Interstellar Questions Answered
This article answers a lot of questions which you may find are “unanswered” after seeing Interstellar. If you have not seen the movie, I would highly recommend seeing it! If you have already seen the movie, did you feel a bit confused after the end? Like me, did you feel like polling people around you in the movie theater to see if they understood the ending?
Interstellar Questions Answered
1. Why Should You See Interstellar?
According to the Merriam-Webster dictionary, the definition of interstellar is: located, taking place, or traveling among the stars.
The movie, Interstellar, is well-directed, well acted and has an interesting storyline. Although sometimes bleak, the well-crafted cinematography and action-packed scenes made for a very good movie. Although the movie is lengthy, running approximately 2 hours and 50 minutes, it holds your interest and has several “sit at the edge your seat” scenes. This is the kind of movie that makes you think out of the box. You end up thinking about things you would never normally think of. It also provides an imaginative look at what it would actually be like if you traveled through a wormhole in space.
2. What is the Name of the Spacecraft Used for the Astronaut Team to Explore Other Planets?
The main spacecraft used in the movie for the astronauts is called Endurance. It has a rotating ring encompassing 12 pods, once of which links to the main cockpit for the Endurance crew team. It has hyper-sleep chambers for the crew members for their 2-year journey from Earth to Saturn’s orbit, which is where the wormhole is located.
3. What is Plan A vs. Plan B to Find a New World?
Plan A: Use 5th dimensional physics and use gravity to launch a space station big enough for the entire world to be on. In order to achieve this, astronauts must first travel through a wormhole in space. This plan saves the population on Earth. In the movie, Michael Caine’s character (Dr.Brand) believes this is impossible, but he does not divulge this until later on the movie, when he is on his deathbed.
Plan B: Use frozen embryos to populate a planet and start a new colony from scratch. This plan leaves everyone on Earth stranded and does not save the current population on Earth. It was a backup plan in the event that Dr. Brand could not figure out the gravity equation necessary to accomplish Plan A.
4. What Are the Planets That The Astronauts Visit and Explore?
Miller – This is the first planet visited by the crew of Endurance (the interstellar spacecraft that transports Joseph Cooper, Amelia Brand and the others on the crew through the wormhole); this planet is covered by water and inhabitable. This planet was previously visited by NASA but a tidal wave was encountered and the previous crew did not survive. Time is very different and distorted on this planet, so when the crew visits the planet, every hour they spend on the planet is equal is approximately 7 years on Earth. When Cooper (Matthew McConaughey) and Brand (Anne Hathaway) return to orbit, 23 years have passed on Earth.
Mann – This is the second planet visited by the Endurance crew. It was named after Dr. Mann, who was the first astronaut to land there. This planet is an ice planet that orbits the black hole which they call Gargantua. It has 67 hour days and 67 hour nights. When Cooper and Brand land on Mann, it appears to be an abandoned. However, they then discover a sleep chamber and Dr. Mann is inside, and alive. He had been marooned there for 35 years, and although he has not aged much physically, the abandonment has affected his mental health. Dr. Mann is played by Matt Damon.
The most surprising part of the movie for me is when Cooper (Matthew McConaughey) and Dr. Mann (Matt Damon) are exploring and Dr. Mann attacks Cooper and tries to force him off an icy cliff. Dr. Mann was keeping something a secret: that there is no surface on the Mann planet. Also, Mann is aware that Dr. Brand (Michael’s Caine’s character) believes that Plan A is not possible; therefore, Dr. Mann wants to leave the planet and seek out another new world. After Dr. Mann leaves Cooper for dead, Dr. Mann takes off in his ship, and attempts to travel to the main spacecraft, Endurance, to take control of it and leave all the others behind.
Meanwhile, Cooper manages to crawl to a spot where an emergency device was located and he contacted Brand (Anne Hathaway), who rushes there to save him. Cooper and Brand then rush to their ship and try to beat Dr. Mann to the main ship. Dr. Mann tries to line up his ship to the main ship and interconnect but he fails. He then opens his hatch and the pressure causes an explosion, killing Dr. Mann. Cooper and Brand manage to line up their ship to the main ship and connect successfully, despite the fact that they are spinning. Cooper then makes a surprising decision: To jet off alone and leave Dr. Brand behind. To see what happens next, see the question below entitled “What is the 5th Dimensional World Found By Cooper?”.
