Try to correct people to say, "What a beautiful earth rotation" instead of "sunrise". Doing research means believing works written by old dead men who held power. Sometimes, they are proven false. Other times, they were right all along.

In this case, anyone with a cheap telescope can conduct their own experiment. There's just no excuse for believing in geocentrism in 2023. As I mentioned, this is a…

I agree with the geocentristic mindset being a product of limited vision.

What is verifiable? A well written paper on some particles being smashed together has to be taken on some level of faith unless I have the means and methods to reproduce the event. I do not have the means so I just believe it.

If you study the context and development of Greek culture, astronomy, and mathematics, a good case can be made that if it wasn't Eratosthenes, it was another Greek astronomer.

Babylonians got pretty far from what we can tell. We don't really know how far.

Do you have any sources which discuss this? From what I can tell the Babylonians were really good at mapping the night sky and tracking the positions of the planets and when they reached various waypoints. I hadn't heard of them trying to estimate the relative sizes of the various celestial objects.
