pattern in the
polarization of the cosmic microwave background, known as a «curl» or B - mode
pattern.

On Monday, March 17, 2014, BICEP - Keck collaboration, which operates an array
of microwave telescopes located at the geographical South Pole, announced the discovery
of patterns in the
polarization of the cosmic microwave background that could have been generated in the early universe.
The theory is that these photons produced a curling
pattern of polarization, called a B - mode, that is causally connected to what happens when an electron interacts with a gravitational wave.
Dust grains in the Galaxy could imprint a similar
polarization pattern in the CMB as gravitational waves can, but based on several different predictions
of the galactic contribution the researchers concluded that their data was more likely to originate from primordial gravitational waves.
This
pattern, basically a curling in the
polarization, or orientation,
of the light, can be created only by gravitational waves produced by inflation.
The
polarization pattern that BICEP2 detected in the CMB could effectively be a snapshot
of primordial gravitational waves.

polarization of the ferroelectric material up and down, creating a geometric
pattern of concentric squares.
Not only did the group succeed in visualizing the real time events
of zygote
polarization and asymmetric cell division, they were able to quantify the dynamic
patterns of the cytoskeleton (i.e. formation
of the ring structure and longitudinal array
of MTs and F - actin, respectively).
That could be detected by looking for a particular
pattern of polarized light in the cosmic microwave background, known as B - mode
polarization.
