PASCOS 2025: 30th Symposium on Particles, Strings and Cosmology, from July 21-25 hosted by the Institute for Particle Physics Phenomenology at Durham University in Durham, England, UK. This symposium reviewed progress in particle physics, astroparticle physics, string theory and cosmology, with particular emphasis on their interconnections. Dark Matter and Dark Energy, string theory methods and phenomenology, neutrino physics, precision measurements and non-accelerator probes of new physics, inflation and alternatives, gravitational waves, were among other topics reviewed.

“Big bang cosmology, reliant on an infinitely hot singularity, struggles to reconcile Planck-scale dynamics with observable cosmic structures. We propose a hyper-rational model that redefines the universe as a geometric and mathematical start and expansion from the Planck scale (10^-35 m, 10^-44 s) to the observable cosmos (10²⁶ m, 13.8 billion years) across 202 base-2 notations, all simultaneously active. Initiated by infinitesimal spheres at one per Planck Time (~10⁴³ spheres/second by Notation 143), this lattice evolves through sphere stacking into tetrahedrons and octahedrons, anchored by four irrational numbers (π, e, √2, φ) within the octahedron’s four hexagonal plates, now tentatively named, Planck Polyhedral Core. Highly-speculative, the embedded link goes to a larger image and a brief history.

These plates encode continuity-symmetry-harmony, replacing particle-centric models with a qualitative scaffold of dimensionless constants. Geometric gaps of 7.356°, arising from five tetrahedral or five octahedral configurations above Notation 60, seed quantum fluctuations, potentially manifesting as dark matter halos, CMBR power spectra, and quantum gravity’s spacetime foam. Testable predictions include gap-induced density variations aligning with N-body simulations for dark matter and Planck satellite data for CMBR, achievable through AI-driven computational geometry (e.g., topological deep learning). Unlike big bang frameworks, this model posits time as a dynamic agent, driving continuous emergence from Planck spheres to galaxies, implicating humans as participatory co-creators. We invite PASCOS 2025 attendees to collaborate on simulating these geometric structures, exploring their implications for cosmology and particle physics, and advancing a unified, mathematically coherent view of the universe.”

Brief Notes to the inner community of PASCOS:

• J. Silk, Oxford, UK (10 July 2025): Emailed Joseph Silk about galaxy formation and our exponential expansion model. Silk’s work on galaxy formation and dark matter involves cosmological scales, aligning with our model’s Notations 130–202 (macroscopic to cosmic). His broad perspective (e.g., CMB, early universe) might make him curious about our exponential framework as an alternative to inflation. Our 202-notation model offers a smooth exponential expansion from the Planck scales, potentially explaining dark matter without inflation.
• M. J. Duff, Imperial College, UK (11 July 2025): Emailed Michael Duff about our model.
• Cumrun Vafa, Harvard, USA (12 July 2025): Emailed Cumrun Vafa about our model
• Also, similar notes went to Cora Dvorkin, Eleonora Di Valentino, and Lisa Randall.

Camber Handout for PASCOS 30: https://81018.com/handout/

GoogleAI: PASCOS (International Symposium on Particles, Strings and Cosmology) is a premier conference series where leading experts, including those specializing in supersymmetry (SUSY), gather to discuss the intersection of high-energy physics, string theory, and cosmology. 

Based on the history and themes of PASCOS, here is a summary of the context regarding “significant work within supersymmetries”:

• Conference Focus on SUSY: Since its inception, PASCOS has been a venue for presenting advancements in supersymmetry, particularly its role in solving the hierarchy problem, enabling gauge coupling unification, and providing candidates for dark matter.
• Significance of Supersymmetry: Significant work discussed at PASCOS often revolves around the Minimal Supersymmetric Standard Model (MSSM), string-inspired models, and methods to detect superpartners.
• The “Met” Aspect: The conferences are known to bring together the most active researchers in the field to debate topics like SUSY breaking, R-parity, and the implications of LHC data, which often results in collaborations and discussions between key figures.
