Vatican Observatory Scholar Says Earth May Be Rarer Than Once Believed

Christopher Graney, an adjunct scholar at the Vatican Observatory, suggests that modern astronomy indicates Earth may be far less common than scientists previously thought. Speaking to EWTN News Nightly on October 2, Graney stated that while other Earth-like planets may exist, the universe is not filled with worlds capable of supporting intelligent life.

In his book, A Universe of Earths: Our Planet and Other Worlds, Copernicus to NASA, Graney argues against the historical belief that Earth is an unremarkable place. He noted that 19th-century astronomers often assumed the universe contained many inhabited worlds, such as Father Angelo Secchi, a pioneering Italian Jesuit astronomer, who believed stars distributed life to innumerable beings. Graney contends that current research reveals a universe of diverse worlds rather than countless planets like Earth.
