How does Cooper in Interstellar end up in a tesseract? [SPOILER]
But how did he end up there specifically? Was it something to do with the wormhole?
Yes, it was actually the beings from the fifth dimension who created the wormhole near Saturn and the tesseract inside Gargantua. They did this to help humanity find a new habitable planet to survive on.
