cgraves67: Stonehenge is all well and good. I'd like to know the reasons behind Gobekli Tepe, and whether it predated agriculture. I'd also like to find out why Illinois's own ancient empire, Cahokia, collapsed.


As best archaeologists can figure, the decline and fall of most ancient cities and nations is probably attributable to a common cause: too much of a good thing. Ancient Sumeria declined due mainly to soil nutrient depletion. The Mayans, same thing, plus other common effects of too many people in the same place. A number of other ancient Native American settlements of impressive size seem to have suffered the same or very similar fate. And the same for several ancient cities of Africa, and elsewhere in the world.

But nothing like that can happen to us in our enlighened modern civilisation. We're much too smart to let anything like that happen, so no future archaeolists or Farkers will wonder what happened to us.

You Are All Sheep: Of all the things that will happen in the future, including warp drive, time travel is something I don't think is possible, ever.


I think it might depend on what you count as 'time travel'. From what I believe I've made of the few real scientists who at least seem to believe they have some grasp of what's really possible, a *kind* of time travel may be possible, but it's not one we'd likely find desireable or useful. As best I believe I understand it, it's not possible to go forwards in time at all (except by normal acceleration), and it's strictly impossible to go backwards in your own timecone, because laws of causality would make it impossible. Rather, you can move *laterally* through time, jumping from your own timecone to another, and could conceivably travel into the 'past' of a *different* timecone from your own. However, you can never return to any point in the relative 'future' of any timecone you've already visited, only to the relative 'past,' again for reasons of causality. In fact, I think one guy said you can only visit each timeline once, ever, including the one you started in: once you leave, you leave forever.

Time travel 'forward' is achievable. whether it be thru cryogenics, light speed, etc. Going backwards is not possible. No trip to see the dinos.
