I stumbled across an interesting article while searching for a source in something else I was working on. This article, "How the Universe Will End" (http://zyx.org/HOAX3.htm#dark%20matter), purportedly represented from Time magazine, mentions "dark matter" (just before the section "Echo of the Big Bang"), saying, That thought just blew me away when I thought of it, "we aren't even made of the same stuff the universe is"!

So I got to thinking, since a notion from a few decades back is that the 'dark matter' was simply cold, as opposed to those beautifully hot, nebulosities that Hubble and other big telescopes make those fascinating pictures of, or the rocky matter of asteroids, comets, and meteors--things like what we'd find in the Kuiper belt or Oort cloud.

Since we use benchmark star and clusters of other galaxies to infer things like distance and rotation, is there not any "normal matter" data of consequence in the spectrum from places like Andromeda that indicate the chemistry of intergalactic space, where the dark matter lurks? Is there not something that tells us 'dark matter' is not just another Magellanic Cloud or Coal Sack cold nebulosity?
