But Einstein realized that Newton had left something out of the story, because even Newton had written that although he understood how to calculate the effect of gravity, he'd been unable to figure out how it really works.
Ali Einstein je shvatio da je Newton izostavio nešto iz cijele priče, jer je čak i Newton napisao da iako je shvatio kako izračunati utjecaj gravitacije, nije uspio shvatiti kako ona ustvari funkcionira.
