Dark matter space superstructures observed for first time

Russia TV, 05 July, 2012, 16:48

Scientists have for the first time directly observed dark matter, which forms the greatest part of a galactic filament, the largest-known structure in the universe.

­On the largest scale the universe looks like an intricate web. Clusters of galaxies, which form its strands, are connected by much slimmer bridges, or filaments, with huge voids in between.

The shape of these structures is determined by distribution of dark matter, which cannot absorb or emit electromagnetic radiation and thus cannot be seen in a conventional way. But dark matter is estimated to be almost five times as common in the universe as regular matter, and its gravitational pull has clumped galaxies into what they are today.

Detecting dark matter is possible thanks to gravitational lensing – the bending of light from distant galaxies as it travels through and next to it due to the wrap of space caused by gravity. That is relatively simple to do with the dark matter in the nodes of the space web, but the filaments are too narrow cosmically speaking.

Now an international team of astrophysicists has discovered a dark matter filament, which stretches in a very convenient way for observation. It connects the galaxy clusters Abell 222 and Abell 223. The filament is oriented in a way that most of its mass lies along the line of sight to earth. So the lensing effect it produces on the light we can observe is greatly enhanced, the group reported online on Wednesday in the Nature journal. It is still too weak to be seen by eye, but could be determined statistically.

"The standard wisdom is that the gravitational lensing of filaments is too weak to be detected with current telescopes," Jörg Dietrich, a cosmologist at the University Observatory Munich in Germanyt who co-authored the study, told "Only when we realized this system has such a peculiar geometry did we realize we have a chance."

The scientists studied distortion of more than 40,000 background galaxies and calculated the mass and shape of the filament, a feat no astronomers had previously managed to pull off.

Researchers used data from the Subaru telescope on Mauna Kea in Hawaii and the XMM-Newton space telescope. They also used a model to subtract out the masses of the galaxy clusters. The remaining mass is attributed to the filament.



I wonder if dark matter could be touched and felt? If there was a lump of invisible dark matter on my kitchen table, if I reached out my hand, could I feel it, even though I couldn't see it?

The answer is NO. If Dark Matter is compressed into third density, then you can feel it and see it as well. But if Dark Matter energy is compressed in the 5th or higher density, you can neither see it not touch it. It will travel through you without feeling anything.


Existence in the 5th density or higher, is protected vibrationally by lower density existence and it is impossible to inflict harm to 5th density by those of lower ones. If you want to know who is in the 3rd density, I would tell you everything you can see around you and up in the cosmos. All the planets, stars, galaxies, universe, they all exist in the 3rd density.
