Space Quanta and Existence Waves: Interpretation of Dark Matter and the "Third Existence Wave" Hypothesis

In modern cosmology, the identity of dark matter, which is estimated to account for approximately 27% of the universe's energy density, remains unsolved. This paper presents a new hypothesis regarding the identity of dark matter using the framework of the unique theoretical system: "Space Quanta and Existence Wave Theory." Specifically, by assuming the existence of a "Third Existence Wave" that possesses a communication protocol different from that of matter derived from observable electromagnetic waves, and by employing the analogy of "OS (Space Quanta) and Application (Existence Wave)" from computer science, we logically explain why dark matter "possesses gravitational interaction yet is completely undetectable by electromagnetic observation." This hypothesis does not immediately deny existing dark matter candidates (WIMPs, PBHs, etc.) but is positioned as an "Unconceived Alternative" from the perspective of computational cosmology—serving as a theoretical redundancy (backup) in the event that the detection of existing candidates ends in failure. ———This paper is part of the Space Quanta and Existence Wave Theory (空間子と存在波理論) series. The same theory is presented for a general readership—with considerably different wording and structure—in the book Engineering the Universe, available on Amazon KDP (https://www.amazon.com/dp/B0GZHTKFND).
