Giant ropes of dark matter

Giant ropes of dark matter found in new sky survey is the title of New Scientist article describing the finding that dark matter seems to concentrate along string like filaments at the sky. The lengths of filaments are up to 270 million light years at least. Note that the size scale of large voids containing galaxies at their boundaries and known for long time to concentrate along stringy structures is same.

The finding is interpreted as a victory for models assuming that dark matter was originally evenly distributed but then gradually concentrated to form blobs and filaments. I do not know how much the formation of filaments is an input assumption rather than genuine prediction of these models.

In TGD framework the course of events would be just the opposite. The cosmic strings - not those of GUTs, but identified as string like objects of form X²×Y², where X² is minimal surface in M⁴ and Y² in the most general case is holomorphic surface of CP₂ - dominated the primordial stage of TGD inspired cosmology after which ordinary space-time with 4-D M⁴ projection emerged. These string like objects carried extremely strong magnetic fields and also dark matter, which can be also ordinary matter but in large hbar phase.

The M⁴ projections of cosmic strings became 4-dimensional and begun to thicken with the cosmic expansion. The magnetic field within them weakened gradually. The model explains also the magnetic fields which fill the cosmos but whose origin is one of the mysteries of the standard cosmology. Note that in GUTs long cosmic strings would remain as such and this leads to problems since they have not been observed.

In TGD Universe this kind of magnetic flux tubes carrying dark matter appear even in living matter and are responsible for the quantum control of visible part of living system. The braids formed by magnetic flux tubes make DNA-cell membrane system topological quantum computer. The very strange findings about the behavior of cell membrane provide direct support for the prediction that a large fraction of biologically important ions are dark and possess large hbar. Note that in TGD framework also dark energy is dark matter and no cosmological constant is needed. The explanation for the periods of the accelerated cosmic expansion is in terms of phase transitions increasing the value of Planck constant.

I add an excerpt from a New Scientist article about cosmic strings.

Discovering them would be really big news. String theory has often been criticised as a theorists’ plaything, a pretty piece of mathematics unable to make any testable predictions. That perception would change pretty fast if we were to find a host of giant superstrings crisscrossing the skies.

Just this has been now done. But not for superstrings. So they decide to forget it once again. I hope that reader could sense some of my despair. More than two decades of attempts to open the eyes of colleagues to see the reality which is staring directly to their empty eyes and doing all it can to gain their attention. All in vain. You know: "We-know".

A further comment added: In Cosmic Variance there are comments about the recent very stringent experimental limits on the properties of WIMPs (weakly interacting massive particles). Perhaps the time is becoming ripe for challening various routine assumptions about dark matter.

1. The first standard assumption is that dark matter has no classical long range interactions with the visible matter except gravitation. Experimental tests are however in astrophysical scales and do not tell anything about possible classical electromagnetic interactions.

2. The second implicit assumption is that if the interactions of dark and visible matter via classical fields are possible then both dark and visible particles can appear in the same vertex of Feynman diagram. In TGD framework the generalization of the motion of imbedding space however implies that particles in different sectors of imbedding space cannot appear in the same vertex of Feynman diagram. Interactions via all classical fields are however possible and also the exchange of quanta leaking between different sectors of the 8-D imbedding space (visible-dark phase transition for exchanged particles). This picture of course requires a considerable generalization of quantum theory by introducing the hierarchy of Planck constants and bringing in anyons at the level of fundamental physics.
