From the ancient cosmologies of Thales and Plato,
Great discoveries by Galileo, Newton, Einstein, etc.
Up to the latest astronomical theories and issues, including quantum mechanics and string theory.
A variety of space stories accessible and fun through comics.

“Those who read this work will surely fall in love with astronomy.

“This is a completely new genre of work, clearly distinct from existing science textbooks!” - Ji Woong-bae (Space Dust)

The author, who has been using his own unique style to explain unfamiliar and difficult subjects such as philosophy and brain science in an easy and fun way through comics, has now presented an educational comic that richly captures the infinite world of space and astronomy.

If you are a beginner in astronomy who has become interested in space because you love space, you will probably have some questions.
How did ancient people imagine the universe? Why would anyone want to study astronomy? Why does philosophy intersect with the study of astronomy? How does astronomy differ from physics? … Astronomy is the science that studies the universe and its phenomena—stars, planets, galaxies, black holes, and more—through observation and theory.
However, astronomy is a field that is closely connected to various fields of study, such as philosophy, mathematics, physics, and quantum mechanics, and is, as the author says, a "huge pie" discipline that "embraces" many fields.
So how did the author portray this vast realm of astronomy?

This book is an educational comic book designed to provide a glance at the flow of astronomy, from the cosmology of ancient philosophers to cutting-edge modern theories.
Theories and quotes from scientists and astronomers, various scientific terms, and pieces of knowledge scattered throughout the vast universe have been meticulously compiled and compiled in a way that anyone can easily understand.
From the cosmology of ancient Greek philosophers such as Plato, Aristotle, and Pythagoras, who laid the theoretical foundations of astronomy, to the astronomical discoveries of great scientists who raised 'big' questions about the universe and celestial bodies, to the latest astronomical theories and issues from theoretical physics such as quantum mechanics and string theory, these 'small pies' selected from this vast array of stories are woven together in a pleasant and sophisticated way with sensuous drawings and witty dialogue.

Since the first humans looked up at the night sky, it has been one of nature's most wondrous objects.
As Aristotle said, wonder is the beginning of knowledge.
All curiosity grows from admiration.
So, all learning is a flower that blooms from this one word.
… Reading astronomy is a science fiction experience that transcends the finite human intuition and embraces the worldview of the infinite universe.
Whenever I think about this, I think of the tagline from the movie The Matrix Reloaded:
“Whatever you imagine, you will see more than that!”

A baby's first leap begins the moment it first expands the boundaries of its universe.
I thought there was only my universe in this world, but I realized that you also have your own universe.
My universe expands as much as yours, and our universes become more abundant as we embrace each other.
Becoming an adult is a process of expanding the fence that is ours by bringing in something different from us.
--- From "We were once the center of the universe - Ancient cosmology"

Throughout human history, no idea has been as important or as shocking as the heliocentric theory.
Not because it revealed that the sun is the center of the universe, but because it revealed that the earth is not the center of the universe.
We live in the same world physically, but we experience different worlds psychologically.
A person's worldview determines his or her way of thinking and attitude toward life.
If so, perhaps the universe I envision is my own image.

‘An apple falls to the ground, but why doesn’t the moon?’ ‘Why doesn’t the moon fall but revolves around the Earth?’ … In fact, the moon is not not falling, it is falling.
What does that mean?
Let's say Mario throws an apple horizontally.
No matter how hard you throw the apple, gravity will pull it down and it will fall to the ground.
But let's say Mario gets super powers.
If you throw the apple harder and harder, it will follow the Earth's circular trajectory and eventually go around the Earth!

There is no absolute standard for saying that 'a cat moves at 10 km/h'.
We can only say, 'The cat passed me at 10 km/h' based on a relative object.
(And this is equivalent to saying 'I ran past the cat at 10 km/h.')
--- From "Einstein, the Beginning of a Legend - Special Theory of Relativity"

There is a symbolic experiment that is always mentioned when explaining quantum mechanics.
Have you heard of the double slit experiment? ... The double slit experiment is an experiment that fires electrons toward two slits.
The detector observes which of the two slits the electron passed through.
…fires electrons one by one toward the double slit.
If you shoot electrons with the detector turned off (without measuring which slit the electrons pass through), an interference pattern will appear on the opposite screen.
The strange thing is that when you turn on the detector (to see which slit the electron goes through) and shoot an electron, the electron only goes through one slit, either the right or the left, and two long lines are created on the opposite wall.
Can we, using common sense, accept that if we measure an electron, it passes through one slit, and if we don't measure it, it passes through both slits simultaneously?

String theory explains the properties of various particles in terms of the vibration patterns of strings.
All strings are the same, but different strings have different masses and different force charges depending on their vibration patterns.
“It’s similar to how different music comes out depending on the vibration pattern of a violin string.
String theory is also similar to music.
So it feels more beautiful.”
