Huge Quasar Cluster is Largest Cosmic Structure

LGQ

What’s the biggest thing in the universe? That would be a cluster of quasars so large it would take a vehicle traveling at the speed of light 4 billion years to cross.

The structure, known as a Large Quasar Group, or LQG, is so massive scientists say it may challenge a fundamental principle of cosmology, laid out by Albert Einstein, which states that when viewed on a sufficiently large scale, the properties of the universe are the same for all observers.

“While it is difficult to fathom the scale of this LQG, we can say quite definitely it is the largest structure ever seen in the entire universe,” astronomer Roger Clowes, with the University of Central Lancashire, said in a statement.

    “Of particular importance is the sun’s extreme ultraviolet (EUV) radiation, which peaks during the years around solar maximum. Within the relatively narrow band of EUV wavelengths, the sun’s output varies not by a minuscule 0.1%, but by whopping factors of 10 or more. This can strongly affect the chemistry and thermal structure of the upper atmosphere.”

    Solar max is 2013. The sun kicked up today, but has been remarkably quiet recently. Yet there is an amazing amount of sunspots, … one that is really huge.

    Slightly off-topic. I was telling my brother yesterday that pot has always altered my spacetime perceptions, especially when I was riding my motorcycle while high on pot, in Hutchinson, Kansas.

    Researchers Compare Spacetime To A Smooth Whiskey
    According to new research led by Michigan Technological University, spacetime might be less like a foamy beer and more like a smooth Einsteinian whiskey.
