Scientists have unveiled an unprecedented map of all the matter in the universe using two very different telescopes, an effort that revealed weird inconsistencies between our observations and models of the so-called “cosmic web” that links the cosmos, according to new research. 

The results suggest that our universe appears to be slightly less “clumpy” than expected based on our best models, an anomaly that might be resolved by future precision measurements or could potentially point to deeper problems in our understanding of the cosmic web.
