Researchers
have
developed
a
new
way
to
improve
our
knowledge
of
the
Big
Bang
by
measuring
radiation
from
its
afterglow,
called
the
cosmic
microwave
background
radiation.
The
new
results
predict
the
maximum
bandwidth
of
the
universe,
which
is
the
maximum
speed
at
which
any
change
can
occur
in
the
universe.
The
cosmic
microwave
background
(CMB)
is
a
reverberation
or
afterglow
left
from
when
the
universe
was
about
300,000
years
old.
It
was
first
discovered
in
1964
as
a
ubiquitous
faint
noise
in
radio
antennas.
In
the
past
two
decades,
satellite-based
telescopes
have
started
to
measure
it
with
great
accuracy,
revolutionizing
our
understanding
of
the
Big
Bang. Read
the
full
story.
