So, lately, I've been studying things like the Fermi paradox, and the probability of parallel universes and worlds, and quantum physics and biology....and I have so much to discuss with people, but no one to talk to about it (apart from my boyfriend).

Does anyone know of any communities online where I can discuss with people the universe? I really want to further my knowledge on these topics, and discuss theories. Or should I start my own? But who would join?
