This book, which addresses the grand and fundamental question of “Where did the universe come from and where is it going?”, is similar to the primal question we often ask, “Where did we (humans) come from and where are we going?”
So maybe more people are reading it with interest.


The core of this book also begins with these fundamental questions.
This book mainly deals with the unification theory of space science and physics.
To make space science, which is of greatest interest to the general public, more readable, some of the technical content covered in A Brief History of Time has been removed.
Nonetheless, it may be considered a more complete book in that it covers the core of the original book in greater depth and detail, adds new information, and inserts observations of new theories.
