Postulating conformal Weyl scaling symmetry for all fundamental fields affects both gravitational and electroweak theory. A conformal Higgs scalar field determines a modified Friedmann cosmic evolution equation. Tachyonic mass parameter $w^2$ becomes a cosmological constant in this equation. An integrated solution fits consensus Hubble expansion data within empirical error. The time derivative of gravitational Ricci scalar $R$ couples scalar and gauge fields. This determines $w^2$ while retaining the Higgs mechanism for gauge boson masses. A simplified calculation obtains dark energy Friedmann weight in order-of-magnitude agreement with its empirical value. The theory predicts variaetion of the Higgs scalar field on a cosmological time scale.
