Existence & Metaphysics
Is the universe fine-tuned for life, and if so why?
UNKNOWNimportance 80/100 · Unknown
Several constants appear to lie in narrow ranges compatible with complexity and life. Is this significant?
Current explanations
Explanations: multiverse plus observer selection; deeper laws fixing the constants; design; or overstated tuning. The premise itself is debated.
Research progress
The cosmological constant's smallness is the sharpest example; whether "tuning" is real or an artifact of our ignorance of the underlying theory is unsettled.
