It is fun to think about the Simulation Theory but most discussions revolve around it being likely that we are in one.

What are some concrete reasons why it's all science fiction and not reality?

Looking for something like Hacker News but not about tech or programming.

Looking for something where people post or comment about Science, Physics, philosophical things, Simulation Theory, the Multiverse, or crazy "what if" hypotheticals.

Looking for the format of Reddit or Lemmy but with out all the negative comments and downvoting.

Are there any sites like that?
