Summary
Disheartened by the cancelation of the Superconducting Super Collider, Weinberg turns his attention to the cosmological constant. It must behave like a vacuum energy density, and can be adjusted to cancel the energy in fluctuating fields. Today the effective vacuum energy density, including the cosmological constant, has come to be called “dark energy.”
