Galilei was imprisoned and forced to publicly apologize, stating that the earth was in fact the center of the universe as the Bible claimed. His literature were banned and most were burned.

This was presented as a famous case in which science battled religion and it was said that he church attempted to resist scientific discovery and ideas. But the modern model of planetary motion incorporating the heliocentric idea with later scientific discoveries is now accepted as correct.

On October 31, 1992, Pope John Paul II expressed regrets for how the affair between the Inquisition and Galilei was handled and issued a declaration acknowledging errors committed by the Catholic Church. In March of 2008, Vatican City erected a statue of Galilei within the Vatican walls to complete their rehabilitation with him.


Answer: religion and science were never in opposition in this affair, although this was claimed by the newly established protestant churches. The Vatican assured Galileo that he was free to teach the heliocentric theory as a useful model of the solar system, in predicting the positions of planets; but he was forbidden from saying that the Sun is in fact at the centre because it had not been proved sufficiently.

The Vatican said further that if proof could be found that the Sun is after all at the centre, the Church would have to re-examine the scriptures. Galileo's problem was that he had no convincing evidence because Newton's theory of gravitation and laws of motion had not yet been discovered. He persisted in publishing the 'Dialogue of the two world systems' in which the Pope was portrayed as a simpleton. This led to his court appearance and the lack of evidence for the heliocentric theory was exposed.

After Newton's time sufficient proof was found, because the Sun was discovered to be many times more massive than the planets and it was then agreed that the Sun must stay at the centre while the planets orbit round. The Earth's movement round the Sun was demonstrated by Bessel in 1838 when he detected a small amount of parallax in the position of the start 61 Cygni.

The Catholic Church was right to question Galileo because science at that time did not possess sufficient evidence to support the heliocentric theory.


Did Galileo live in Italy all his life?

Galileo Galilei did spend his entire life within present day Italy. Over the course of his life he moved between the Italian cities of Pisa, Padua, Florence, and Rome.

What are Galileo Galilei's contributions to science?

In the 1590's, Galileo invented the thermometer. In 1609, Galileo perfected the astronomical telescope, improving upon the design of Hans Lippershey (which was imprecise and inverted the image). He also promulgated the theory that Earth and other planets in our solar system revolve around the Sun. This was supported by his discovery of moons around Jupiter, and his observations of the phases of the planet Venus (1610). Galileo conducted experiments with pendulums, establishing the relationships between length and period. He also applied these principles to gravity, determining that objects fall at the same speed regardless of their comparative masses. (This was the famous Leaning Tower expirement.)


Was Aristotle a Renaissance scientist?

No, he was a Middle Ages Scientist

Planetary Science
Planet Jupiter

Who invented jupiter?

There is no single person who is credited with the discovery of Jupiter. Jupiter is one of the five planets that can be seen in the night sky without using a telescope or binoculars. The planet Jupiter has been known since ancient times and was observed for thousands of years by the people of many different cultures. Galileo was the first to observe Jupiter with a telescope, as Jupiter can be seen with the naked eye, the ancients probably the ones who discovered it. Jupiter can be seen from planet earth, so it is hard to tell who actually saw it first!

We will never know when Jupiter was discovered. As it can be the third brightest thing in the night sky, it must have been known to the ancients. It's impossible to know. It's always been visible in the sky to the naked eye as long as man is known to have existed. The planet Jupiter is easily visible to the unaided human eye at night. As such it has been known to man since ancient times and therefore there is no attributed discoverer. The discoverer of Jupiter is not known since it visible with the naked eye. The fact that it is a planet and not a star was known in ancient times by the Chinese and Arabic astronomers. They were called 'wanderers' because they did not stay fixed like stars.

It will never be known who discovered Jupiter. It has certainly been known since historical times and it would certainly have been seen by the earliest of humans as they looked up into the skies.


Did Galileo make the first telescope?

No, but he made it three times better.

Where did Galileo Galilei attend school?

In 1574, at the age of 10, Galileo's family sent him to the monastery of Santa Maria di Vallombrosa, near Florence, because his father wanted him to study medicine (a well-paying profession). But Galileo was interested in mathematics. At the age of 17, he entered the University of Pisa to study medicine, as his father wished, but then changed his major from medicine to mathematics and physics.


What country did Nicholas Copernicus come from?



Galileo Galilei what did he do?

He was a scientist who invented the telescope and famous for the Copernicus theory (a theory explaining that the planets rotate around the sun).


Why was Galileo put in jail?

His discoveies were considered to be outrageous and people thought that he was lying. Lots of people back then still believed that gods had power over the sky.


He promoted the theory of Copernicus that the Sun is at the centre of the solar system, with the Earth going round. It predicted the planets' movements quite accurately and Galileo was allowed to teach it as a useful model.

But when he said that theology was wrong and that the Sun actually is at the centre, the Vatican replied that if it could be proved, they would have to reconsider the scriptures, but it had not happened yet. Galileo answered with a book that portrayed the Pope as simple-minded, and after that he was put on trial and had to admit there was no proof.

Protestant PR seized on the episode to discredit the Catholic church by saying the Vatican was attempting to suppress the truth.

After Isaac Newton's theories had been developed later, it was realised that the Sun is 330,000 times more massive than the Earth and the Sun must be at the centre, which is now generally agreed.

Why did church authorities charge Galileo with heresy?

Galileo defended his views of heliocentrism in Dialogue Concerning the Two Chief World Systems, which appeared to attack Pope Urban VIII and thus alienated him and the Jesuits, who had both supported Galileo's theory up until this point. The theory that the Sun is at the centre and the Earth orbits round it was first put forward by Copernicus and then taken up by Galileo, who asserted that it was the truth rather than just a theory, which got him into trouble with the church.

In court Galileo was asked for proof of the heliocentric theory and he could not produce any, and recanted. But he had made an important discovery with the moons of Jupiter, which orbit round Jupiter. Therefore objects had been discovered which do not orbit the Earth. In the centuries after Galileo's death further scientific discoveries were made that support the heliocentric theory.

Finally after Bessel's discovery of stellar parallax in 1838 no-one (including the church authorities) doubted that the Sun is at the centre of a local system known as the solar system, and the Earth revolves round it. This was formally acknowledged by Pope John Paul II in 1993.

The Moon

What did Galileo learn about the moon when using the telescope?

He discovered that the moon had valleys and craters and that it wasn't smooth.


What are the advantages of astronomical telescopes?

They offer extreme magnifications of the Skies overhead, and thereby provide extreme close up views of real objects millions and billions of miles [kilometers = miles *1.6] away.


Who was Hermann Von Helmboltz?

Hermann Ludwig Ferdinand von Helmholtz (August 31, 1821-September 8, 1894) was a German physician and physicist who made significant contributions to several widely varied areas of modern science.

A large German association of research institutions, the Helmholtz Association, is named after him.
