We propose a mechanism to make this smoothness natural by weakening the strength of gravity at early times, and therefore altering which initial conditions have low entropy.Previous article in issueNext article in issueKeywordsArrow of timeInitial conditionsWeak gravitySmoothnessRecommended articlesCited by (0)Published by Elsevier B.V.
