Dark Matter Waves at the Center of Galaxies --"The 'Operating System' of the Universe"

Is dark matter the "operating system" of the Universe? Tom Broadhurst, an Ikerbasque researcher at the UPV/EHU's Department of Theoretical Physics, thinks it is. He has participated alongside scientists of the National Taiwan University in a piece of research that explores cold dark matter in depth and proposes new answers about the formation of galaxies and the structure of the Universe. This theory can be used to suggest that all the galaxies in this context should have at their center large stationary waves of dark matter called solitons, which would explain the puzzling cores observed in common dwarf galaxies.

In cosmology, cold dark matter is a form of matter the particles of which move slowly in comparison with light, and interact weakly with electromagnetic radiation. It is estimated that only a minute fraction of the matter in the Universe is baryonic matter, which forms stars, planets and living organisms. The rest, comprising over 80%, is dark matter and energy.

The theory of cold dark matter helps to explain how the universe evolved from its initial state to the current distribution of galaxies and clusters, the structure of the Universe on a large scale. In any case, the theory was unable to satisfactorily explain certain observations, but the new research by Broadhurst and his colleagues sheds new light in this respect.

As the Ikerbasque researcher explained, "guided by the initial simulations of the formation of galaxies in this context, we have reinterpreted cold dark matter as a Bose-Einstein condensate". So, "the ultra-light bosons forming the condensate share the same quantum wave function, so disturbance patterns are formed on astronomic scales in the form of large-scale waves".

The image above is a comparison of the radial density profiles of the galaxies which the researchers have created by displaying the soliton in the centre of each galaxy with a halo surrounding it. The solitons are broader but have less mass in the smaller galaxies.

The image left, below, shows that a comparison of the distribution of matter is very similar on a large scale between wave dark matter, the focus of this research, and the usual dark matter particle.

Image right shows that in galaxies the structure is very different in the interpretation of the wave, which has been carried out in this research; the research predicts the soliton of dark matter in the centre surrounded by an extensive halo of dark matter in the form of large "spots", which are the slowly fluctuating density waves. This leads to many predictions and solves the problem of puzzling cores in smaller galaxies.

The research also makes it possible to predict that galaxies are formed relatively late in this context in comparison with the interpretation of standard particles of cold dark matter. The team is comparing these new predictions with observations by the Hubble space telescope.

The results are very promising as they open up the possibility that dark matter could be regarded as a very cold quantum fluid that governs the formation of the structure across the whole Universe.

This is not Thomas Broadhurst's first publication in the prestigious journal Nature. In 2012, he participated in a piece of research on a galaxy of the epoch of the reionization, a stage in the early universe not explored previously and which could be the oldest galaxy discovered. This research opened up fresh possibilities to conduct research into the first galaxies to emerge after the Big Bang.

Tom Broadhurst has a PhD in Physics from the University of Durham (United Kingdom). In 2010, he was recruited by Ikerbasque and carries out his work in the UPV/EHU's department of Theoretical Physics. His line of research focuses on observational cosmology, dark matter and the formation of galaxies.

In a discovery announced Jan. 18, 2012 a team of researchers including an MIT postdoc has found a dark dwarf galaxy about 10 billion light years from Earth. It is only the second such galaxy ever observed outside our local region of the universe, and is by far the most distant. The dwarf galaxy is a satellite, meaning it clings to the edges of a larger galaxy. “For several reasons, it didn’t manage to form many or any stars, and therefore it stayed dark,” says Simona Vegetti, a Pappalardo Fellow in MIT’s Department of Physics.

It's dark mass, not dark matter.

Physicists are starting to realize the notions of dark matter and the dark matter particle are incorrect. They are referring to the mass which fills 'empty' space as the 'dark mass' in order to distinguish it from the baggage associated with dark matter.

"That is, all that we are certain about [is] the dark mass, not dark matter, let alone to say about the dark 'particle'."

Particles of matter move through and displace the dark mass, including 'particles' as large as galaxies and galaxy clusters.

The Milky Way moves through and curves spacetime.

The Milky Way moves through and displaces the dark mass.

The state of displacement of the dark mass is curved spacetime.

@mpc,there is no such thing called curved space or dark mass.there are no set parameters in relation to the universe..the map you are always shown of the universe is only designed for a coherent observation.and when it comes to dark mass ?,whatever that is.the only thing it can be is plasma or electromagnetic plasma.our universe is 99.9% of this and always has been,but for some unknown reason this has never been taught in schools and you will not find any books which includes this phenomena.electromagnetic plasma is 39 thousand billion,billion,billion,billion times more powerful than gravity,just because you cannot see it does not mean it does not exist.it is just the same as the power that goes into your home.this same force creates all galaxies without initially resorting to the forces of gravity.it only when it cools does gravityvtake affect.

I prefer to call it shy matter. The seven states of matter - solid, liquid, gas, plasma, consciousness, BBQ and shy.

Conclusion was already reached and reported by Anne Astronomy News. These guys are getting real close to stealing reported information.
