The Enigma of Lithium Destruction in the Universe.

Scientists are puzzled by the rarity of lithium in the Universe, as the standard model of the Big Bang overpredicts its abundance. Possible solutions include missing knowledge of nuclear physics, unknown processes inside stars, or entirely new physics. Some theories suggest that dark matter or changing fundamental constants may have affected the production of elements in the early Universe. However, the odd rarity of lithium remains a mystery.
