Its shown that in the black hole maze , at back of murph s' library he saw cooper in past convincing murph to let him go to space . so he sents the message "STAY" . Then its shown that he goes out of the room at a glance at the fallen book from the shelf. he screems "stay.... idiot stay" then TARS contacts him through 5th dimension gravity connection
But then he found that the singnals are sent by him and TARS , the so called "they" are actually Tars and cooper himself. then he sents the location of NASA throught morse language. How can that happen .its shown that the cooper in the past has gone to space. finding location of NASA was happened before that. before the stay message and all. how can that shown after he gone to space. it doesn't make sense . that sceen was to shown at first and if it shown first. then there is a questian that why did he sent that, if he know its troubble here. and if its shown first then the sceen that he senting that STAY message cant be shown , because it may look contridactry. so Nolan played fare . shown it last to simply confuse , he fooled the audians and there by get continuation of the story.
TARS And Cooper
If TARS and cooper can communicate through the 5th dimensional gravity signal. then why didn't TARS communicated NASA through it. if they can communicate , cooper can also communicate to Amelia. TARS actually sented the complicated location data of them to Murphy. then why didn't she found TARS and Brand even after that she made a space station by the help of it. and there by succed plan A .
The First Hand Shake & Journey From Garguanta To Worm Hole
Then its shown that the library mazes in the black hole has gone and Cooper suddenly reached the worm hole . then he gave the first handshake to Brand in the past . how could that happen ?? the black hole is near garguanta and worm hole is near saturn and how did he reached there from the space.
