In 1987, Steven Weinberg wrote a cute little paper entitled “Anthropic Bound on the Cosmological Constant”. I say cute little paper because it feels minor in comparison to, say, electroweak unification theory that won him the Nobel Prize. Weinberg was foundational in establishing the standard model of particle physics, and represented an enormous leap in understanding how this universe works. But his little 1987 paper, though more obscure, may tell us something about how the multiverse works, and can even be thought of as evidence for the existence of an enormous number of other universes.

O’Dowd’s recent videos on multiverse theory have been super enlightening. Weinberg presents a surprisingly convincing argument for a multiverse using anthropic reasoning. Pretty cracked.

The atheists aren’t saying that there was nothing before everything. They’re saying that there was no “before” because time itself started when the universe started.
