About
This channel focuses on exploring concepts in science with an emphasis on futurism and space exploration, along with a healthy dose of science fiction. While we explore many concepts and technologies that are far beyond us now, we try to keep everything inside the bounds of known science or major theories. Isaac Arthur is the creator and producer of SFIA, and the President of the National Space Society.
