Galaxy Expansion

FULL COLOR. 28 pages. Extract on Galaxy Expansion from book Relatively Simple, 2nd Edition. This extract from Relatively Simple gives a taste of the book's scope. The chapter on Galaxy expansion is extended as an appendix which evaluates the expansion mechanism. There is an indication that acceleration of the expansion is self-limiting with visible matter. Dark matter may exist but acceptance of dynamic expanding galaxies greatly reduces the need for large quantities of dark matter within them.
