Henrietta Swan Leavitt,
discoverer of Leavitt's Law


A hundred years ago cosmologists were struggling to understand the nature and structure of the universe, and at the heart of this struggle was the island universe hypothesis.
Today we find ourselves confronted with a similar question posed at a far greater scale. As we confront these great questions of cosmology, whether a hundred years ago or today, we find ourselves faced with as many philosophical questions as scientific questions when we challenge the boundaries of our understanding. In Part I we focus on the original problems of constructing the cosmological distance ladder.

Population was 2,248,374 in 2010, and the population dispersal is the following: 68 % live in cities and towns and 32 % – in rural areas. https://www.baltic-legal.com/latvia-facts-eng.htm
