Perhaps I am being too simplistic, but wouldn't this imply that dark
matter existed beyond our light cone? If dark matter only exists
beyond our light cone we could expect to see gravitational effects at
the edge of our visible universe affecting galaxies near the edge.
Whereas research seems to indicate that dark matter permeates our
visible universe and is clustered around our galaxies. We can even map
the areas where dark matter must be.
