If we find life out there, and it's not us, we will deem it not intelligent. But what may be equally as likely is that we find life that's vastly more intelligent than we are. If that's the case, we are putty in their hands.

Perhaps we've never been visited by aliens because they have looked upon Earth and decided there's no sign of intelligent life.

We are part of this universe; we are in this universe, but perhaps more important than both of those facts, is that the universe is in us.

I lose sleep at night wondering whether we are intelligent enough to figure out the universe. I don't know.

Some asteroids have us in their sights. Be nice to sort of go near them and find out what they're made of, possibly tag their ears so they're always broadcasting to us their location. In case one of their trajectories head straight for us, we'll know well in advance to do something about it.

We think scientific literacy flows out of how many science facts can you recite rather than how was your brain wired for thinking. And it's the brain wiring that I'm more interested in rather than the facts that come out of the curriculum or the lesson plan that's been proposed.
