The largest known structure in the universe has just been discovered, and is so large that it completely violates a number of widely-accepted theories. It’s a large quasar group (LQG), that’s so enormous that it would take someone traveling at the speed of light at least four billion years to completely pass through it.

Biggest Structure In The Universe Found, Large Quasar Group Of An Incredible Scale

Interesting article.

If true it's huge.

Astronomers have discovered the largest known structure in the universe, a clump of active galactic cores that stretches 4 billion light-years from end to end.

Very interesting story.

The author seems to think that it somehow topples Einstein because it seems to challenge the Cosmological Principle. It probably would make the Principle questionable if the Universe were only 14 billion light-years in radius but, thanks to hyper-inflation shortly after the big bang, it is a good deal larger than that.

Stand back far enough and I am fairly sure that the Principle will still hold: the universe will look roughly the same in any direction.

Pure mathematics is, in its way, the poetry of logical ideas.
