Giant Structures

14 November 2019

In one of those, I wonder what they can be moments, we have another interesting link provided by Gary – https://www.vice.com/en_us/article/zmj76pw/theres-growing-evidence-that-… … scientists are discovering that galaxies can move with each other across vast distances – against the predictions of mainstream cosmological models. Some galaxies seem to move in odd and often unexplained ways as if they were connected by a common unseen force. These discoveries hint at an enigmatic influence – what are being called large scale structures in space. These are theorised to be made of hydrogen gas and dark matter and take the form of filaments, sheets, and knots that link galaxies in a network that is now known as the cosmic web. They appear to constrain the laws of gravity and the nature of dark matter is one of the imponderables – and these phenomena seem to challenge the fundamental ideas of mainstream about the universe.

A study published in the Astrophysical Journal in October (2019) found that hundreds of galaxies were rotating in sync with the motions of galaxies that were tens of millions of light years away. The secret, whatever it is, behind these synchronised galaxies, may pose a threat to the cosmological principle. It is unclear if the threat to that is more disturbing than the fact galaxies move in sync but they continue by saying this principle is one of the basic assumptions about the universe. The principle states that the universe is basically uniform and homogenous at extremely large scales.

Another problem are the satellite galaxies which are mostly aligned around larger galaxies such as the Milky Way. They are a thorn in the side of mainstream models we are told and the theoretical timeline of the universe, since Big Bang. The problem is they are not situated randomly but are synchronised into one tidy orbital plane.

Over at https://phys.org/news/2019-11-runaway-star-galactic-heart-darkness.html … we have a star moving ten times faster than other stars in the Milky Way. It is somewhere near the centre or heart of the Milky Way, we are told, and not far from the hypothetical black hole lurking there. As one might suspect astronomers are getting very excited as it could be that the black hole is in some way ejecting the star (zipping it).
