Hi Jarrick:). I saw your edit on the Universe talk page.

When talking about "ordinary matter" (as opposed to Dark Matter or Dark Energy), physicists lump everything we know about in that category. So neutrinos, gas, planets, stars, black holes, brown dwarfs, and every type of random particle that they've positively identified is included in "matter". In short, "matter" means "everything we've discovered". Dark Matter is anything we haven't discovered that interacts gravitationally with regular matter. Dark Energy is... whatever it is:P. They're not entirely sure, but there seems to be a lot of it. Dark Matter might be comprised of many different types of stuff, and we might just be seeing the aggregate effect of everything we can't currently detect. Ditto for Dark Energy. Both those terms are merely placeholders, and will be replaced when they're fully identified.

Eventually, at some distant point in the future, it won't be "4.whatever percent matter, 20some percent dark matter, etc. It will be something like "1 percent neutrinos, 1 percent Dark Matter Type Y, 3 percent baryons, 4 percent Dark Matter Type A... etc. We just haven't discovered what those type(s) of Dark Matter are yet. &mdash; Gopher65talk 00:04, 13 October 2014 (UTC)
