The Shift from Earth-Centric to Sun-Centric

For centuries humanity was totally convinced that the entire universe literally revolved around

us. It sounds arrogant now, but between ancient philosophers and

the Church, the rule was that Earth stayed put while the sun and stars did all the

moving. It matched what people saw with their eyes, so nobody questioned

it. Then Copernicus came along and completely flipped the script. He proved the sun

is actually the center and we are just orbiting it. This wasn't just a map update; it

was the moment we stopped blindly trusting tradition and started using actual math to understand

reality.
