How shocking would the biggest gov't secret be?

IMO, no. Not really. I think that “just knowing it’s possible” is all fine and dandy, but we still have to figure stuff out all of the underlying theories and principles on our own. Which I feel we’re going to do anyway. Eventually.

Remember the premise in “They Live”? Now that kind of government secret (that the self appointed “elite” in our society keep us ignorant of a greater interstellar neighborhood so that they can keep us under control and have all the goodies for themselves) would blow my socks off!

Along these lines, I could easily believe that high-ranking government officials (possibly going right up to the president) have been getting kickbacks to hamstring the anti-drug efforts.

That’s what I was going to say, the other one would be that there is a god and the ruling class have been talking to him on how to run the world (he’s not a nice god though)
