Still pretty sketchy on the details, as it states that the amount of matter existing is only double of what has been observed, so I am led to believe that maybe this is not meant to include non-baryonic matter, if that is even a valid hypothesis now.

 

Filaments that are a million degrees celsius.

Here's the preprint. http://arxiv.org/abs/1104.0711

I recently read an interesting article in New Scientist which outlined a recent study suggesting that much of the 'missing' mass of the Universe might be found in huge clouds of ultra-cool hydrogen detected throughout scattered part of the cosmos.

Being so cool, these clouds of hydrogen are very compact, and hence have quite a high mass density. They are said to range anywhere up to the scale of the Solar System, and emit a 'steady glow' of radio-wave length energy streams.

 

However, even if this were to be found true, at least 1/3 of the postulated Universe 'mass' would still be missing...

Is the headline misleading? It makes it sound like they figured out dark matter. It says nothing about "non-baryonic" matter. They only explained missing regular (not dark) matter.

 

This is a comment below the story by Steve Nerlich.

 

"I think the deal is that this study confirms Bregman's prediction outlined here: http://arxiv.org/PS_cache/arxi...

 

The universe recipe of 74% dark energy, 22% dark matter and 4% baryonic is unchanged. It's just that Bregman predicted that a lot of the baryonic matter would be in the form of Warm-Hot Intergalactic Medium (WHIM) - or filaments. This appears to be confirmed now, so good science all round.

 

I'm not sure what the link with Zwicky is - who is not obviously cited in either the Fraser-McKelvie or Bregman papers, but might have missed something."
