Dark energy turned out to be not an eternal constant, but a weakening spring. And no fudge factors—everything is dictated by fundamental theory.

Dark energy may be produced by an invisible field that, in the early universe, acted like a stiff spring, but now it gradually weakens. This explains the accelerating expansion without a single arbitrary parameter—all numbers are dictated by fundamental theory.

🎯 Einstein called the cosmological constant his 'greatest blunder'. Now it turns out that perhaps the blunder was thinking it was constant—dark energy behaves like a weakening spring.
