I want to watch Cosmos again but I worry about its age -- what should I keep in mind when watching?
Since the original airing of Cosmos in 1980, there have been numerous scientific discoveries in various fields such as astronomy, physics, and biology. For example, the discovery of exoplanets, the confirmation of the Higgs boson, and the mapping of the human genome were not known or understood during Sagan's time. These discoveries may expand upon or contradict some of Sagan's theories, but they do not render his ideas completely outdated.
Our understanding of the universe and its origins has significantly evolved since the filming of Cosmos. For instance, the theory of cosmic inflation, which explains the rapid expansion of the universe after the Big Bang, was not known at the time. Additionally, advancements in technology have allowed us to gather more accurate and detailed data about the universe, leading to new insights and theories about its origins.
While some of the terminology used in Cosmos may be outdated, such as referring to other galaxies as "island universes," the overall scientific concepts and principles discussed in the series are still relevant and accurate. Sagan's explanations of topics such as evolution, the scientific method, and the nature of the cosmos are still widely accepted by the scientific community.
Since Cosmos, there have been many advancements in the search for extraterrestrial life, such as the discovery of microbial life on other planets and the identification of potentially habitable exoplanets. However, our understanding of the potential for intelligent life beyond Earth has not significantly changed since Sagan's time. The search for extraterrestrial intelligence continues to be a topic of scientific research and speculation.
Yes, Cosmos is still relevant in today's world as it presents fundamental scientific concepts and principles that are timeless. While some of the specific examples or terminology may be outdated, the overarching themes of curiosity, exploration, and the wonder of the universe are still relevant and important for society to understand and appreciate. Additionally, the series continues to inspire future generations of scientists and thinkers to explore the mysteries of the cosmos.
