I was think about sending you these 2 studies that were published this month and which I saw yesterday. I was wondering if you had heard of them and what are your first impressions. Here's an article about them. Link to the studies are provided at the bottom of the article.

### [Astronomers Have Finally Found Most of The Universe's Missing Visible Matter](https://www.sciencealert.com/astronomers-finally-found-90-percent-of-the-universe-s-visible-matter)

Probably a better article about the subject. 

### [Half the universe’s missing matter has just been finally found](https://www.newscientist.com/article/2149742-half-the-universes-missing-matter-has-just-been-finally-found/)

Thanks a lot for the references. I hadn't read it before you mentioned them to me. I actually read the original articles that were available [**here**](https://arxiv.org/abs/1709.05024) and [**there**](https://arxiv.org/abs/1709.10378).

There are very nice studies. They actually confirm standard cosmology. In this context, 4-5% of the universe consists of normal matter. However, only half of that was observed today. The other half consists of filament of gas linking all the galaxies together (like a kind of web). These studies have measured independently the quantity of matter included in these filament, and the results agree with standard cosmology (still with very significant error bars).

Have I answered, or do you want more details?

I hadn't even realize the studies where talking about the visible 4-5%. 

My brain had mess up that part when I read. Thank you for clarifying that part and I feel privilege to be able to ask you questions about science. 

I won't ask many questions but from time to time I'll probably try to come up with good ones.

Please do ask question anytime! I am always happy to answer them. For instance, this question allowed me to learn something I didn't know, and I am thanking you for that ;)

Furthermore, I think that I will write one of my next posts (maybe the next one just to keep the momentum) about that topic. It is very interesting, and not that known ;)
