The Largest Galaxy Clusters in the Universe Hint That Something is Behaving Strangely

Galaxy Cluster LCDCS-0829Via the Daily Galaxy:

The large-scale structure of the Universe appears to be dominated by vast “hyperclusters” of galaxies, according to the new the Sloan Digital Sky Survey, compiled with a telescope at Apache Point, New Mexico. The survey plots the 2D positions of galaxies across a quarter of the sky. The science team has concluded that it could mean that gravity or dark energy — or something completely unknown — is behaving very strangely.

We know that the universe was smooth just after its birth. Measurements of the cosmic microwave background radiation (CMB), the light emitted 370,000 light years after the big bang, reveal only very slight variations in density from place to place. Gravity then took hold and amplified these variations into today’s galaxies and galaxy clusters, which in turn are arranged into big strings and knots called superclusters, with relatively empty voids in between.

On even larger scales, though, cosmological models say that the expansion of the universe should trump the clumping effect of gravity. That means there should be very little structure on scales larger than a few hundred million light years across.

    Someone needs to tell God his gravy is getting a bit lumpy.

    There’s probably just some unspeakable Lovecraftian horror out there. If you stop and think about it, you’ll probably go insane.

    Cosmology is a pointless circle jerk.

    Unless you like soggy, salty crackers.

    They don’t know what the fuck is going on is all. The incredible strides physics, astronomy, cosmology have made, made ’em think they’re more knowledgeable than what they are.
