Aussie Student Finds Missing Mass

Anyone else see this?

What might this discovery do to dark matter theories?

[Cosmin]

I don't get it. What did she discover actually? I don't see any relation to dark matter which is about six times more prevalent than atomic matter.

I haven't heard of "Missing Mass".

Nothing.

The universe is thought to be composed of 74% dark energy, 22% dark matter, and 4% normal matter component. This new work is about the specifics of the 4% matter component. The first sentence from the abstract of the scientific research paper:

Most of the baryons in the Universe are thought to be contained within filaments of galaxies, but as yet, no single study has published the observed properties of a large sample of known filaments to determine typical physical characteristics such as temperature and electron density.

Examples of baryons include the protons and neutrons that make up most of the mass of normal matter. Dark matter is thought to be non-baryonic.
