We account for one-sixth of the forces of gravity we see in the universe. There is no known objects accounting for most of the effective gravity in the universe. Something is making stuff move that is not anything we have ever touched.Neil deGrasse Tyson
I've known from long ago that the universe was calling me. If you were one of those annoying adults that said, 'Oh, what are you gonna be when you grow up?' I would say, 'Astrophysicist.' And then they'd walk away real quickly.Neil deGrasse Tyson

The chances that your tombstone will read 'Killed by Asteroid' are about the same as they'd be for 'Killed in Airplane Crash.'Neil deGrasse Tyson
Those who see the cosmic perspective as a depressing outlook, they really need to reassess how they think about the world. Because when I look up in the universe, I know I'm small but I'm also big. I'm big because I'm connected to the universe, and the universe is connected to me.Neil deGrasse Tyson
Pretty much every plant and animal alive today is the result of eons of natural cross-breeding.Neil deGrasse Tyson
Every day, I wake up and I say, 'Why... how... did I end up with 1.7 million Twitter followers?' It's freaky to me, every day, but that tells me that there's an appetite out there that had previously been underserved. There's an inner geek in us all, an inner bit of curiosity that people are discovering, and they like it.Neil deGrasse Tyson
