Discover the secrets of the Universe

and decode the Theory of Everything
Theory of Everything – Mathematical universe and the golden ratio
Released: March 2026

Have you ever considered that the universe we live in might be only half the story? Have you ever wondered where you come from, how the universe began, and what the future holds? The journey to answers begins with asking the right questions. Sometimes stories and puzzles can show us the way. What begins with a simple riddle, or a seemingly innocent question like “What is 0⁰?”, can open the door to deeper questions about mathematics, physics, quantum uncertainty, and the origin of the cosmos.

In Theory of Everything – Mathematical Universe and the Golden Ratio, Darko Sifrer explores what happens when energy and mass become equal, uncovers the remarkable mathematical Phi–bonacci sequence with infinite precision, and reveals how rounding in our physical universe occurs.

If Einstein had read this book, he might have reconsidered his famous claim that “God does not play dice with the universe.” As Sifrer suggests, nature not only plays dice—it shuffles the cards as well. Probability, after all, is a fundamental part of mathematics.

Theory of Everything - Beyond Einstein's Equation, c² = E/m
Released: May 2025

What if nature whispered the secrets of the universe through numbers, riddles, and dreams? Discover a bold and playful journey beyond the known in the Theory of Everything book series.

In this first volume, the author turns Einstein’s iconic equation on its head—literally. By inverting E = mc² to c² = E/m, he uncovers new and astonishing insights that bridge science, mathematics, and imagination, redefines the light and its speed, and challenges everything we were once taught in school.

Explore 64 thought-provoking chapters, each revealing how the impossible might just be possible, and challenge long-held beliefs to see how truth can be both right and wrong at the same time. Discover the beauty of mathematics—hidden in nature, chessboards, symmetries, paradoxes, and galaxies.

This is not just a book of ideas—it’s a mosaic of revelations. By connecting each piece, Sifrer builds a visionary path toward a deeper understanding of the universe around us and the nature within us.

If Einstein had read this book, he might have rewritten his equation.

Darko Sifrer

a mathematician, chess master, inventor, member of Mensa, author of the Theory of Everything book series

A love of numbers and a sparkle of curiosity led the author, Darko Sifrer, to the idea of reversing and expanding Einstein's equation - an elegant, yet revolutionary step that lead us to surprising insights about the universe.

Darko Sifrer (b. 1956) graduated from mathematics at University of Ljubljana and became a recognized international chess master in 1991. During his professional career, he provided expert mathematician and financial advice to many Slovenian and former Yugoslavian companies and worked as a court expert. His childhood desire to understand the mysteries of the universe eventually led him to study physics and quantum mechanics, connecting the missing pieces of the puzzle of the universe together. He loves playing boardgames and inventing new ones, as much as he enjoys sitting on his bench, observing nature, the sunset, and the bees flying around a cherry tree.
