Giant Galaxy Arc: A 3.3 billion light-year galaxies seen in one arc, will the old theories on the universe change?


A unique ‘shape’ has been discovered 9.2 billion light-years away from Earth. A massive galaxy-arc spanning 3.3 billion light-years has been found in the Bootes the Herdsman constellation. With its discovery, the discussion has intensified about what is the view of space in general? This massive arc is 1/15th of the radius of the observable universe. Matter in the universe is believed to be spread out in a pattern. Therefore, it is expected that there will not be much irregularity when viewed on a large scale.

Arc
is three times bigger

The discovery was made by Alexia Lopez, PhD student at the University of Central Lincolnshire’s Jeremiah Horrocks Institute and advisor Roger Close, along with Gerard Williser of the University of Louisville, using the Sloan Digital Sky Survey. “Usually, a shape that is at least 1.2 billion light-years large is considered a limit,” Alexia said. So this huge arc is three times as big.’ In such a situation, the question arises whether such a huge figure is a coincidence or is the truth more than that? (ALEXIA M. LOPEZ/Jeremiah Horrock)

How did you study?

Regarding the universe, it is believed that whatever part of it can be seen, the rest will be the same. This is called the Cosmological Principle. The huge arch and other such figures raise questions on this. For this, the researchers studied the effect of quasars on the magnesium absorption system. Quasars are distant galaxies that emit large amounts of energy and light. Alexia says that the quasar acts like a giant lamp. He has told that the spectra made from these quasars can be studied with the help of telescope.

How is the universe?

This shows where the light was absorbed. With the help of magnesium, it can be detected that quasar light has passed through galaxies. With the help of this ‘fingerprint’, such matter can be seen which usually does not shine much. Alexia said that when viewed on a large scale, it is expected that the matter will be spread in a way. According to this, the pattern seen in a vast part, the whole universe will be filled with the same pattern, no matter which part is seen from anywhere. However, the finding of the giant arc has raised the question of what is the extent of this pattern.
