Our world is a speck in the universe filled with trillions of stars and planets. The starry night sky is beautiful, but a few may wonder, “Where are they?” That is the biggest unanswered question coined the Fermi paradox named after the physicist, Enrico Fermi.
In a recent episode by Kurzgesagt – In a Nutshell (previously), they examine the Fermi paradox and possible reasons why there aren’t other civilizations. Discovering other forms of life requires some technological advancements, and they explain the Kardashev scale, which categorizes civilizations into three types. They also cover the Dyson sphere, colonization in the galaxy, and theories of the filters civilizations need to overcome.
One final thought, maybe we’re alone. Right now, we have no evidence that there’s any life besides us. Nothing. The universe appears to be empty and dead. No one is sending us a message. No one is answering our calls. We may be completely alone trapped on a tiny, moist mud ball in an eternal universal.
