Astrophysicist Dr. Neil DeGrasse Tyson was asked by a reader of TIME magazine, "What is the most astounding fact you can share with us about the Universe?" This is his answer.
I started watching these videos after learning of the death of Neil Armstrong, and I felt these videos should be shared. Even if they have been posted before, these are inspiring, moving, beautiful videos that get you thinking about the amazing universe we inhabit. RIP Armstrong, you magnificent bastard.
