It used to be, it is accepted scientific wisdom the Earth is flat, and this heretic named Galileo was branded a denier.

I wound up getting offered a job at the NASA Jet Propulsion Laboratory where I invented a power supply mechanism for the Galileo space craft which was in orbit around Jupiter until 2003.

Galileo was no idiot. Only an idiot could believe that science requires martyrdom - that may be necessary in religion, but in time a scientific result will establish itself.

I was born on January 8, 1942, exactly three hundred years after the death of Galileo. I estimate, however, that about two hundred thousand other babies were also born that day. I don't know whether any of them was later interested in astronomy.

If Galileo had said in verse that the world moved, the inquisition might have let him alone.

So this is where all the vapid talk about the 'soul' of the universe is actually headed. Once the hard-won principles of reason and science have been discredited, the world will not pass into the hands of credulous herbivores who keep crystals by their sides and swoon over the poems of Khalil Gibran. The 'vacuum' will be invaded instead by determined fundamentalists of every stripe who already know the truth by means of revelation and who actually seek real and serious power in the here and now. One thinks of the painstaking, cloud-dispelling labor of British scientists from Isaac Newton to Joseph Priestley to Charles Darwin to Ernest Rutherford to Alan Turing and Francis Crick, much of it built upon the shoulders of Galileo and Copernicus, only to see it casually slandered by a moral and intellectual weakling from the usurping House of Hanover. An awful embarrassment awaits the British if they do not declare for a republic based on verifiable laws and principles, both political and scientific.

He caught a glimpse of that extraordinary faculty in man, that strange, altruistic, rare, and obstinate decency which will make writers or scientists maintain their truths at the risk of death. Eppur si muove, Galileo was to say; it moves all the same. They were to be in a position to burn him if he would go on with it, with his preposterous nonsense about the earth moving round the sun, but he was to continue with the sublime assertion because there was something which he valued more than himself. The Truth. To recognize and to acknowledge What Is. That was the thing which man could do, which his English could do, his beloved, his sleeping, his now defenceless English. They might be stupid, ferocious, unpolitical, almost hopeless. But here and there, oh so seldome, oh so rare, oh so glorious, there were those all the same who would face the rack, the executioner, and even utter extinction, in the cause of something greater than themselves. Truth, that strange thing, the jest of Pilate's. Many stupid young men had thought they were dying for it, and many would continue to die for it, perhaps for a thousand years. They did not have to be right about their truth, as Galileo was to be. It was enough that they, the few and martyred, should establish a greatness, a thing above the sum of all they ignorantly had.

If the people of Europe had known as much of astronomy and geology when the bible was introduced among them, as they do now, there never could have been one believer in the doctrine of Inspirational. If the writers of the various parts of the bible had known as much about the sciences as is now known by every intelligent man, the book never could have been written. It was produced by ignorance, and has been believed and defended by its author. It has lost power in the proportion that man has gained knowledge. A few years ago, this book was appealed to in the settlement of all scientific questions; but now, even the clergy confess that in such matters, it has ceased to speak with the voice of authority. For the establishment of facts, the word of man is now considered far better than the word of God. In the world of science, Jehovah was superseded by Copernicus, Galileo, and Kepler. All that God told Moses, admitting the entire account to be true, is dust and ashes compared to the discoveries of Descartes, Laplace, and Humboldt. In matters of fact, the bible has ceased to be regarded as a standard. Science has succeeded in breaking the chains of theology. A few years ago, Science endeavored to show that it was not inconsistent with the bible. The tables have been turned, and now, Religion is endeavoring to prove that the bible is not inconsistent with Science. The standard has been changed.

We owe a huge debt to Galileo for emancipating us all from the stupid belief in an Earth-centered or man-centered (let alone God-centered) system. He quite literally taught us our place and allowed us to go on to make extraordinary advances in knowledge.

Galileo was no idiot. Only an idiot could believe that science requires martyrdom - that may be necessary in religion but in time a scientific result will establish itself.
