This is MY theory, I think what Stan meant when he said 'We finally have it" is WE referring to his Twin brother that plenty of you have been talking about. I mean MAYBE his twin brother was the one who wrote all those journals and the machine at the end is some sort of time traveling machine that stan will go into to stop whatever caused his brother to disappear
