What is NASA's mission? Is it to beat the russians? Is it to inspire? - Neil deGrasse Tyson

Science is a cooperative enterprise, spanning the generations. It's the passing of a torch from teacher, to student, to teacher. A community of minds reaching back to antiquity and forward to the stars. (From the first Cosmos: ASO episode, Standing Up in the Milky Way.)

During our brief stay on planet Earth, we owe ourselves and our descendants the opportunity to explore—in part because it's fun to do. But there's a far nobler reason. The day our knowledge of the cosmos ceases to expand, we risk regressing to the childish view that the universe figuratively and literally revolves around us. In that bleak world, arms-bearing, resource-hungry people and nations would be prone to act on their "low contracted prejudices." And that would be the last gasp of human enlightenment—until the rise of a visionary new culture that could once again embrace the cosmic perspective.

What keeps me awake at night: wondering whether human species is just too stupid to figure out the Universe. I just wonder. I lose sleep over that. Because we define ourselves as intelligent— because we made up the test to say that. And we sit alone at the top of the intelligence chart because we invented the exam, and all the other species of life on Earth are not. So who's to say that the first species (us) to be intelligent (us) has just enough intelligence to actually decode everything that's decodable in the Cosmos? [...] Think of the next closest thing to us, the bonobo chimp— 98½% identical DNA, yet you cannot teach them trigonometry, they have no concept of it. So if that's only 1½% difference in our DNA— and so imagine 1½% beyond us, rather than below us, in intelligence. [...] Their toddlers would be talking about things that would completely confound us.
