I've been reading Singh's Big Bang book, and towards the end he mentions that the CMBR was used to compute the relative speed of the Milky Way Galaxy, roughly 1,000,000 mph. This seems to suggest that the CMBR can be used as an absolute reference frame for any observer in the universe. However, relativity rejects the notion of absolute motion. What's the resolution here?
