Astronomers in the first week of January 2013 discovered the largest known structure in the Universe called Large Quasar Group (LQG) that is powered by super massive black holes clump together. This cluster of galaxies spans across four billion light years.
Quasars are considered to be the nuclei of galaxies of the universe, which undergoes brief period of extremely high brightness making them visible in the sky from extreme distant positions.
The LQG was identified by a research team from the University of Central Lancashire (UCLan) that is led by Dr. Roger Clowes and the significant size of the same is challenging the Albert Einstein’s Principle of Cosmology. The principle states – the Universe when viewed at a large scale, it seems to be the same; it doesn’t matters that from where it is being observed from. The Einstein’s principle is just an assumption but was never demonstrated after observations so it’s beyond reasonable doubts.
The newly, discovered LQG carries a dimension of 500 megaparsecs (Mpc). The elongated structure makes its longest dimension to a size of 1200 Mpc or 4 billion light years, which is 1600 times larger than the distance between the Milky Way Galaxy and the Andromeda Galaxy.
Andromeda Galaxy is the nearest neighbour of the Milky Way Galaxy and is separated from each-other by about 0.75 Mpc or 2.5 million light years. The cluster of whole galaxies of the Universe can be up to 2 to 3 Mpc and the LQGs can go up to 200 Mpc and above. The modern calculations of astrophysicist’s states that they can’t find any structure larger than 370 Mpc and these calculations are made on the basis of modern theory of cosmology and the principle of cosmology. One will take 4 billion years to cross the LQG if one travels with the speed of light and this is just not because of its huge size but also because it has challenged the accepted principle of cosmology given by Einstein.
