The Universe is
expanding gradually now.
But its initial expansion was almost impossibly rapid as
it likely grew from quantum scale fluctuations in a
trillionth of a second.
In fact, this
cosmological scenario, known as
is now reported to be further quantified by an
analysis of three years of
data from the WMAP
WMAP's instruments detect the
radiation - the afterglow light
from the early Universe.
WMAP's amazing success in exploring the first trillionth
of a second and favoring specific inflationary scenarios
lies in its ability to make unprecedented,
measurements of the properties of
the microwave background.
The subtle properties are distilled from conditions
in the early Universe and related to its first moments of
