In Jonathan Safran Foer's novel "Extremely Loud and Incredibly Close," the narrator explores profound feelings of insignificance in the face of the vastness of the universe and the relentless flow of time. The weight of existence becomes a heavy burden, as the character grapples with the thought that one's presence or absence might not impact the grand scheme of things.

This contemplation on life's meaning highlights the struggles of the character, particularly with loss and the search for purpose. The sentiment reveals a deep existential crisis, prompting readers to reflect on their own roles within the greater context of existence.
