Winged humanoids are popular in scifi, but due to the square cube principle (weight increases faster than strength), it's a nonstarter.
I have seen people say... but what if their world is lower gravity with a thick atmosphere?
A few challenges there that I am not sure can be overcome.
1. The moon Titan is such a place, yet I have read that the reason it's dense gases do not boil off and evaporate into space is because it is so far away from the sun. So sure, people could fly there... and get frost bite in minutes or less... even if air was breathable there.
2. Moving a Titan-like world closer to the sun to improve the frigid temperatures I have read would make the gases evaporate away into vacuum, since the gravity of Titan is rather low anyway. I do not know if this is true, but I suspect it is, since our moon is larger than Titan and is not holding an atmosphere, likely because it could'nt, unless the gases in question were the heaviest you could find so they would hold more readily to the surfaceThat's one planet type that likely could not host Earth life and exist. Anymore you got? Or want to discuss?
