Author's Note Postscript

Interstellar, a passage to another universe, has already become a reality!
Who can draw the boundaries of scientific imagination?

Could "Nine Days of Space Travel" and the movie "Interstellar" possibly have such a parallel? The author and protagonist is a former French soldier and farmer.
The main character of the movie is also a farmer with a military background.
The book's content consists of an experience of visiting the ideal planet Thiaoouba at the invitation of a superhuman alien.
The principles of supersonic space travel, wormholes, environmental pollution and the crisis of Earth's civilization, descriptions of the beautiful planet Saturn, 12 astronauts, the immortality of the soul, and dimensional travel are all similar to those in the movie 'Interstellar'.
In terms of scientific plausibility, such as parallel movement and body changes, it actually surpasses 'Interstellar'.
'Interstellar' even answers questions about Jesus, who is shrouded in mystery.
The protagonist presents an alternative for humanity by incorporating even the problems of the human world into 『9 Days of Space Travel』.

Dr. Max Tegmark of MIT argues that “four parallel universes exist layered like layers of an onion.”
If you go to the fourth level of parallel universe, a universe that seems to be a duplicate appears through a wormhole (a hole in the wall of spacetime connecting a black hole and a white hole).
The universe created through a wormhole becomes a second-generation universe.
According to Dr. Max Tegmark, an authority on parallel universes, there are beings just like us on Earth in universes we cannot see.
If we view the universe we are seeing as 'the space-time through which light reached Earth 13.8 billion years after the Big Bang,' then the end of the universe is nothing more than what it looked like 13.8 billion years ago.
The end of the universe can only exist in our imagination.
Just as my reflection in a mirror appears different depending on symmetry or anti-symmetry, the universe is a circle that repeats and is symmetrical, transcending time and space to take on different appearances.
Reincarnation can also be explained by parallel theory.
So, as in books and movies, wouldn't it be possible for a future self to send a message to today's self? Wouldn't we be calling him a transcendent being? If we close the door to the scientific possibility of parallel universes, we must also close the door to the possibility of God.
The protagonists of the book and the film embark on a journey across parallel universes and dimensions.
Whose journey is real?

At midnight on June 26, 1987, a former military farmer named Michel Demarques left home in Australia, leaving only a note for his wife saying he was going on a long trip.
Then he met a superhuman alien named Tao and was sucked into a parallel universe.
Returning home after nine days, he tells his loving wife and child about his amazing experience.
He had been to Thiaouba, the planet of the beautiful, superhuman alien Tao.
His story is a message to humanity from higher-dimensional aliens tasked with enlightening Earthlings.
The author says he took great pains to describe the story of the alien Tao as objectively and accurately as possible.
This book covers a wide range of topics, from faster-than-light space travel and the principles of parallel universes to the origins of humanity and races, the continent of Mu and its pyramids, the continent of Atlantis, the protagonists of the Easter Island statues, planets destroyed by nuclear war, the Creator and the Big Bang, levitation and telepathy, the immortality of the soul and reincarnation, the appearance of Jesus Christ, environmental pollution, and the crisis of Earth's civilization.

Published in Australia under the title 'Thiaoouba Prophecy', the book generated such a huge response that it was translated into many countries, including the United States, Japan, Spain, Poland, Germany, Sweden, Russia, and Portugal.

“They all came here by chance.”
“By chance? What does that mean?”
“It’s very simple.
Have you heard of the 'Bermuda Triangle'?
I nodded.
“Simply put, there, and in other lesser-known places, this parallel universe (also called a twin universe) overlaps with yours, creating a natural warp (a spacetime distortion zone that allows faster-than-light travel).
And any person, animal, or object that gets too close to the warp will literally be sucked into it.
For example, even a huge fleet of ships can disappear entirely in a matter of seconds.
Sometimes, some people return to your universe after a few hours, days, or even years, but most never return.
If someone who has returned to Earth were to tell about their experiences, most people would not believe them.”
Tao continued.
“There is a representative case regarding a passage into a parallel universe.
A young man went to draw water from a well a few hundred meters away from his home and disappeared without a trace.
After about an hour, his family and friends went out to look for him.
Since the snow that had fallen during that time had piled up to about 20cm, finding it would have been easy.
Because you just have to follow in that young man's footsteps.
But the footprints were cut off in the middle of the field.
Some people believed that the young man had been abducted onto a spaceship.
But the poor young man was simply sucked into a parallel universe.”

Can we find the answer to save ourselves?

If there are aliens out there trying to enlighten the mentally devastated Earthlings, wouldn't they be sending us a message in some form?
They are conveying the message through an Earthling that 'humans exist on Earth to learn how to live, how to die, and to develop spiritually to the fullest extent.'
The shadow of destruction is hanging over the world due to global warming, depletion of resources, environmental pollution, and the hollowing out of the world economy caused by the corporatization of religion.
Material civilization must develop to foster spiritual maturity, but on Earth, material civilization dominates spiritual civilization, causing many problems.
Just as Cooper, the protagonist of 'Interstellar', set out in search of hope for his beloved family and the larger family of humanity, we too must ponder deeply whether we can find the answers to save ourselves for a greater future.
