: : I would like to get some opinions on dark matter. Weather or not it exist, what its comprised of... etc. I tend to lean twords the theory that the Universe expands and contacts and seeing as that theory is not possible without some other type of matter to cause the colapse, im very insteresed in dark matter.

: the observational data from the rotation of galaxies clearly shows through cause and effect that some matter is at work to compensate for gravitational attraction i.e. the galixies do not fly apart under the forces of spin with oservable matter.Also the "sudsy" make up of our universe shows severe forces of gravity at work that are not explained with current physics which do not take into account the nessacery factors of matter.
