Next, “The Cosmological Constant Problem.”
Weinberg’s classic review of the catastrophic mismatch between the amount of vacuum energy measured by cosmologists and astronomers, and the predictions made by quantum mechanical theories of particle physics.
Imo this remains one of the most intriguing problem in all of physics. The paper was published about ten years before the discovery of the accelerating Hubble expansion likely driven by a minuscule positive vacuum energy.
