This is the jist of the astral planet concept. What do you guys think? Interstellar (the movie) inspired me to share the idea/story with fellow meditators.
Interstellar is an exceptional film and the main consultant, the theoretical physicist, Nobel prize Kip Thorne, has made it likely from the scientific point of view. Kip Thorne has a few videos explaining black holes and I think he gave the best explanations for it, keeping things simple and clear.
However, I'm missing the link between that film and the astral plane. What I'd like to do is to buy Kip Thorne's book on "The physics of interstellar", it should be read while viewing the film. This is a goal for when I'll have more time.
