Urknall bis heute: Die Geschichte des Universums in Farben | Sternstunde Philosophie | SRF Kultur

The universe is far more than a black night sky. Astronomer and science communicator Florian Freistetter shows how the colors of the universe tell its story – from violet planets to the light that makes the Big Bang understandable. Topics in this episode: 00:00 What can we see with the naked eye and what can't we? 20:10 Why do you communicate science with cabaret? 27:56 How should we imagine the expansion of the universe? 46:06 Will we one day encounter extraterrestrial life? What color is the universe? No one who has ever looked at the night sky would ask that. The answer seems clear: black. But astronomy knows better: The cosmos is much more colorful than our eyes can perceive. And it is only thanks to this diversity that we can learn anything about the universe at all. For example, what the expansion of the universe and the related theory of the Big Bang are all about. In his latest book, Florian Freistetter traces the history of the universe through its colors. He explores the entire rainbow. What do violet planets reveal about the origin of life? Why is the sun actually green? What existed before the Big Bang? And why was there truly light at the beginning? Olivia Röllin discusses these questions with him in this episode of "Sternstunde" (Philosophy Hour). A philosophical and scientific expedition through 13.8 billion years of cosmic colors – and a look at how much our understanding of the universe is shaped by the limitations of human perception.
