I absolutely love the fact that Dr. Tyson is shocked that such an advanced question came from such a young child.
It is children like that who are the hope for our future. The ones with great imagination, who constantly wonder about how things work, and dream the dreams which expand out horizons and push out civilization forward.
These are the children who are NOT taught to believe rather than think, and who we desperately need to protect from becoming burned out in high school after years of memorizing facts to prepare for their exit exams that NCLB demands from them before providing them with their diplomas.
Because our education system now seems determined to destroy this kind of "outside the box" thinking in exchange for creating a country filled with cookie cutter versions of what certain politicians believe represents the "best" America has to offer.
I could not disagree more with that opinion.
