About Chang-sik Kim

I am an independent researcher based in the Republic of Korea and the first proposer of the Effective Viscoelastic Spacetime (EVM) framework. My research focuses on theoretical physics, cosmology, and astrophysics, specifically addressing the dynamic behavior of galaxies.

Through the EVM framework, I explore how the delayed macroscopic response of spacetime—governed by a cosmologically related relaxation timescale—can naturally explain galactic dynamics, such as flat rotation curves and the radial acceleration relation (RAR), without invoking dark matter.

Intro Content

Introducing the Effective Viscoelastic Spacetime Model: A New Paradigm for Galaxy Dynamics and R A R

The dynamics of disk galaxies exhibit a striking regularity that challenges the standard paradigm. I introduce an effective viscoelastic spacetime framework where a delayed gravitational response naturally reproduces the radial acceleration relation and flat rotation curves.

I welcome any questions, constructive feedback, or open discussions regarding the Effective Viscoelastic Model (EVM) framework and its approach to galactic dynamics.
