Polarised
light of the
cosmic
microwave
background,
the remnant
light of the
Big Bang, is
sensitive to
parity-violating
physics. In
this
presentation
we report on
new
measurements
of parity
violation,
called “cosmic
birefringence”, from polarisation data of the European Space Agency
(ESA)’s Planck
satellite. The
statistical
significance
of the
measured
signal is
about 3 sigma.
If confirmed
with higher
statistical
significance
in future, it
would have
profound
implications
for the
elusive nature
of dark matter
and dark
energy.
