VIRTUAL UNIVERSE In a snapshot from the Illustris computer simulation of the universe, galaxies (pink) cluster along filaments of dark matter (blue).

In their simulations, Gao and Theuns found that within clumps of cold dark matter, single massive stars formed, but warm dark matter formed filaments about a quarter the width of the Milky Way, attracting enough ordinary matter to create some 10 million stars — and some of these very first stars could still be around.

Partially dimmed x-rays (dips in graph) from a flaring blazar (right) reveal two filaments of hot, diffuse matter in the vast spaces between galaxies.

According to theory, the bulk of the matter in the universe consists of large, dark filaments of gas in the vast empty space between galaxy clusters.

This simulation of the early universe shows matter arranged in filaments; a new observation supports this model.

The observation supports a popular theory of cosmic evolution in which matter first collected into a network of thin filaments and later coalesced into clusters and superclusters.

In October a team led by Mathilde Jauzac at the Laboratoire d'Astrophysique de Marseille in France created a 3 - D representation of an enormous filament of dark matter, the invisible substance that fills our universe and binds galaxies togetheIn October a team led by Mathilde Jauzac at the Laboratoire d'Astrophysique de Marseille in France created a 3 - D representation of an enormous filament of dark matter, the invisible substance that fills our universe and binds galaxies togethein France created a 3 - D representation of an enormous filament of dark matter, the invisible substance that fills our universe and binds galaxies together.

It holds that in the earliest days after the big bang, exotic dark matter, with just a sprinkling of normal matter, clumped into blobs along narrow filaments.

That discovery means theorists have been right about the role of filaments in funneling matter in the visible universe.

During its journey to Earth, the light from these faint galaxies must pass through the lumps and filaments of dark matter in the cosmic web.

If so, instead of clumping, the researchers report in tomorrow's issue of Science, this warm dark matter would have stretched into filaments thousands of light - years long and weighing as much as millions of suns.

The structure of the cosmos is Swiss cheese - like in the sense that it is composed of «normal matter» in the form of voids and filaments.

Tanimura's group found they were almost three times denser than the mean for normal matter in the universe, and de Graaf's group found they were six times denser — confirmation that the gas in these areas is dense enough to form filaments.

The young galaxies seem to reside at the junction of gigantic filaments in a web of dark matter.

Because galaxies are pulled toward gravitational attractors and move away from empty regions, these motions allowed the team to locate the denser matter in clusters and filaments and the absence of matter in regions called voids.

In this case, the researchers looked for distortions to light being emitted by background galaxies caused by foreground dark matter filaments.

Dark matter resides in the halos around those galaxies, and was also known to spread from those denser areas in filaments.

In their paper, Hudson and Epps list dozens of previous studies that have attempted to measure and observe the dark matter web, and they say they hope their stacking techniques to measure the filaments between groups and clusters of galaxies can serve as a foundation for future filament studies.

Dark matter filaments bridge the space between galaxies in this false colour map.

The locations of bright galaxies are shown by the white regions and the presence of a dark matter filament bridging the galaxies is shown in red.

The rest of the ordinary matter is probably hiding in long strands, or filaments, of gas.

For gravity to clump galaxies together into walls or filaments, there must be large amounts of mass left over from the big bang, particularly unseen mass in the form of dark matter.

Scientists have decoded faint distortions in the patterns of the universe's earliest light to map huge tubelike structures invisible to our eyes - known as filaments - that serve as superhighways for delivering matter to dense hubs such as galaxy clusters.

These filaments, spanning across millions of light - years — much larger than the largest galaxies — constitute the cosmic web, and account for most of the ordinary matter (as opposed to dark matter) in the universe.

The first map of dark matter in a major part of the universe shows that clusters of galaxies form at the increasingly clumpy intersections of dark matter filaments over time (more).
