Galileo backed Copernicus despite data

Galileo Galilei was right: Earth moves around the Sun, just as Nicolaus Copernicus said it did in 1543. But had Galileo followed the results of his observations to their logical conclusion, he should have backed another system — the Tychonic view that Earth didn’t move, and that everything else circled around it and the Sun, as developed by Danish astronomer Tycho Brahe in the sixteenth century.

**Sounds a lot like the current “global warming, climate change” issue of today.

Here’s a CA article on the Controversy;**

But only partially. I believe he stressed the belief that it moves in a perfect circle.

These were very interesting articles - I had never heard of the Tychonic system before. There was one other thing that Galileo got wrong, however, and that was his belief that the planets moved in circular orbits. At the time, no one had proof that any particular description of the solar system was the right one; Galileo was right about the heliocentric system but couldn’t prove it. His theory, like all of the others, had inexplicable difficulties that required fudging. Circular orbits provided no explanation for the fact that the speed of the planets changes and that they sometimes appear to move backwards. The Church was wrong to have persecuted Galileo but they were right in not accepting an unproven theory as fact - especially given its theological implications.

Galileo would have saved himself a lot of grief if he had had better people skills. He had a caustic personality and always needed to be right.

And he wasn’t always right; he was wrong about the cause of the tides. Ironically, he and the pope were old buddies, and liked to discuss science and philosphy together. Such as the tides. Galileo thought the tides were caused by the oceans sloshing around due to the movement of the earth. The pope didn’t have a theory but thought Galileo should look at other causes besides that. Here, the pope was right.
