95, 96 percent of all that drives the universe has no known origin.

Robots are important also. If I don my pure-scientist hat, I would say just send robots; I'll stay down here and get the data. But nobody's ever given a parade for a robot. Nobody's ever named a high school after a robot. So when I don my public-educator hat, I have to recognize the elements of exploration that excite people. It's not only the discoveries and the beautiful photos that come down from the heavens; it's the vicarious participation in discovery itself.

That is a cosmic perspective, that's correct. And in tandem with that, you will never find people who truly grasp the cosmic perspective such as the entire community of astrophysicists leading nations into battle. No, that doesn't happen. When you have a cosmic perspective, there's this little speck called Earth and you say you're going to do what? You're on this side of a line in the sand and you want to kill people for what?

It’s short-sighted to think ads won’t one day end up wherever humans are - even the moon.

New generations of humans inherit the acquired discoveries of generations past, allowing cosmic insight to accumulate without limit. Each discovery of science therefore adds a rung to a ladder of knowledge whose end is not in sight because we are building the ladder as we go along. As far as I can tell, as we assemble and ascend this ladder, we will forever uncover the secrets of the universe - one by one.

Speaking as just simply an American who cares about the economic health of our country, I see one of the surest ways to bring wealth and prosperity to the country is to innovate in science and technology.

A television advertisement must illustrate the scientific method to substantiate any claim.... That is why stains are lifted, ring-around-the-collar is removed, paper towels become soaked, excess stomach acid is absorbed, and headaches go away-all during the commercial.
