Difference between Cosmological constant problem and Zero-point energy

Cosmological constant problem vs. Zero-point energy

In cosmology, the cosmological constant problem or vacuum catastrophe is the disagreement between the observed values of vacuum energy density (the small value of the cosmological constant) and theoretical large value of zero-point energy suggested by quantum field theory. Zero-point energy (ZPE) or ground state energy is the lowest possible energy that a quantum mechanical system may have.
