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.

To put that mind-boggling size into perspective, the disk of the Milky Way galaxy — home of Earth's solar system — is about 100,000 light-years wide. And the Milky Way is separated from its nearest galactic neighbor, Andromeda, by about 2.5 million light-years.

i never could grasp astrology.

the distance is mind boggling.

all i gathered is, this thing is like a fucking golf club and we are the ball.

A controversial claim by Laura Mersini-Houghton is that it could be the imprint of another universe beyond our own, caused by quantum entanglement between universes before they were separated by cosmic inflation.[14] Laura Mersini-Houghton said, "Standard cosmology cannot explain such a giant cosmic hole" and made the remarkable hypothesis that the WMAP cold spot is "… the unmistakable imprint of another universe beyond the edge of our own." If true this provides the first empirical evidence for a parallel universe (though theoretical models of parallel universes existed previously). It would also support string theory[citation needed]. The team claims there are testable consequences for its theory. If the parallel universe theory is true there will be a similar void in the opposite hemisphere of the Celestial sphere[15][16] (which New Scientist reported to be the Southern hemisphere; the results of the New Mexico array study reported it as Northern hemisphere[17]).

A sophisticated method of data analysis - Kolmogorov complexity - has derived evidence for a north and a south cold spot in the satellite data:[18] "...among the high randomness regions is the southern non-Gaussian anomaly, the Cold Spot, with a stratification expected for the voids. Existence of its counterpart, a Northern Cold Spot with almost identical randomness properties among other low-temperature regions is revealed."

These predictions and others were made prior to the measurements (see Laura Mersini). However, apart from the Southern Cold Spot, the varied statistical methods in general fail to confirm each other regarding a Northern Cold Spot.[19] The 'K-map' used to detect the Northern Cold Spot was noted to have twice the measure of randomness measured in the standard model - the reason is speculated to be the randomness introduced by voids (unaccounted-for voids were speculated to be the reason for the increased randomness above the standard model).[20]

I do have a better one.  a phyisist predicted two great voids before they were discovered, based on the presence of a multiverse pushing into ours:

My human mind cannot even understand how big this structure is.

Even with a space shuttle we couldn't even see 0.0001% of it....

Wouldn't the biggest structure in the universe be the universe itself?
