billslugg replied to the thread Argument by analogy.He is referring to all of the foreground radiation that must be subtracted from an image before they can see CMBR. It is not in the...

Like.
11°x3.5° field of view for SPHEREx. Make your math, please. ;) -
billslugg replied to the thread New NASA space telescope SPHEREx to launch in February — it can do what the JWST can't.Yes, I already knew all of that based on the first part of the article. The last part promised to give me specifics and it didn't. I...

Quite right! I must pay more attention! Re Background. The radiation of the CMB is of course everywhere. Assuming the universe is...

billslugg replied to the thread Argument by analogy.Actually, in radio terms, "static" is a noisy stuff we hear in between stations. It is perfect noise, that it, the energy is evenly...
-
The CMB is everywhere in the same way as people suggest the BB is everywhere. If that does not qualify for "stationary" I don't know...
-
I think a big misunderstanding here. No radiation is perceived as static. The CMB is assumed to be at rest. We measure whether or not...

Absolutely correct. Cat :)

billslugg replied to the thread Argument by analogy.CMBR is not static, it is composed of radio waves at several millimeters of wavelength coming at us from all directions at the speed of...

billslugg replied to the thread What are boson stars — and what do they have to do with dark matter?.Matter and energy are two different form of mass. Matter has mass and energy has mass. Matter and energy are interchangeable forms of mass.
