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?
Maybe not an alternative site, but an alternative perspective. Instead of looking at all items on lemmy, try finding and subscribing to communities that pique your interest, then viewing by subscribed communities.
I know it’s not what you were specifically asking for, and it’s a little more work than just sliding into another site, but it will give you the opportunity to weed out information you are not interested in.
Some communities on here are pretty close
The mander.xyz communities for example
