- TL;DR Summary
- Does FLWR metric coordinate and CBR homogeneous coordinate where the Earth has proper speed of 0.0013 c coincide ? If so why ?
The Earth is moving with respect to the CBR at a speed of 390 kilometers per second, I read in the article https://www.scientificamerican.com/article/how-fast-is-the-earth-mov/. Does FLWR metric coordinate space coincides with integrated local FRs where CBR is homogeneous, and the Earth is moving with 390 km/sec = 0.0013 c on it ? If so does the coincidence of CBR homogeneity and FLWR metric space have any reason or just by chance ?
