Recently the discovery of largest known structure in the universe is claimed, is more than a gigantic curiosity.
The discovery of huge Large Quasor Group (LQG) was announced last week by multinational astronomer's group led byDr. Roger Cloves of the University of Central Lancashire other member of the team included Kathryn Harris, Luis E. Campusano (Universidad de Chile),Srinivasan Raghunathan, , Ilona K. Sochting (University of Oxford) and Matthew J. Graham ( California Institute of Technology).
LQG is 4 billion light years in length means light would require time of 4 billion years to travel from its one end to another. that is nearly one-twentieth the diameter of whole Universe, one of the most surprising news arising several questions. Team used Solan Digital Sky Survey, most comprehensive 3D map of the universe.
One of the main reasons that that discovery sets ripples around the cosmologist as it arises doubt on some Einsteins relevant concepts. Till the discovery of the Huge-LGQ, it was assumed that the upper limit of size for cosmic structures was somewhere around one billion light years. The recent discovered LQG is four times larger than the the expected upper limit of universe, which shaken the science of the universe.
The largest structure in the universe was recorded as 1.38 million light years form one outer end of galaxy to other, named Solan Great Wall. However it some scientist also suggests that Solan great wall is the cluster of three different galaxies clinged together.
However it's a question of debate that LQG is single or the combination of more. There is so much more to be reveled , It is a one more step forward to the discovery of universe.
