A cosmic surveyor: measuring distances in the Universe

Abstract:
Following a cosmic surveyor who tries to measure the distances to cosmic
objects, we encounter a fundamental question: what is the geometry of
space and time? Attempts to answer this question led to beautiful ideas
of General Relativity and recent breakthrough discoveries in cosmology.
