Abstract

The Decreasing Universe (D.U.) theory proposes that the gravitational field induces a continuous contraction of space, offering an alternative explanation for cosmological redshift.1 A crucial and logical deduction from this theory is that a galaxy’s time of exposure to the gravitational field, i.e., its age, should directly influence the observed redshift. Older galaxies, having accumulated more time under spatial contraction, should exhibit a smaller redshift. This article examines this prediction, using the observed redshift difference between old (elliptical) and young (spiral) galaxies in clusters as a primary observational test for the D.U. theory.
