1 Short Version External_Gravity_Cosmology__EGC__Tom 1.pdf

<b></b>We propose External Gravity Cosmology (EGC), a revised cosmological model in which the observable universe (OU) is a finite, evolving region embedded within an effectively infinite, anisotropic gravitational landscape, The Universe (TU). Unlike ΛCDM, EGC dispenses with dark energy, and a Big Bang singularity. Instead, OU structure and expansion arise from gravitational forces exerted by mass concentrations beyond our Observable Universe Event Horizon (OUEH), such as deep gravitational wells distributed unevenly across TU. This external gravitational influence induces anisotropic cosmic expansion, directional redshift modulation, and large-scale cosmic microwave background (CMB) anomalies, features that align with recent findings, including early galaxies, supermassive black holes at high redshift, and statistically significant quasar dipoles [1]. The CMB, in this model, is not a relic of recombination but a filtered radiative field shaped by intervening curvature, similar to viewing a dense forest where structure lies beyond the line of sight. EGC reframes cosmic history as a product of classical gravitational interaction and self-organization over indefinite timescales, offering a coherent and testable alternative to speculative early-universe physics. It positions gravity, not exotic fields, as the central agent in cosmological evolution, with observational consequences that extend beyond current horizons.

我们提出了外部引力宇宙学（External Gravity Cosmology, EGC）——一种修正版宇宙学模型，其中可观测宇宙（observable universe, OU）是嵌入于有效无限的各向异性引力景观——全宇宙（The Universe, TU）——之中的有限演化区域。与ΛCDM模型不同，EGC摒弃了暗能量与大爆炸奇点。取而代之的是，可观测宇宙的结构与膨胀源于可观测宇宙事件视界（Observable Universe Event Horizon, OUEH）之外的质量密集区所施加的引力作用，例如分布于全宇宙各处的非均匀深引力势阱。此类外部引力影响会诱发各向异性宇宙膨胀、定向红移调制，以及大尺度宇宙微波背景（cosmic microwave background, CMB）异常，这些特征与近期观测发现高度契合，包括高红移早期星系、高红移处的超大质量黑洞，以及具有统计显著性的类星体偶极子[1]。在该模型中，宇宙微波背景并非宇宙复合时期的遗迹辐射，而是由居间曲率塑造的过滤型辐射场，其视觉效果类似于观测视线之外存在茂密森林的场景。EGC将宇宙史重新诠释为经典引力相互作用与无限时间尺度上自组织过程的产物，为具有推测性的早期宇宙物理学提供了自洽且可检验的替代方案。该模型将引力而非奇异场视为宇宙演化的核心驱动力，其观测效应将突破当前的观测视界限制。
