Not everyone is going to like science as a subject.

'As a fraction of your tax dollar today, what is the total cost of all spaceborne telescopes, planetary probes, the rovers on Mars, the International Space Station, the space shuttle, telescopes yet to orbit, and missions yet to fly?' Answer: one-half of one percent of each tax dollar. Half a penny. I'd prefer it were more: perhaps two cents on the dollar. Even during the storied Apollo era, peak NASA spending amounted to little more than four cents on the tax dollar.

We need to look at NASA, not as a handout, but as an investment.

I want people to see that the cosmic perspective is simultaneously honest about the universe we live in and uplifting, when we realize how far we have come and how wonderful is this world of ours.

It turns out that the history of astrophysics is where we perfected time keeping.

So when I think of, what is the meaning of life, to me, that's not an eternal unanswerable question. To me it is in arms reach of me every day.
