I mean, I GN an adult Dungeons and Dragons centered on multiple worlds and I love considering different worlds and how they might work. But the people who extrapolate the unexplained to a claim that there's some fantastical things that science is suppressing seem so starved for "the fantastical" that they're distorting the entire situation. Science isn't there to squash your fun. Science doesn't deny that uncertainty is a constant part of ordinary human experience - scientifically established positions are merely a reliable tip of an iceberg of uncertainty.
