Cosmology

the puzzle of why the universe's density is so close to the critical value, which requires extreme fine-tuning of early conditions without inflation.

In cosmology, flatness problem refers to the puzzle of why the universe's density is so close to the critical value, which requires extreme fine-tuning of early conditions without inflation. This meaning comes from Guth (1981) in Physical Review D.[1]
