If you could know one mystery, what would it be?

If Einstein was right FTL is not possible. I do not believe any physical structure can exceed the speed of light, no matter what Scotty Spock ,or Kirk may say.

In all the Billions of Star Systems out there it would be foolish to think we are alone. All efforts to communicate with anything out there at the speed of
light (radio waves) after 40-50 years of trying still no one is answering. If we ever communicate with anything other than man it will be a creature already on this planet. IMO

And only a few hundred years ago, man was wishing he could fly.