5. What Planet Was Not Visited By Endurance Because They Did Not Have Enough Fuel?
Edmonds – This planet is named after Dr. Wolf Edmunds, who was the first astronaut to land there. After the crew returns to Endurance after their failed landing on the Miller planet, Cooper announces that they do not have enough fuel to visit both Mann and Edmunds. Brand (Anne Hathaway) is supposedly in love with Dr. Wolf and begs Cooper and the other crew member to pick Edmunds, who she also feels is better for human population. The crew votes and they end up selecting to visit the Mann planet.
6. What is the 5th Dimensional World (Tesseract) Found By Cooper?
After leaving the Mann planet, Cooper jets off by himself and finds a 5th dimensional world. This can be referred to as a tesseract (a four dimensional hypercube with 16 sides). He is trapped inside of the multi-dimensional world, but he discovers that he can see through the walls and sees his daughter, Murphy at a young girl and as an adult, in her bedroom. As a young girl, Murphy believed there was a ghost in her bedroom and that it was trying to communicate with her, but they (Murphy and her dad Cooper) discover that it is not a ghost; instead, it is an unknown intelligence sending coded messages through gravitational waves, which identify binary coordinates which leads them to Professor Brand at a secret NASA location (that was how Cooper ended up at the secret NASA location when Murphy was 10 years old, and when Professor Brand tells Cooper that he wants him to be the head pilot to save the world).
While in the tesseract, Cooper is able to communicate with his adult daughter by sending her Morse code through the second hand of her watch. Once Murphy receives the codes, she realizes that her father (Cooper) is communicating with her from beyond. Murphy returns to the NASA station and uses the Morse code signals to complete the equation which Professor Brand was unable to figure out. Murphy yells Eureka! and at that point, mankind is saved as they begin to put Plan A in motion.
Meanwhile, Cooper then finds himself out of the 5th dimensional world and instead, floating in space. Cooper then wakens in a hospital in the new world. It is not explained, but approximately 60 years has passed and Cooper, although not aged physically, is told by a doctor that he is 124 years old. It is assumed that during that time, stations were being built on Saturn to save humanity. The doctor explains that space rangers rescued Cooper minutes before his oxygen was about to run out.
7. What is the Difference Between a Worm Hole and a Black Hole?
According to NASA, a black hole is an invisible place in space where gravity pulls so much that not even light can get out.
In the movie, Interstellar, worm holes are described as a shortcut to jump from point A to point B in space. It’s sort of like a subway, to get somewhere faster than other means. It’s also explained like this: think of a piece of paper from point A on one end, and point B on the other end; if you fold the piece of paper in half then you can easily get to point B. In the movie, the Endurance spacecraft enters a wormhole to reach Miller's planet.
Interstellar Featurette - Building A Black Hole (2014)
How Does the Interstellar Movie End? (SPOILER ALERT!)
When Cooper awakens is in the hospital many years later, the movie doesn’t explain where they are. This is the confusing part. The doctor explains that Cooper can soon reunite with his daughter, Murphy, who is now an elderly woman. Cooper soon enters the room where an elderly Murphy (played by Ellen Burstyn) is overjoyed to finally see her father. Cooper is also amazed and overjoyed to see his daughter after all this time. Murphy, barely able to speak, tells Cooper to go find Amelia on the Edmunds planet.
At one point, Cooper hears some noise outside and looks out the hospital window. There is a baseball game being played nearby. This is the new world, and humanity is now living on the planet Saturn, in the 5th dimensional world (at least I think it's Saturn?).
Cooper then decides to go find Dr. Amelia Brand. He takes a spacecraft and heads to Edmunds. The final scene shows Amelia Brand (played by Anne Hathaway) on the Edmunds planet, at the grave where Dr. Edmunds is buried. She appears to be alone on the planet, but then nearby they show a camp.
Final Thoughts and Questions:
Do Joseph Cooper and Amelia Brand re-unite?
Does Cooper take Amelia back to the new world on Saturn?
Is the new world actually on Saturn?
How did the elderly Murphy know that Dr. Amelia Brand was on Edmunds?
What are space rangers and how did they transport Cooper to the new world after he was rescued?
After Cooper was rescued, where was he when the 60 or so years pass when Murphy was aging and stations in the new world were being built?
