Abstract

In introduction, the first attempts in understanding natural
phenomena and searching answers on cosmological questions,
from pre-socratic philosophers to Aristotle then to Newton, are
considered. Scientific cosmology of the 20th century is founded on
Einstein’s General theory of relativity and the equation of field gravity,
which was later derived by different approaches of Friedman and
Lemaître; the equation solutions show an expanding universe from
a singularity, and the beginning of universe and Big Bang, that one
takes as a standard cosmologic model today. Also another alternative
model with a theory of the steady state universe is considered, which
is meanwhile abandoned after new cosmologic discoveries and
empiric arguments in the second half of twentieth century. Apart
from open questions of modern cosmology, convictions and world
views of some scientists are also given.
