Unexpected cosmic clumping could disprove our best understanding of the universe

A survey of more than 25 million galaxies has found a strange contradiction in how astronomers measure the universe’s clumpiness, and it could threaten the standard model of cosmology, which describes how the universe formed and evolved.

The discrepancy, found by measuring the warping of light by the powerful gravitational fields of distant galaxies, suggests that the cosmos is less packed-together than previously predicted.
