Ancient Astronomical Sites and Earth's Axial Precession

This chapter explores the use of ancient astronomical sites like Stonehenge for tracking celestial events such as solstices and equinoxes, discussing the adjustments needed over millennia due to Earth's axial precession. The conversation delves into the changing night sky, the use of planetarium apps like Stellarium, and the potential for software to calculate celestial positions over long periods. Additionally, it touches on the importance of accounting for Earth's precession in GPS satellites and discusses creating a searchable index for Q&A show content using platforms like YouTube.
