Cosmos 03 - DVD pošeta

Carl Sagan supported the SETI program, which seeks to search for extraterrestrial civilizations. Thanks to Sagan's reputation, the world's largest astronomical facility, a giant radio telescope with a 300-meter diameter dish in Arecibo, Puerto Rico, became involved in this program. Scientists here tried to capture the 'voices of aliens' and discover apparent signs of extraterrestrial intelligence. So far, without success... The Bushmen of the Kung tribe refer to our Galaxy, which shines above us as the Milky Way, as the Backbone of the Night and believe that if it weren't for it, pieces of the sky would fall at our feet. However, modern humans often live amidst myths and misconceptions. Do you know, for example, what stars are and how long they shine? Why is our Earth round? Is it possible to exceed the speed of light and thus travel in time according to Einstein's theory of relativity? Thanks to Carl Sagan's imagination, yes, and we can easily return to the moment of the Big Bang and witness the fascinating spectacle: the birth of our Solar System and indeed the entire universe. So let us embark once again with astronomer Carl Sagan on a voyage across the ocean of eternity.
