My favorite of these types of bizarro QM communities is that of the "holographic fractal" universe. Nassim Haramein[1] being one of the popular figures of this movement. If you're willing to sift through the mysticism, the r/holofractal subreddit has some interesting ideas to chew on during an otherwise dull lunch break.[2]
