We Are Moving Through The Universe Faster Than We Thought
- New measurements from radio galaxies indicate the Milky Way is moving faster than the CMB-based estimate.
- Both methods point in the same direction, but the radio galaxy result exceeds the CMB result by about 5.4 sigma.
- The finding challenges the standard cosmology model and could indicate gaps in our understanding of cosmic motion.
- Researchers used sky survey data of radio galaxies, which are bright at radio frequencies and visible across vast distances.
- The motion speed inferred from the CMB is about 360 km/s for our galaxy.
