Cosmic shear offers a remarkbly clean way to measure the equation of state of
the Universe and its evolution. Resolution over a wide field is paramount, and
Antarctica offers unique possibilities in this respect. There is an order of
magnitude gain in speed over temperate sites, or a factor three in surface
density. This means that PILOT outperforms much larger telescopes elsewhere,
and can compete with the proposed DUNE space mission.
