Cool Worlds | Artificial Gravity @CoolWorldsLab | Uploaded 5 years ago | Updated 10 hours ago
Artificial gravity is a concept that is ubiquitous in our science fiction yet elusive in our space program. Why is this? And how could we develop artificial gravity soon? In a Cool Worlds special, this video essay goes in depth on the topic discussing why centrifuges are the most plausible solution and early ideas on the topic. Join us a journey from Einstein's equivalence principle, to O'Neill Cylinders and Stanford Tori; from Coriolis forces to near-term experiments. Grab a cup of a tea and enjoy.
