This exchange is the stuff of scientific and cultural legend. When Neil DeGrasse Tyson accepted Sagan’s invitation and spent a Saturday touring Cornell University labs with the famed astrophysicist, his life was irrevocably changed.
A 17 year old when he met Sagan for the first time at Cornell University, Tyson later described the encounter in this way:
“At the end of the day, he drove me back to the bus station. The snow was falling harder. He wrote his phone number, his home phone number, on a scrap of paper. And he said, “If the bus can’t get through, call me. Spend the night at my home, with my family.”
