Recently, looking for information for worldbuilding purposes of my story, I found a post about how in a more oxygen rich atmosphere, the oxidation processes would take place more quickly. ...

I am looking for information on how the trees and the flora would be in a world with a denser atmosphere and stronger winds. I have read that due to the greater kinetic movement of the wind, that in ...

First of all, I am aware that its impossible for a planet with less gravity than the Earth, to naturally maintain an atmosphere with the same terrestrial gases, in an equal or greater proportion. ...

I'm writing a sci-fi/fantasy story that partially takes place in a supercity (Pop 15 Bil) made of skyscrapers. The inhabitants thereof are immortal, and so don't have to be concerned about atmospheric ...

Basically: I want a highly viscous atmosphere but I want people to be able to walk around. I was thinking earth's gravity * 0.6 or similar. I was thinking that an atmosphere of Sulfur Hexafluoride ...

You've got to love the rainbow, it's an awesome sight. But I don't want humans to have the pleasure of seeing the rainbow. What change to the earth, atmosphere and so on, is needed so that humans ...

Say there would be plants that release a lot of N2O (nitrous oxide or laughing gas). On Earth, N2O is a trace-gas and it is pretty stable. In our atmosphere it has a half-life of > 100 years, and as I ...

Or would the heat dissipate back into space? For my world building purposes, I need it to cause global warming, I just don't really know if it would work. Maybe the cities would need to be bigger then ...
