Astronomers from the University of Central Lancashire have discovered the largest known structure in the Universe called Large Quasar Group (LQG) that is powered by cluster of super massive black holes spanning across 4 billion light years.
What are Quasars?c
Quasars are believed to be the nuclei of galaxies of the universe, which undergoes short period of extremely high brightness making them visible in the sky from very distant positions.
The significant size of LQG is challenging the Albert Einstein’s Principle of Cosmology which states that 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. His principle is just an assumption but was never established after observations so it’s beyond reasonable doubts.
