Welcome to the world of relativity!
Everyone wonders what relativity is all about. Because the theory of relativity predicts
phenomena that seem unbelievable in our everyday lives (such as the slowing of time and
the contraction of the length of an object), it can seem like mysterious magic.
Despite its surprising, counterintuitive predictions, Einsteins theory of relativity has been
confirmed many times over with countless experiments by modern physicists. Relativity and
the equally unintuitive quantum mechanics are indispensable tools for understanding the
physical world.
In Newtons time, when physicists considered velocities much smaller than the speed
of light, it was not a problem to think that the measurement of motion, that is, space and
time, were independent, permanent, and indestructible absolutes. However, by the end of
the 19th century, precise measurements of the speed of light combined with developments
in the study of electromagnetism had set the stage for the discovery of relativity. As a result,
time and space, which had always been considered to be independent and absolute, had to
be reconsidered.
That’s when Einstein arrived on the scene. Einstein proposed that time and space were
in fact relative. He discarded the idea that space and time were absolute and considered that
they vary together, so that the speed of light is always constant.
This radical insight created a controversy just as Galileos claim that Earth orbited the
Sun (and not vice versa) shocked his peers. However, once we ventured into space, it was
obvious that Earth was indeed moving.
In a similar way, relativity has given us a more accurate understanding of concepts
regarding the space-time in which we are living. In other words, relativity is the result of
asking what is actually happening in our world rather than saying our world should be a
particular way.
Although this preface may seem a little difficult, I hope you will enjoy the mysteries of
relativity in a manga world together with Minagi and his teacher, Miss Uraga. Finally, I’d like
to express my deep gratitude to everyone in the development bureau at Ohmsha; re_akino,
who toiled over the scenario; and Mr. Keita Takatsu, who converted it into such an interest-
ing manga.
Well, then. Let’s jump into the world of relativity.
