I said the same thing about the electricity being on in an abandoned former World Dynamics building. What I don't get is this point: How do the watchers go back in time from 2609 to the past, change the events of the original time line , become the masters of the world, and this doesn't effect the very future they came from? Wouldn't that cause them to change their very existence in the future?
I mean every time travel movie I've ever seen says: if you change one thing in the past, say step on a butterfly in the prehistoric time period , could change the future or present. There was a time travel movie just like that a few years back where they time traveled for pleasure cruises to the prehistoric time and someone stepped on a butterfly and when they went back to the present, they took back the bacteria & diseases of the past to the future and it changed every thing , Even the very existence of man himself.
