Spectral lines Challenge Young Earth Creationism
Spectral lines in astronomy provide a powerful tool for confirming the presence of terrestrial elements in distant celestial objects, fundamentally challenging the claims of young earth creationism. This is because the spectral fingerprints of elements are universal, meaning the same elements found on Earth produce the same unique light patterns everywhere in the universe. This provides compelling evidence for a shared cosmic history that is far older than the thousands of years proposed by young earth creationists. The Universal Fingerprints of Elements The foundation of this astronomical evidence lies in a field called spectroscopy. When light from a star or galaxy is passed through a prism or a similar device, it's separated into its constituent colors, forming a spectrum. Rather than being a continuous rainbow, this spectrum is crossed by distinct, dark lines called absorption lines. These lines are created when atoms in a star's atmosphere absorb specific wave...
