16. The cosmic microwave background radiation (CMB) is radiation
that bathes the Universe from every direction, and appears to be
emitted by a blackbody at a temperature of 2.7 Kelvins. This
radiation
a. comes from stars.
b. comes from supernovae.
c. is the redshifted glow of the hot young universe, appearing
much cooler today.
d. consists of cosmic rays emitted by dying stars.

The cosmic microwave background CMB is a primordial glow of
electromagnetic radiation which comes to us with almost equal
intensity from every direction in the sky. The CMD shows a
characteristic pattern of very finite bright and dim patches with a
typical patch separation of 1° we would like to patch a telescope
that can resolve these bright and dim patches distinguish two
sources in the sky separated by 1°
suppose that we build our telescope to measure the CMB...

We often say that the cosmic microwave background radiation
(CMB, or CBR) is a direct viewing of the Big Bang. But actually,
the temperature of this black-body radiation (3 degrees K) is
insanely low for the Big Bang. Why is it so low, when the Universe
started out so hot? And why do we say now that the CMB represents
light from about 400,000 years after the Big Bang, rather than the
Big Bang itself?

1. The Cosmic Microwave Background and Prizewinning
Cosmology
(a) How can we see the CMB if the photons were released 14
billion years ago? Shouldn't those photons be billions of light
years away by now?
(b) Who was awarded the 2006 Nobel Prize for Physics? What was
the prize for-- what were the results, and how were they
obtained?
(c) Why are these results from part (b) important?
