The Impossible Element Hiding in the Sun

The video explores the discovery of elements, focusing on helium, which was first identified in the sun's atmosphere before being found on Earth. It explains how spectroscopy, a technique that analyzes light spectra, was crucial in detecting helium and other elements. The video also discusses the challenges faced in accepting helium's existence due to its rarity and unreactive nature. The role of Dmitri Mendeleev's periodic table and the eventual inclusion of noble gases like helium and argon are highlighted. The video concludes with the impact of quantum mechanics on understanding atomic spectra and the potential of spectroscopy in studying distant galaxies and exoplanet atmospheres.
