The Evidence for Earth’s Motion: Parallax, Aberration, and Coriolis Effect

This video is part of a comprehensive series initially developed for William Paterson University and CUNY Hunter, aimed at supporting online classes and course materials for introductory astronomy. By engaging with all the videos within this series, you will effectively complete a full undergraduate course in astronomy, equipping yourself with the knowledge and skills necessary to navigate the night sky with confidence, learning all the basics and many advanced topics! Is the Earth actually moving? Despite Newton’s laws of motion and gravitation, the concept of Earth’s movement around the Sun remained unproven due to the elusive phenomenon of stellar parallax. Early attempts by Robert Hooke in 1674 and James Bradley in 1725 didn’t succeed in detecting parallax but led to the discovery of stellar aberration—evidence of Earth’s motion through space. The parallax search continued, and in 1838, Friedrich Wilhelm Bessel successfully measured the parallax of 61 Cygni, providing concrete evidence for Earth’s motion around the Sun. Moreover, the Coriolis effect, predicted by Guglielmini in 1791 through a 29-meter drop experiment inside a tower, demonstrated Earth’s rotation by showing a measurable deflection. This effect was further confirmed through practical applications like naval artillery during the World Wars. These developments confirm not only Earth’s rotation but also its motion through space, proving the heliocentric model. These findings rely on advancements in technology and precise measurements, showcasing the power and importance of scientific inquiry. Image of 61 Cygni: https://archive.stsci.edu/cgi-bin/dss...
