Abstract
In this paper, we build up a scaled homology theory, -homology, for metric spaces such that every metric space can be visually regarded as "locally contractible" with this newly-built homology. We check that -homology satisfies all Eilenberg-Steenrod axioms except exactness axiom whereas its corresponding -cohomology satisfies all axioms for cohomology. This homology can relax the smooth manifold restrictions on the compact metric space such that the entropy conjecture will hold for the first -homology group.
