The structure of a galaxy 1.3 billion light-years in diameter contradicts what we know about the universe.
Galactic structure could reimagine an ancient cosmological principle. Scientists study it to determine changes.
A few days ago, from January 7 to 11, the 243rd meeting took place American Astronomical Society in New Orleans (USA). The event featured several discoveries made in recent months and some projects currently underway. Among what we saw, we had observations galaxy structure, ring-shapedwhose proportions defy what we know about Universe.
The point is that this space megastructure Has a diameter of approx. 1.3 billion light yearswhich already does this at the beginning one of the largest galactic formations ever observed. It is worth saying that his observations turned out to be a real feat, since the ring is more than 9 billion light years from Earth.
Challenging the Famous
This impressive structure, due to its size, challenges a fundamental assumption called cosmological principle. According to this, starting from a certain spatial scale, The universe is homogeneous and the same in all directions..

It happens that he Big Ringsince the structure in question is called, does not correspond to this cosmological principle. This question has puzzled scientists, but this is not the first time they have encountered something like this. There is another formation called “Giant Arch” which includes 3 thousand 300 million light years. Both, curiously, are located at the same distance from the Earth, so there is a possibility that they constitute the same cosmological system.

He Big Ring was discovered through data analysis Sloan Digital Sky Survey (SDSS)), catalog of distant quasars. It is still unknown what mechanisms could cause this. And although this contradicts what is known, scientists say that It is natural to abandon old principles in the face of new discoveries..
