_thegeoff, 
#Cosmology folk: the universe as-is exists because the very early stages had density variations, stuff clumped. That's fairly obvious, the odds of the universe being perfectly evenly distributed are basically impossible, only one way to do it (and, quantum, not even allowed?)
So what's the thinking on how unlikely our "unclumpiness" is? Compared to...I don't know, perfect homogeneity versus weirdly clumpy?
ottaross, 
@_thegeoff Would be great to see a "You are here" icon on that scale, whatever it is.
ottaross, @robryk Good point – the macro and the micro, the observable world and the quantum scale. Large differences in the universe based on what yardstick you're using. @_thegeoff

🌌 Top Astronomers Gather to Confront Possibility They Were Very Wrong About the Universe | Futurism
「 The team found that one hemisphere actually hosted slightly more of these quasars, suggesting one area of the night sky was more massive than the other, undermining our conception of dark energy, a hypothetical form of energy used to explain why the universe is expanding at an accelerated rate 」

kazarnowicz, 
The Guardian had a good write-up about this, and I'm intrigued by two things:
One is the evidence that the universe isn't isotropic (iirc that's a 5 sigma study)The other is “evidence for cosmic flows – vast celestial rivers of material on a scale that cannot be readily accommodated within conventional theories”
