Unprecedentedly wide and sharp dark matter map
I&#x27;m confused.  This article says it&#x27;s about a dark matter map, but it spends most of its time talking about accelerated expansion, the cause of which is labeled dark <i>energy</i>, not dark matter.  Dark matter (I am given to understand -- IANACosmologist) acts on a much smaller scale to hold galaxies together which would come apart under the gravitational influence of visible matter alone.  What am I missing?
