Carl Sagan Quotes About Love: 60+ Real Quotes on Cosmic Connection

Not all of Carl Sagan’s most Googled quotes involve astronomy; a researcher of galaxies throughout his career, the Big Blue Man had more to say about other topics. Carl Sagan quotes about love appear in search results since he spoke about connection with the same sincerity that he spoke about the cosmos, and he wasn’t filling his lines with pretty flowery words. His own (true) words about the nature of love, as he expresses it in the book Cosmos, Contact, Pale Blue Dot, and words written by his wife and daughter about the nature of their love.

1. Carl Sagan Quotes About Love and Ann Druyan

His most famous words on love were written for one person: his wife, Ann Druyan.

“For small creatures such as we, the vastness is bearable only through love.” — Contact
“When you’re in love, you want to tell the world.”
“In all our searching, the only thing we’ve found that makes the emptiness bearable is each other.”

Short list. Every line on it is genuine, and every line still gets shared at weddings, funerals, and quiet 2 a.m. moments.
