Interstellar

introduction

Cooper and TARS are ejected from the tesseract. Cooper is picked up and awakens on a space habitat orbiting Saturn, where he reunites with an elderly Murphy. Using the quantum data sent by Cooper, the younger Murphy had solved the gravitational propulsion theory for Plan A, enabling humanity's mass exodus and survival. Nearing death and with her own family, Murphy urges Cooper to return to Amelia Brand, telling him that "no parent should have to watch their own child die". Cooper and TARS take a spacecraft to rejoin Amelia and CASE on Edmunds' habitable planet.

Driven by regret of having missed being there for his children and motivated by love that 'transcends the dimensions of space and time', Cooper manipulates the second hand of the wristwatch he gave Murphy, using Morse code to transmit the quantum data that TARS collected from inside the event horizon. Back on Earth and further back in time, Murphy finally realizes it was her father from the future trying to communicate with her and assisted by the aberrant ticking of the seconds hand in her watch, deciphers the Morse code.

With insufficient fuel to reach Edmunds' planet, they use a slingshot maneuver so close to Gargantua that time dilation adds another 51 years. In the process, Cooper and TARS jettison themselves to shed weight and propel Endurance using Newton's third law to ensure Endurance reaches Edmunds' planet. Slipping through the event horizon of Gargantua, they eject from their respective craft and find themselves inside a massive tesseract, constructed by future humans inside the singularity. Across different time periods, Cooper can see through the bookcases of Murphy's old room on Earth and weakly interact with its gravity. Cooper realizes he was Murphy's "ghost".

Mann reveals to Cooper that the frozen planet is uninhabitable as he had sent falsified data in order to be rescued; Mann attempts to kill Cooper so that he can take the Endurance to "complete the mission" by going to Edmunds' planet. He then takes a lander and heads for Endurance. Meanwhile, Romilly is killed by a booby trap left by Mann. Brand and Cooper race to the Endurance in another lander. Mann dies during a failed manual docking operation, severely damaging Endurance. After a difficult docking manoeuver, Cooper regains control of the damaged but functional Endurance.

Plan B was always Professor Brand's only option. Murphy accuses Brand and Cooper of knowing that those left on Earth were doomed. Cooper subsequently declares that he will be returning to Earth while Brand and Romilly will remain on Mann's planet for permanent habitation as the planet is believed to be habitable. Cooper goes with Mann to explore and inspect the planet.

Edmunds' planet has slightly better telemetry, while Mann broadcasts positive data. Cooper decides to use their remaining fuel to reach Mann's planet, where they revive him from cryostasis. Meanwhile, Murph, now a scientist working with NASA, transmits a message announcing Professor Brand has died. She has learned that Plan A, which required unattainable data from within a black hole, was never viable.

After finding wreckage from Miller's ship, Brand disobeys Cooper’s order to re-board immediately because of her insistence in checking the wreckage, leading to the death of Doyle by a gigantic wave (caused by the gravitational pull of the black hole). The landers’ engines flood and take some time to clear, delaying their departure further. Due to the proximity of the black hole, time is severely dilated: as a result, 23 years have elapsed for Romilly on Endurance by the time Cooper and Brand return.

Cooper is recruited to pilot the Endurance. The crew includes scientists Dr. Amelia Brand (Professor Brand's daughter), Dr. Romilly, Dr. Doyle, and robots TARS and CASE. Before leaving, Cooper gives a distraught Murphy his wristwatch to compare their relative time for when he returns. After traversing the wormhole, Romilly studies the black hole while Cooper, Doyle, and Brand descend in a landing craft to investigate Miller's planet, an ocean world covered in waist-high water.

Astronauts Miller, Edmunds, and Mann reported positive results. Based on their data, Professor Brand conceived two plans to ensure humanity's survival. Plan A involves developing a gravitational propulsion theory to propel settlements into space, while Plan B involves launching the Endurance spacecraft carrying 5,000 frozen human embryos to settle a habitable planet.

she attributes the anomaly to a ghost. Cooper eventually deduces the patterns were caused by gravity variations and that they represent geographic coordinates in binary code. Cooper follows the coordinates to a secret NASA facility headed by Professor John Brand, Cooper's former supervisor. Professor Brand says gravitational anomalies have happened elsewhere. Forty-eight years earlier, unknown beings positioned a wormhole near Saturn, opening a path to a distant galaxy with twelve potentially habitable worlds located near a black hole named Gargantua. Twelve volunteers traveled through the wormhole to individually survey the planets.

In 2067,crop blights and dust storms threaten humanity's survival. Corn is the last viable crop. The world also regresses into a post-truth society where younger generations are taught false history, including the faking of the Apollo moon missions. Widowed engineer and former NASA pilot Joseph Cooper is now a farmer. Living with him are his father-in-law, Donald; his 15-year-old son, Tom Cooper, and 10-year-old daughter, Murphy "Murph" Cooper. After a dust storm, strange dust patterns inexplicably appear on Murphy's bedroom floor;
