This paper, titled "Dimensionality Extension: Numerical Ranges of Conditions Triggering Parallel Worlds," is authored by Li Ji and Li Zhibin from Qiankeng Middle School, Jiexi County, Jieyang City, Guangdong Province, China. The study investigates the numerical frequency and energy conditions required for subatomic particles to trigger parallel world transitions. It presents observable experimental phenomena, including atomic replication and divergent emission (Phenomenon 1) as well as the temporary manifestation of identical atoms across different probability clouds in past, present, or future timelines (Phenomenon 2). The paper provides a theoretical explanation of parallel universes as a consequence of dimensional ascension and localized spacetime softening, which allows consciousness to exert tangible effects on physical matter. It further specifies the numerical ranges for atomic strike frequency (1.76 × 10^30 Hz ≤ f ≤ 1.76 × 10^44 Hz) and strike energy (based on Planck and reduced Planck constants), with the lower bound already achievable via current pulse technology. The authors also share their personal perceptual frequency range, derived from firsthand experience of inadvertently entering a parallel world. The author's own soul perception frequency is 1.76 × 10^44 Hz, allowing the perception of information at frequencies up to 1.76 × 10^44 Hz. This work offers a fresh perspective on parallel universes and proposes a testable hypothesis for future experimental validation. The authors acknowledge their status as ordinary high school students with limited resources, yet their core focus remains on the development of Dimensionology.
