What on flat Earth...?
I chat to Mark Sargent about the idea that the earth is flat. Mark is the creator of the online youtube videos called 'Flat Earth Clues'.
The idea of a spherical Earth appeared in Greek philosophy with Pythagoras (6th century BC), although most pre-Socratics (6th – 5th century BC) retained the flat Earth model. Aristotle provided evidence for the spherical shape of the Earth on empirical grounds by around 330 BC. Knowledge of the spherical Earth gradually began to spread beyond the Hellenistic world from then on. Nicolaus Copernicus was a Renaissance- and Reformation-era mathematician and astronomer who formulated a model of the universe that placed the Sun rather than the Earth at the center of the universe. Not everyone agreed with him. It is considered by some, rather egotistical to think the Earth is something special. Nevertheless, even Stephen Hawkins agreed the evidence appears to point to the Earth being at the center. Being humble he preferred to shift the focus onto an infinite universe where the Earth is somewhat insignificant. As a leading voice in the
scientific world, his ideas have become central to our modern way of seeing ourselves.
