“Shimokitazawa Time Slip,” “Kisaragi Station,” “Future people appearing on social media” — investigating and taking on these hot-topic spacetime moves with cutting-edge physics!
Are the time-leaps and otherworld experiences rumored online merely urban legends? This book examines them based on state-of-the-art physics and neuroscience. And it derives a unique spacetime theory that “the self (consciousness) might be gravity.”
If the true nature of the self is gravity—
If only gravity can cross dimensions—
Might consciousness be able to move through time as if it were space?
To test that hypothesis, we conducted large-scale experiments!

▸ Cases where precognitive dreams came true
▸ Reports of simultaneous experiences by multiple people
▸ Examination of cases that nearly produced physical evidence
Juxtaposing scientific theory with primary sources, this work tackles the possibility of time-leaping head-on.
Furthermore, cases of frequent time slips in Shimokitazawa and eyewitness reports of “Kirishima Station,” said to be a second “Kisaragi Station,” over 20 mysterious experiences are also included.
The author, who conducts independent research into mysterious spacetime phenomena, has spent approximately 10 years collecting cases and carrying out investigations and experiments, delivering an unprecedented piece of science entertainment.
This is Japan’s first time-leap research book, compiling the results of 10 years of time-leap research by BTTP. Mixing theory with real-world examples, it gets to the heart of the mysteries of time travel and parallel worlds.
This book complements “The Window of Opportunity A Guidepost to the Mandela Effect — The Ultra-Secret X Files” and allows you to understand in depth the relationship between the Mandela Effect and time-leaping.
An introductory book on time-leap research that combines real-world cases collected from around the world with the latest insights from physics and quantum mechanics, scientific and comprehensive in scope.
