A Covariant Viscoelastic Spacetime Origin of the Galactic Acceleration Relation

Key Points

To propose a viscoelastic spacetime theory that accounts for galactic acceleration phenomena.
Developed a covariant viscoelastic spacetime model
Identified a characteristic acceleration scale
Analyzed data from the SPARC galaxy database
Predicted acceleration scale aligns with observed radial acceleration relation
Explained flat galaxy rotation curves
Provided a framework for the baryonic Tully–Fisher relation

Abstract

This work proposes a covariant viscoelastic spacetime frameworkin which spacetime possesses a finite relaxation time determinedby cosmological expansion. The theory predicts a characteristic acceleration scale aₘem = κ c H0 / (2π) which naturally explains the radial acceleration relation (RAR), flat galaxy rotation curves, and the baryonic Tully–Fisher relation. The model is tested using the SPARC galaxy database.
