On his deathbed, Professor Brand confesses to Murph that he lied about his Plan A's prospects – that he failed to “reconcile relativity to quantum mechanics” and his gravity project needs much more data. She takes on the project herself and beams out the bad news to space, where Coop and Amelia receive it.
Mann is an example of humanity's selfish nature – his surname is a not-particularly-subtle bit of signposting – as he deliberately manipulates his data to pretend that his ammonia-filled planet is habitable. He sabotages Coop's crew purely to escape from the planet and make it back to Earth.
Professor Brand considered Plan A to be impossible because in order to solve his gravity equation, he would need unobtainable data from the Singularity of a black hole. Professor Brand went to great efforts to conceal this fact from everybody, including his daughter Amelia and Murph.
Mann, knowing his planet could never support human life, in secret, attempts to murder Cooper, seeing his death as necessary to the completion of the mission, as Mann did not want to let Cooper leave for Earth with the Endurance, since he now needed it to get to Edmund's planet.
Interstellar (2014) | The truth about Professor Brand | The Monstrous lie
What was Dr. Brand's secret?
On his deathbed, Professor Brand confesses to Murph that he lied about his Plan A's prospects – that he failed to “reconcile relativity to quantum mechanics” and his gravity project needs much more data. She takes on the project herself and beams out the bad news to space, where Coop and Amelia receive it.
TARS relays the quantum data to Cooper in Morse code. Cooper in turn relays the quantum data to Murph, in Morse code, through the hands of a wrist watch. Murph somehow knows it's her father relaying quantum data to her through the watch.
Through Dr. Mann says, “I'm here for you,” while Cooper dies, Mann can't tolerate the suffering and turns off the speaker in his helmet. At this point, the film cuts to Murph turning her jeep into the family cornfield, where she will set fire to the corn in order to force Tom to leave.
Mann's last words are, 'Brand, I don't know what Cooper's told you, but I'm taking control of the Endurance, then we'll talk about continuing the mission. This is not my survival, or Cooper's - this is mankind's- '.
Earth is a rocky planet orbiting a G-type main sequence star known as the Sun. The planet is the third in order from its star, home to the human species and assorted varieties of flora and fauna. In the middle of the 21st century, the planet suffered the Blight which threatened to destroy all lifeforms on the planet.
It took the spaceship 18 months to travel to the wormhole, then 23 years passed from exploring planet Miller. Murph said (cried) in the video to his dad that she is finally the same age as him when he left. Which tells us that she and her dad are both 35 years old toward the end of the movie.
Cooper traveled for 2 years to the wormhole and subsequently lost 23 years in gravitational time dilation on Miller's planet. When he returns to the Endurance he receives Murph's message that she is now the same age as Cooper when he departed.
Later, after Cooper allows himself to fall into Gargantua in order to gather the data necessary for Murphy to solve Dr. Brand's equation, he enters the Tesseract, where he realizes that unknown beings who created the wormhole are in fact humans from the distant future.
The goodbye scene between Cooper and young Murph (early on in the movie when he decides to take on the mission) is emotionally excruciating. She begs him to stay but then refuses to speak to him when it is revealed he doesn't know when he will return.
They awaken Mann from cryostasis, and he fills them with the hope that the planet he discovered could support human life. However, he privately reveals to Cooper that this is a lie. He falsified the data so that NASA would send a crew to rescue him.
Who really was the ghost sending Murph messages in Interstellar?
It's only when she returns to the room as an adult however that she realises the ghost is actually her father - the big clue being when Cooper wrote "STAY" in morse by knocking books off the wall while his past self was leaving for the mission, which Murph wrote down as a child and rediscovers as an adult.
He ended up in the hospital bed because he went unconscious when the Tesseract was closing, and the 5th Dimensional beings transported him out of the black hole and assisted him through the Saturn wormhole. He was then found by rangers from cooper-station, and was taken into medical care.
How long did Dr Mann go without human contact in Interstellar?
Mann was marooned on this planet for 35 years, as evidenced by the 23-year time dilation on Miller, the two-year trip to Saturn and the launch of the Lazarus missions which predated Endurance's launch by ten years.
Who are the 5th dimensional beings in Interstellar?
The fifth-dimensional beings are not aliens; the fifth-dimensional beings are humans from the far, far, far future, who have evolved beyond the limits of the third dimension. These far future humans are now helping to create themselves by giving humanity the wormhole to a new galaxy.
What happened to Cooper's son Tom in Interstellar?
He and other faithful farmers stayed as "caretakers" for the last humans to leave the planet, unimpressed with the "useless machines" that would redefine civilization. Tom's death in his eighties was likely peaceful.
Erin Cooper is Donald's daughter, Cooper's deceased wife and the mother of Murphy and Tom. She died of a brain cyst that went undetected due to MRI machines no longer existing. Joseph Cooper describes her as "the calmer one".
Brand is on his deathbed and after Murph finds out that he thought the equation was unsolvable, she asks, "Did my father know? Did he leave me?" then Brand says, "Do not go gentle." Why? 'Do not go gentle' is from Dylan Thomas' famous poem, Do Not Go Gentle Into that Good Night.
What data did Cooper send to Murph by morse code by the watch? The data from the black hole that Murph needed to solve the equation to manipulate gravity.
