Can we discern any movement by the microwave background perpendicular to its expansion?
You would probably need to break this down into a number of more tightly worded questions before it could, in principle, be amenable to testing.Originally posted by Loren Booda
Good enough. I. e., can cosmologically correlated redshifts (or anisotropies) in an expanding universe infer orbital motion as well?
MBR stands for Microwave Background Radiation, which is the leftover radiation from the Big Bang that fills the entire universe.
The MBR displays orbital motion relative to us because it is affected by the motion of our galaxy, the Milky Way. As our galaxy moves through space, it causes a slight Doppler shift in the MBR, which can be observed as a change in the frequency of the radiation.
Studying the MBR's orbital motion provides valuable information about the structure, composition, and evolution of our universe. It can also help us understand the dynamics of our galaxy and its place in the larger cosmic web.
The MBR's orbital motion is measured using specialized instruments, such as telescopes and satellites, that can detect and analyze the slight changes in the radiation's frequency. This data is then used to create maps and models of the MBR's motion relative to us.
The MBR's orbital motion provides evidence for the expanding universe theory and supports the idea that our galaxy is just one of many in a vast, ever-changing universe. It also helps us refine our understanding of the origins and evolution of the universe, as well as the fundamental laws of physics.
