Hubble Finds Missing Matter

Perhaps it's just the cosmology nerd in me, but I think this is very exciting stuff. The matter found was baryonic, but it highlights the cosmic web, which is highly interrelated with dark matter theory. I've always thought dark matter seemed like a bit of a sham, but this actually lends quite a bit of credence to it.

There's still a lot of baryonic matter that's unaccounted for, but I imagine this is going to be a very important discovery in the coming months and years.

(Mods, relocate this as appropriate)

Woah! thats pretty rad. when i first seen the title of this thread the first thing that popped into my mind was that they actually found dark matter, but thats not the case. still, it's very interesting. like you i had my doubts about the whole dark matter thing but this article is nudging me into a different direction.

i cant wait to see where this goes, they better get on those quasars.
its nice to see that those things arent just being used as a standard candles.

Another small step...

Unless somethings dramatically more pop out of this discovery, it still leaves a huge deficit of matter (or other "stuff") that can account for our observations, at least based on what we think we know.

I'm basing my comment on this part of the report: "...Baryons are protons, neutrons, and other subatomic particles that make up ordinary matter such as hydrogen, helium, and heavier elements. Baryonic matter forms stars, planets, moons, and even the interstellar gas and dust from which new stars are born.

Astronomers caution that the missing baryonic matter is not to be confused with "dark matter," a mysterious and exotic form of matter that is only detected via its gravitational pull..."

Nah this isn't nerdy.

I wonder if any of the scientists said: "so THAT'S where i left it". I would have.