At the end of the movie, when they show the new 5th dimensional new world, where is the sky?

Commentaries on Interstellar From Neil DeGrasse Tyson
Neil DeGrasse Tyson, is an American astrophysicist, cosmologist, author, and science communicator. He is also host of Star Talk Radio Show.
According to Neil DeGrasse Tyson, we know there are worm holes, but we don’t know how to create them. In black holes bad things happen. You travel through worm holes, but not through black holes. You might be able to go around a black hole, but if you travel to the center of it, you will probably not survive.
In regards to the movie, Interstellar, the science of the movie was very ambitious. They had a science advisor named Kipp Thorne. Coincidentally, one of the robots in the movie was named “Kipp”.

Wow, thanks Squidjam, I appreciate your comment and answers to all the questions, thanks!
Squidjam on June 26, 2015:
Remember the structure NASA was building? It's a station. Remember where the wormhole was? Near Saturn. The only thing they couldn't figure out was gravity, but once Cooper sent Murph the data through the watch, they were able to, hence Eureka. The station, one of many, is headed to the wormhole, to inhabit Edmund's planet. But Cooper is going ahead of them in one of the Space Rangers (the flat looking craft) to meet Brand, who is in cryo-suspension. It may take them much more time to arrive there so Cooper follow's Murph's advice. The stations are cylindrical and rotate to simulate gravity, hence no sky. Sunlight is brough upon using mirrors, changing orientation to simulate daytime and night. The fifth dimension is only the teseract, a physical representation of time. The 60 years are time dilation suffered by Cooper going near Gargantuan. I hope this answers your questions. Cheers.
Dave on May 31, 2015:
You're very welcome. It is indeed a great movie.
I also enjoy how modern movies are bringing 'theoretical physics' to a 'believable reality', what great times we live in!
However, in the movie ( and most other sci-fi films that describe how 'worm holes' are used for interstellar travel ) I'm not so sure on the explanation of a worm hole using the folding of space time to go from A to B as described by using a pen and piece of paper to bring the two end points together without travelling through the part in the middle. I understand the suggestion, however for me its not believable that you can take such a physical short cut and it would require some kind of tear or actual hole in the fabric of space time itself that you wouldn't physically be able to be in . Something just as fantastical and possibly more believable would be if the worm hole was described as a compression of the space time in front of you and a stretched space time behind you. For eg... if you compressed the space of 10 miles in front of you to just one foot of space then you only have to make one small human sized step to travel that one foot of which you would then relatively travel 10 miles. If you then scale that up to billions of miles then a more believable explanation of a worm hole ( and also interstellar travel ) has been theorised and it has also been done without breaking any known laws of physics with respect to tears or holes in the fabric of space time.
I just thought that I would share that thought :-)
Amelia Griggs (author) from U.S. on May 31, 2015:
Thanks for your comment and answers to Renee's questions. Much appreciated that you took the time to explain and provide more detail to the many mysteries in this movie. :-)
Dave on May 30, 2015:
The 'others' that Anne touched was actually Cooper on his way out of the black hole. It makes sense as he would still be moving through dimensions on his way out.
Cooper was able to go back in time to his strongest emotional space time - the time and place around when he was last with his daughter. The tesseract was a 3 dimensional representation of all time but only at that emotional place. While in the tesseract Cooper learned that gravity can be felt through all of space and space time so he got the quantum data from TARS and manipulated gravity where the watch hands are. The watch hand moved via gravity to represent morse code. Remembering that gravity persists through time, when Murph returned to the house years later she found the watch with the moving hands and decoded the data.
Amelia Griggs (author) from U.S. on April 24, 2015:
Thanks for your insight, Sebastian. There is so much to this movie that they don't explain. I understood more after I saw it, researched it, and thtough this thread!
sebastian on April 24, 2015:
I believe the station near saturn is only temporary and they plan to eventalyy meet up with brant on edmunds(the planet).
Murph probably knows about their story because brant sent more messenges.
Cooper spent much time in the gevitational field of the black hole, which warps time! Thats 60ys in a blink.
Amelia Griggs (author) from U.S. on March 23, 2015:
Thanks Brian, this is very helpful! It makes sense more now about no sky, and circular ground, pretty interesting and amazing, thanks again for the info.
