Mystery Atlas"Dark Flow" Claim
A 2008 claim of coherent galaxy-cluster motion potentially extending toward or beyond the observable universe's edge; frequently confused with the Great Attractor in popular coverage but far more speculative, and not confirmed by later, more sensitive data including Planck satellite analyses.

Theories & Explanations
"Dark Flow" Claim contradicts Great Attractor Mass-Concentration Explanation — The well-measured, modest regional pull the Great Attractor explanation describes is a much better-supported claim than dark flow's unconfirmed universe-scale motion.
Science & Technology
"Dark Flow" Claim is frequently compared to Dark Energy — Both are large-scale cosmological claims at the edge of current observational confirmation, though dark energy has far stronger, independently replicated evidentiary support.
"Dark Flow" Claim is frequently confused with Great Attractor — Popular coverage routinely conflates the two, though dark flow is a separate, far more speculative and unconfirmed universe-scale claim.
