Resonant Spacetime Hypothesis 2.0

CHAPTER 1. Introduction

Motivation: Tensions in CDM and Limits of Inflation  

The CDM model, while successful in explaining cosmic expansion and large-scale structure (LSS), faces mounting tensions from high-precision observations:  

1. JWST's High-z Galaxies  

   - Galaxies at z > 10 (e.g., JADES-GS-z13-0) exhibit stellar masses (M 10 M) and metallicity levels inconsistent with CDM's hierarchical assembly timescales.  

   - Problem: CDM predicts 500 Myr are needed to form such galaxies, yet they appear <300 Myr after the Big Bang.  

2. CMB Anomalies

   - Low- Multipole Alignments: Quadrupole-octopole planarity ("Axis of Evil") has a <1% probability in Gaussian random fields.  

   - Power Suppression: Lack of correlation at > 60, unexplained by inflation.  

3. Inflation's Fine-Tuning  

   - The inflaton potential V() requires ad-hoc tuning to match CMB fluctuations (A 210).
