Causal Memory Gravity I: Cosmological Baseline and Reduced Almost-Λ Dynamics

Key Points

• The aim is to establish a new framework of gravity that incorporates spacetime memory for cosmological applications.
• Developed the effective field theory of Causal Memory Gravity.
• Analyzed predictions against observations of cosmic expansion, large-scale structure, and supernova distances.
• Checked mathematical consistency of the proposed theory.
• A single memory sector explains critical cosmological data effectively.
• Achieved consistent outcomes without needing particle dark matter.
• Provided foundational support for ongoing research in Causal Memory Gravity.
