Isaac Arthur YouTube Channel
Are you a fan of Science Fiction? Like writing about future worlds, advanced technology, and the possibility of alien life? Spend some time with Isaac Arthur, host of a very prolific series of videos on YouTube, where he discusses all aspects of space and future science. His videos are quite in-depth (each video runs around 35-45 minutes), and he spends a lot of time pulling the subject apart and building it up from the basics. These videos are great for the layperson and the scientist alike.
I’m a big fan of world-building, and these videos are a great source of inspiration for me.
In the following video, discusses the concept of Ecumenopolises, cities which span entire planets.
