The belief in the universality of flat-earthers is almost as closed-minded as the actual flat-earthers.
The Surya Siddhanta is an incredible testament to the advanced thinking of ancient Indians. In this text, one can find the roots of trigonometry as well as essential mathematical inventions such as standard notation and the decimal system. In addition, the text describes gravity over a millennium before Sir Isaac Newton developed his theory in 1687. It explains sidereal revolutions and how planets move eastward. It accurately calculates the size and position of distant planets, the length of a tropical year, and the amount of time that has passed since creation. Finally, in its discussion of how time passes at different rates under different circumstances, it contains the seeds for relativity.
