https://en.wikipedia.org/wiki/Cosmological_constant_problem
Some supersymmetric theories require a cosmological constant that is exactly zero, which further complicates things.
This is the cosmological constant problem, the worst problem of fine-tuning in physics: there is no known natural way
to derive the tiny cosmological constant used in cosmology from particle physics.
