Star formation across the cosmos has fallen by roughly 59 per cent in 4.5 billion years, yet its reservoir of neutral atomic hydrogen declined by only about 11 to 26 per cent—a mismatch that rules out rapid loss of atomic gas as the primary cause and shifts the mystery to how galaxies convert that gas into star-forming molecular clouds.
