was galileo really the first person to say the earth revolved around the sun?

Answer 1

No ... It was first formulated by the people in India around 200 AD and Copernicus formalized it later in Europe.

Answer 2

No in modern history Copernicus put forth the theory earlier (before Galileo was born) and what Galileo added was evidence that the theory was true.
Early Greeks thought everything revolved around the sun until Ptolemy put forth the earth centric view that stayed put until after Copernicus and Galileo worked on it.
And this is only western civilizations - others new we were solar centric also, but I do not know the whole list

Answer 3

HAM SODA CHICK is mostly correct! The first person to SUGGEST that the Earth and planets orbited the sun was Aristarchus of Samos. This is the first guy to estimate the distance to the moon and sun. I think this is around 65BC

The reason it never caught on as an idea is because PTOLOMY was much more influential at the time. He wwas the guy who said everything went round the earth and he had a working model to back it up.
Little of Arstarchus' work remains. We only know he thought the planets orbited the sun from Ptolomy's work where he simply states that Aristarchus' idea is the preposterous meanderings of a bufoon.

However, that Aristarchus was first to suggest it was not forgotten. Indeed, in Copernicus' first draft of his theory, he clearly states that the idea for his theory first came about from reading that Aristachus had suggested it over 1300 years beforehand.
This statement never made it into the final published edition because the sponsors feared they may be charged with plagarism of someone elses idea, accused that the Copernican theory was not original at all.

Answer 4

In Europe he was the first to say so publicly, though Copernicus had put forward the idea some time before. Galileo was able to prove it with his observations through a telelscope.

Answer 5

As others have said, Aristarchus has a better claim. His idea wasn't rejected because of some sort of personality cult though - it didn't fit the observations. People realised that if the Earth was orbiting the sun there would be parallax effects as the Earth moved in its orbit. No parallax effects were seen so the idea was rejected. The mistake was in underestimating the scale of the universe and hence overestimating the parallax, but it wasn't a popularity contest.

Answer 6

Galileo is certainly the person who the majority of people will claim was the first person to hypothesise a heliocentric model of the solar system, he is certainly the most famous, almost certainly due to the fact that the Catholic Church treated him quite badly claiming his work as heresy.

In fact the person to whom most scientists and historians credit the introduction of the heliocentric model of the solar system is a man from Ancient Greece (around 300 BC). His name was Aristarchus of Samos. Unfortunately for him the more famous and more respected Aristotle and Ptolemy disliked his theory and it fell out of favour until Copernicus revived it two millennia later.

Answer 7

There is evidence that the heliocentric theory was proposed almost 3000 years ago in India. The first well known scientist to claim that the sun was the center was Copernicus around 1514.

Answer 8

Copernicus was the first European to come up with a solid theory as to why this was so. Galileo proved it beyond any reasonable doubt with the help of the newly invented telescope.

Answer 9

Nicolaus Copernicus was the one who formulated the heliocentric model of the solar system. Galileo Galilei later effectively supported this theory.
Galileo improved telescope.
Galileo discovered three of Jupiter's four largest satellites.
He did a lot of studies of the solar system.
He also put forth the basic theories of relativity.

Answer 10

no. people have always debated what shape the world is. though the first recorded person to have said this was at around 100AD, people were probably suggesting it thousands of years before that.
It's never been 'it's flat, or it's round'. someone somewhere along the way probably thought it was triangle shaped, or elephant shaped, or whatever. But no, Galileo wasn't.