Brian on March 23, 2015:
Very nice summary. You missed a key point near the end. They were not on Saturn but on a giant space station orbiting Saturn. This station used the new Gravity technology and was s giant hollow cylinder. The "ground" curved over and up overhead...this is why no sky. The way Cooper got the info was that TARS was in the Terreract with him and got the data. Does that help? And yes, Cooper went to be with Brand.
Amelia Griggs (author) from U.S. on February 18, 2015:
I know what you mean about how Cooper ended up in the 5th dimension There are various unanswered questions in the movie. That's why at the end of the movie I felt like standing up and having a discussion with the other people in the movie theater because I had so many questions. that's what prompted me to create this home and tried to answer some of the questions that left people confused.
His daughter's room in the house is the key I believe to how the fifth dimension was reached. The part with the Morse code is quite confusing. You almost have to watch the movie a second time to understand it better.
To understand wormholes a bit you can look at the videos I included where they are discussed by Neil Degrassi Tyson.
After watching the movie when I got home I cannot explain it but I was like a fanatic looking up information online to try to understand everything. I understood more but I don't think a hundred percent of all of our questions will be answered and some are just mysteries.
Hope this helped include you found the article helpful.
Renee on February 18, 2015:
What I don't understand is how Cooper ended up in that 5th Dimension and he was able to go back in time ( Which is what it looks like, since after all he was the one sending the codes to his daughter) and give her those codes, where did her get the codes? I am super interested in Astronomy and Physics but it juts doesn't add up. Scientifically, this movie was made to really show what it would look like if we were to move around space and what everything would look like. My other questions, who placed the wormhole there, but they clearly say it showed up there. When Anne got touched by the so called "others" are these Humans who live in a different Dimension who have better technology than we do? It's just insane. I want all of these questions answered, but it just seems impossible.
Amelia Griggs (author) from U.S. on January 12, 2015:
Thanks, rebekahELLE, I would highly recommend seeing the movie soon while it is still in theaters. Once you see it, tgen you might want to come back and read the rest of this hub which will answer some questions...at the end of the movie I was inclined to ask others in the theater about some confusing parts. I think there was just not enough time to explain everything and it does leave you thinking.
Hope you see it. Thanks for stopping by. :-)
rebekahELLE from Tampa Bay on January 12, 2015:
I haven't seen the movie yet, so I didn't read the entire hub. But what I read is interesting and definitely peaks my curiosity further to want to see the movie. I'm a fan of Christopher Nolan and enjoy his films. The subject matter of Interstellar has always fascinated me. There's so much we don't know and yet so much we do know that isn't put on the big screen like this one. I'm looking forward to seeing it. I like the way you answered specific questions. Well done.
Amelia Griggs (author) from U.S. on December 30, 2014:
Thanks again, Catherine. I agree that the Astrophysicists did an impressive job. I think because they had help from a real scientist, it made a difference, but possibly made it a bit too complex at times. It should be interesting to see what kind and how many awards this movie gets.
Your comments are most appreciated.
Catherine Giordano from Orlando Florida on December 29, 2014:
It's not fault I don't understand. Astrophysics is way beyond me. You did a great job.
Amelia Griggs (author) from U.S. on December 29, 2014:
Thanks for being honest, Catherine. To be honest, although I thought the movie had great acting and it was believable to a point, since I am the type of person that likes to figure things out, I found myself a little lost at the end, and when I went home, I watched a bunch of "explaination" videos on youtube on my smart TV, trying to understand everything. That helped me a lot and prompted me to share my information for others who may also be confused by some scenes. The trailers that I watched "before" seeing the movie didn't tell me a lot and didn't help me decide if I wanted to see the film. I read a lot of reviews and it seemed to be a good choice. The movie theater I went to was packed. Everyone watched closely and intensely. It's a very ambitious film, I must say!
Catherine Giordano from Orlando Florida on December 29, 2014:
I still don't understand the movie. Nice try tho.
Amelia Griggs (author) from U.S. on December 29, 2014:
Thank you, indianreel. I appreciate your comment and glad you liked the hub. I had a feeling that a lot of other people who saw this movie had the same questions I had, so I wanted to share what I discovered and know and hope that others chime in and let me know what they think about the movie.
HK from London on December 29, 2014:
This is a great hub. Very good questions. Straight and unambiguous answers.
