The lithium problem

Big Bang nucleosynthesis describes how the first light elements formed. It predicts that the universe should contain roughly three times more lithium-7 than astronomers find in the oldest stars. This gap, known as the lithium problem, has persisted for decades without an accepted solution.

RSI addresses it without new particles or exotic stellar physics. In RSI, element formation is not a purely statistical series of collisions in an empty void. It is a fluid-dynamic event inside the Eternal Consonance. Local field geometry, the density shadows of forming knots, and the resonance of the resulting nuclei all shape what forms.

Lithium-7 has three protons and four neutrons. Its proton count is odd and its pairing is incomplete, so its internal geometry does not settle into the field's rhythm as readily as helium-4 or carbon-12. In the pressurized early field, RSI proposes, the Universal Mechanical Clamp favored more consonant structures and naturally suppressed dissonant ones.

On this view, the observed lithium is not a shortfall from a correct prediction. It is the expected output of a resonant forge. The standard calculation predicts too much lithium, RSI argues, because it treats the early universe as an empty statistical ensemble rather than a pressurized resonant medium that produces what it harmonically supports. RSI must still show that the trough era of the medium's breathing produces the measured amounts of hydrogen, helium, deuterium and lithium.
