Yoshiki Ashida
INDEPENDENT RESEARCHER — COSMOLOGY
Born in 1948.
During my active career, I was involved in media development at Dentsu Incorporated, Mitsubishi Corporation, and Waseda University.
After retirement, I am working as a Pole Dancer, Digital Artist, Poet, and Astrophysicist.
Second paragraph placeholder for research interests and current activities.
I am a self-taught astrophysicist.
Until now, I have never received formal higher education in astrophysics.
Even now, I do not belong to any specialized research institution related to astrophysics.
I continue my research in astrophysics purely out of personal interest.
My research methods are not empirical but purely theoretical. Instead of empirical experiments, I use thought experiments to tackle the mysteries of the universe.
In other words, my research style is to construct hypotheses that can be explained without contradictions by interpreting the given data theoretically.
Despite this, I strive to build an accurate universe model by fully utilizing the valuable data collected by predecessors through practical experiments without falling into mere theoretical speculation.

INTRODUCTION
A Geometric Cosmological Model Explaining Internal Isotropy Within a Finite Universe
This manuscript introduces the Escher Model, a new static, non-homogeneous cosmological framework designed to resolve a long-standing paradox in cosmology: how a universe that appears finite and asymmetric from an external viewpoint can be experienced as infinite and isotropic by observers inside it.

ARTICLE
Geostationary Cosmology Based on Escher's Space Drawings
The Escher Model proposes a static, finite, spherical universe that explains Hubble's redshift without cosmic expansion. It suggests that gravitational time dilation, caused by increasing mass density toward the universe's outer boundary, produces the observed redshift.

APPENDIX
Mathematical Definition of the Escher Model: A Static Non-Homogeneous Cosmological Framework
The model further demonstrates that geometric invariance continuously re-centers each observer's local coordinate system, causing every observer to perceive an infinite, isotropic universe despite the universe being finite from an external perspective.
