14. Λ and the Search for a Theory of Everything
The cosmological constant problem stands as one of the greatest puzzles in modern physics.
As Nature points out, the value of Λ predicted by quantum theory is vastly larger than what we observe—an enormous discrepancy that blocks efforts to unite quantum mechanics with general relativity.
Solving this mystery is crucial for any future theory of everything, highlighting just how central Einstein’s “blunder” remains in the quest to understand reality’s deepest laws.
