So is it like Terminator. Dont try and think too hard about the fact that John Conner's dad is from the future? How did humanity evolve to create the worm hole and lead Cooper through it if not for cooper going through the worm hole. Or in other words the future civilization wouldn't have occurred if cooper didnt go through the worm hole but cooper wouldnt have gone through the wormhole if not for the future civilization. So it's the "John Conner" theory of time travel correct?
