- Frame of Reference
- … frame before the CMB was known — the rest frame of the substratum, whose fundamental observers see the universe as isotropic — and the CMB later made that frame observable: its dipole anisotropy, first detected in 1977, is read as the Earth's motion relative to the radiation (then measured at 390 ± 60 km/s).
This sourceDetects a dipole anisotropy in the cosmic microwave background with a U-2-borne 33 GHz radiometer and interprets it as the Earth's motion relative to the radiation (about 390 km/s), making the CMB rest frame an observable reference.

Verification¶
Does it exist? Not checked yet. This work's DOI is recorded above but has not been resolved against an external catalogue, so nothing here confirms the work exists.
Does it back the claim? Not recorded. The single citation of this work carries no recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
