If we have the power to turn another planet into Earth, then we have the power to turn Earth back into Earth.

I try to keep this in mind when tied in to a rope 75 feet up in a tree... The history of ideas about our place in the universe has been a long series of let-downs for those who like to believe we are special.

FM signals and those of broadcast television...travel out to space at the speed of light. Any eavesdropping alien civilization will know all about our TV programs (probably a bad thing), will hear all our FM music (probably a good thing), and know nothing of the politics of AM talk-show hosts (probably a safe thing).

What scientists want next is a thorough comparison of what we and exosolar planets and vagabonds look like. Only in this way will we know whether our home life is normal or whether we live in a dysfunctional solar family.

Here's what I'm wondering: if, digitally, you can remove red-eye, smooth over wrinkles, make people look thinner, then why don't we have the technology to make me sing better?

Humans aren't as good as we should be in our capacity to empathize with feelings and thoughts of others, be they humans or other animals on Earth.

We are only intelligent by our own measures
