I will take your non- answer to be what it is, evidence of your delusional denial state of existence. 'Hubble Finds Ghostly Ring of Dark Matter' http://www.nasa.gov/mission_pages/hubble/news/dark_matter_ring_feature.html "Astronomers using NASAs Hubble Space Telescope got a first-hand view of how dark matter behaves during a titanic collision between two galaxy clusters. The wreck created a ripple of dark matter, which is somewhat similar to a ripple formed in a pond when a rock hits the water." The ripple will eventually reach the Earth and this is evidence dark matter exists from the galaxy cluster to the Earth. This is evidence dark matter is the medium of space in which light waves propagate. Pressure exerted towards matter by dark matter displaced by the matter is gravity.

I used to drink Ripple occasionally. I'm quite sure it all returned to earth eventually.
