Solar System Moving Faster Than Models Predict, Study Finds
The solar system's velocity is 3.7 times greater than predicted, challenging the Lambda-CDM cosmological model with a >5-sigma statistical significance, study finds.
On November 10, 2025, Physical Review Letters published a paper by Bielefeld University reporting the solar system moves more than three times faster than models predict, challenging standard cosmology.
Using LOFAR data, the team from Bielefeld University combined it with two additional radio observatories to map radio galaxies and applied a new statistical method producing larger yet realistic uncertainties.
The measurement shows a radio dipole 3.7 times stronger than predicted with a deviation exceeding five sigma and a subtle headwind effect from radio galaxies.
By contradicting standard cosmology, the findings force reconsideration of prior assumptions as co-author Dominik J. Schwarz says they question the cosmological principle or radio-source uniformity, testing the Standard Model of Cosmology .
In the coming years, upcoming LOFAR releases and the Square Kilometer Array may clarify if the anomaly is real or due to systematics, and a faster solar motion could imply faster galactic rotation.
