As for how Cooper survives his time inside the Tesseract, and how he intends to reunite with Amelia? Nolan simply reapplies the same theory that has been present the entire film. Given that time moves slower near the gravity pull of the black hole, Cooper’s ejection from the Tesseract is only seconds for him, but over half a century for the rest of humanity. Keep in mind, if the ratio of time on Miller’s planet was 1 hour for every 7 years on Earth, the proportion would be skewed exponentially at the absolute center of the Tesseract singularity. As a result, while it appears to Earthbound humans that TARS and Cooper have been floating out in space for nearly ninety years, they were actually only out there for mere seconds as they perceived it.

No doubt, time-travel die-hards will debate whether the plot results in an unexplained paradox (how did future humans first survive to make a Tesseract – given that there would have been no Tesseract to save them) but Nolan leaves that particular detail up for post-viewing debate.
