Claims

C1strongest claim

Compared to the severe 120-digit fine-tuning required for dark energy to be a cosmological constant, our result suggests that the degree of fine-tuning is naturally relaxed by dozens of orders of magnitude.

C2weakest assumption

Assuming a kination epoch in the early Universe to derive the initial-condition constraints.

C3one line summary

Exponential quintessence with an assumed kination epoch relaxes the dark energy fine-tuning problem by dozens of orders of magnitude relative to a cosmological constant.
