Solar System May Move Nearly 4 Times Faster as Radio Dipole Defies Standard Cosmology

Summary
New radio-galaxy analysis suggests the solar system could be moving nearly four times faster than estimates based on the cosmic microwave background.
Three surveys spanning 120 megahertz to 4 gigahertz produced a much stronger radio dipole after researchers regrouped multiple bright spots from complex radio galaxies into single sources.
That stronger-than-predicted signal leaves two main explanations: an unexpectedly high solar-system velocity or a universe whose matter distribution is less uniform on large scales than standard cosmology assumes.
Similar asymmetry has appeared in quasar data, and researchers say the Square Kilometre Array, due to start operating in 2027, should help separate local motion from cosmic structure.
