Observations of the cosmic background radiation
show that the universe had a predominantly uniform consistency after inflation, except for a light sprinkling of some regions that were more dense and others that were less dense.
Next to alternatives for the theory of relativity and the stretching of light, scientists have found alternatives for the third pillar of current conventional cosmology, the cosmic background radiation
discovered in 1965.
Two upcoming satellite studies of the cosmic background radiation
could yield evidence for or against a fourth neutrino's existence.
The Cosmic Background Radiation
Explorer (COBE) launched in 1989, confirmed the prediction made by the Big Bang theory.
His description of the work that went on behind mapping the cosmic background radiation
with the Boomerang telescope is, for someone who's read about this too many times, fresh and even inspired.
The pattern of temperature fluctuations in the cosmic background radiation
offers a critical test of the global topology of the cosmos, Levin says.
However, less energetic electrons can still produce X-rays by interacting with the pervasive sea of photons remaining from the Big Bang - the cosmic background radiation
The cosmic background radiation
is far weaker in every other waveband.
These show their presence as minute temperature variations in the cosmic background radiation
from the Big Bang, as observed by experiments such as WMAP.
If, at the end of that process, you get the same underlying pattern for fluctuations in the cosmic background radiation
, then that would be a convincing result.
7[degrees] Kelvin cosmic background radiation
confirmed that the whole cosmos is toasting in a microwave oven.
Loeb notes that the cosmic background radiation
- photons left over from the universe's explosive birth -- had a high density in the young universe.
If patterns of some kind were imprinted upon the infant universe by still-mysterious processes and have been amplified by gravity, as contemporary cosmology maintains, there ought to be a statistical similarity between today's galaxy distribution and the ripples in the cosmic background radiation
