I'd like - inviting aliens and have them observe what we do because so much of what we do that we take for granted will just be weird or extraordinary or just plain dumb when observed by an alien from another civilization.

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).

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?

Newton, Einstein, and every other great scientist in history...They all made mistakes. Of course they did. They're human! Science is a way to keep from fooling ourselves and each other.

Today, scientists sound the alarm on other environmental dangers. Vested interests still hire their own scientists to confuse the issue. But in the end, nature, will not be fooled.

Aliens might be surprised to learn that in a cosmos with limitless starlight, humans kill for energy sources buried in the sand

I never got into 'Star Wars.' Maybe because they made no attempt to portray real physics. At all.
