Flat earthers are stupid9/8/2023 ![]() ![]() Luckily, Polaris is one that we can determine the distance to using parallax, because it is also a Cepheid variable star, which allows the distance to be measured to much more distant stars where the parallax method not longer works. ![]() Clueless as to why almost all stars don't appear to change position in the sky from opposite sides of earth's orbit around the sun when the phenomena of parallax says they should, and why we can only use the parallax method for measuring the distance of stars that are closest to the earth.No idea what powers the sun and the stars.No idea what P and S shockwaves detected by seismology equipment tells us about the internal structure of the earth, and the shape and dimensions of the surface of the earth.No idea why the ancient Greeks such as Pythagoras, Aristotle, Eratosthenes and Aristarchus believed the earth was a sphere.No explanation for how the sun and the moon circle the earth, or how the sun migrates from the tropic of Capricorn to the tropic of Cancer and back over the year.No way to determine proper distances, or directions between two point on the earth not sharing the same longitude. ![]()
