That’s a fair amount of revisionism. First of all, the trial is not the real problem here. The trial could be easily dismissed as a one-off blunder. To understand the real problem, we must have a look at the chronology.Then, as today, the Church took the stance that new ideas were to be looked at slowly and carefully before being adopted. Gallileo was correct (and not particularly original) in his conclusion that the earth orbited the sun. He was blatantly INcorrect in his assertion that the sun was the center of the universe AND was incorrect in his theological assertions that his observations proved that Scripture was man-made and not infallibly inspired by God. It was the hasty conclusion like Gallileo’s that the Church has alwasy been wary of.
Galileo had observational evidence that the geocentrism was wrong back in 1610, and published it in 1613. His evidence was telescopic observation of phases of Venus. He noted that he can observe full Venus, which is impossible under a geocentric system. To understand why, here’s a handy Youtube video of a Ptolemeic Venus: youtube.com/watch?gl=GB&hl=en-GB&v=OlnlbZHP-jk What he saw instead was consistent with the heliocentric system: youtube.com/watch?gl=GB&feature=related&hl=en-GB&v=0Z_v7Tag4fg . In the same year, he observed the moons of Jupiter, and noted that they obviously orbit Jupiter, thus providing counterexample to the commonly held notion that everything in the Universe orbits the Earth. Both observations could be easily repeated. (In fact, today that’s something every backyard astonomer does after getting his first telescope. And looking at Jupiter for the first time yourself is one of these rare moments where you realize that a very simple discovery can trigger a massive paradigm change. But I digress…)
The Inquisition started investigation of Galileo’s claim in 1616, i.e. 3 years after Galileo published the evidence about phases of Venus, and formed a commision of theologians. The investigators did not bother to have a look at Venus themselves, or conduct a simple experiment involving a candle and apples. Unfortunately, both of these things require the intellectual capabilities of a 5-year-old, and these 11 learned men knew better. So they labored hard, and produced a statement which said that this proposition is foolish and absurd in philosophy, and formally heretical since it explicitly contradicts many places the sense of Holy Scripture, according to the literal meaning of the words and according to the common interpretation and understanding of the Holy Fathers and the doctors of theology.. It is clearly evident from this statement that they did not attempt any verification of Galileo’s claims, but instead limited themselves to studying books. Big mistake, but understandable if you consider that these finest minds were trained in scholastic worldview…
And from that point on, it only gets worse. Galileo (following Copernicus) was in error because he assumed circular orbits, so his predictions of planetary motion were way off. But, a German guy named Kepler has figured out in 1621 that the orbits are, in fact, elliptical. (That posed another major problem even for Kepler himself, as departure from perfect, circular orbits meant that the Creator’s work is in fact imperfect). Besides that, he figured out two other laws of planetary motion (for the total of three) and, when he applied these, his planetary predictions were on the mark. So heliocentrism has been pretty much validated by 1630.
That’s another crucial point here; Galileo was charged with breaking the 1616 injuction, which said that it’s OK to entertain the hypothesis of heliocentrism, but stating that heliocentrism is a fact was forbidden. So, in 1632 Galileo publishes his book. The 1633 tribunal ignores 17 years of revolutionary development in astronomy and focuses on a legal matter: whether Galileo’s book teaches heliocentrism, thus violating the 1616 injunction. That’s the Church’s fundamental error here, repeated for the second time. Failure to do due diligence in investigating the matter (to put it charitably), or downright refusal to familiarize with the scientific developments.
As bad as the trial was, the Church still managed to go downhill from there. In 1664, Pope Alexander VII publishes a new edition of the Index of forbidden books – which includes proscriptions of Copernicus, Galileo, Kepler and anything related to teaching heliocentrism as a fact. Never mind another 30 years of scientific progress, the faith of the Church’s officials in the judgement of their predecessors remained unshaken.
In 1687, Issac Newton publishes Philosophiæ Naturalis Principia Mathematica which contains a mathematical formulation of the law of gravity. Application of that law to planetary motion clearly demonstrates that it is the Sun which must sit it in the center of the Solar System, for the simple reason that the Sun is the biggest and the most massive object up there. The Congregation of Index is still unimpressed; books teaching heliocentrism remain forbidden from the Church’s faithful and the declaration of heliocentrism as a formal heresy remains in force. Never mind that the Catholic universities everywhere teach Newton’s laws and heliocentrism as a fact, technically getting the staff excommunicated latae sententiae.
The Church officials finally get a clue in… 1758 and drop the prohibition on heliocentrism. Gee, thanks; it was already irrelevant anyway.
