The Cosmic Thinker’s and Essayist’s Notebook

🪐 A Questioner for the Survival of the Universe
📖 Reading to grasp the axis of history,
📜 Designing the future of civilization through policy,
🔭 Sowing seeds of thought that will endure even 100,000 years from now.

“The universe continues to expand, and so does my thinking within it. To be alive—this itself is my mission.”

“Welcome to a small planet for those who question life and civilization from a cosmic perspective, and for those who share the curiosity.”

My Reflections on the Multiverse

A short essay on nine types of multiverse inspired by Brian Greene’s The Hidden Reality

1. Mathematical Multiverses: The Quilted Multiverse and the Ultimate Multiverse

The Quilted Multiverse envisions an infinitely vast cosmic expanse in which every possible event occurs somewhere. The principle of fecundity naturally applies here, making this concept not far removed from the Ultimate Multiverse. If mathematics is the only way to conceptualize infinity, then the Quilted Multiverse could be a strong candidate for the Ultimate Multiverse—a reality grounded in mathematical equations. In such a cosmology, the observable universe becomes irrelevant, for it is finite in both space and time.

2. String Theory Multiverses: Brane Multiverse, Cyclic Multiverse, and Landscape Multiverse

Assuming string theory is correct, three prominent multiverse models emerge. Of these, I would give the most weight to the Landscape Multiverse, which combines the Inflationary Universe Theory—supported by extensive cosmological observations—with String Theory, itself a mathematical unification of General Relativity and Quantum Field Theory, both of which have been validated countless times through experiments and observations.

3. A Reinterpretation of the Simulated Multiverse

My personal stance is that a universe wholly governed by computer simulation does not exist. However, from a solipsistic perspective, if our brains were influenced by an external machine civilization, and if this influence were seamlessly integrated with artificial intelligence, then we could redefine the concept as a “New Simulated Multiverse”—a simulation multiverse rooted in Transhumanism.

4. Final Reflections

While reading this book, I hoped to encounter an entirely new framework of knowledge. I read it closely, but in the end, I was left with a sense of incompleteness, as though the ideas had not been fully assembled. My curiosity and expectations for the multiverse were high, so my disappointment upon confronting its speculative nature was equally great. Yet, as part of my duty as a cosmic being, and as a cosmic thinker and essayist, I will continue striving to deepen my understanding of the universe.
