When you're advancing a frontier it stimulates creativity to find solutions.

Jesus Christ rose up from the tomb. Well, he's the son of God, and now he's like God's spirit at this point. Why would a spirit need to move a rock? Why not just pass through the rock? But also, why wait for the guards to go to sleep?

We should not be ashamed of not having answers to all questions yet... I'm perfectly happy staring somebody in the face saying, 'I don't know yet, and we've got top people working on it.'

NASA was invented as a response to Cold War steps. There are those who presumed that we went to the moon because we're explorers. We went to the moon because we were at war with the Soviet Union. And so when it became clear that they (Soviet Union) were not going to the moon, we're done with the moon.

The solar system should be viewed as our backyard, not as some sequence of destinations that we do one at a time.
