If the purpose of the universe was to create humans then the cosmos was embarrassingly inefficient about it.
Neil deGrasse TysonIt'd be a shame to talk about the universe and not show some images of it, because we have some of the more stunning representations of our field relative to any of the sciences. But I don't use the imagery as a substitute for the insights and wisdom I can convey so that when you leave you say to yourself, "Wow, I'm a little more deeply connected to the universe, and I want to learn more."

Neil deGrasse TysonI was raised Catholic. But if someone says I was raised in some religion, that's insufficient information to actually know what was going on. The real question is Was the religion in the household? The answer is no. Important decisions in the household were executed rationally and secularly. So as a result, the foundations of my reasoning derive not from religion but from the rational analysis of circumstances.
Neil deGrasse TysonIn astrophysics, we care about how matter, motion and energy manifest in objects and phenomenon in the universe. Stars are born. They live out their lives. They die. Some of the ones that die explode. Our sun will not be one of those, but it will die. And it'll take Earth with us. So we make sure we have other destinations in mind when that happens. And I've got it on my calendar.
