The question is about what changes would have to be made to an Earth-like planet, in order to increase the density of air and hence make lifting gases more effective. If that is scientifically poss...
Suppose one fine day a mischievous god decided to eradicate all air molecules on Earth in an instant, my question is what will hapen to the ocean? Please kindly disregard (omit) your concern for li...
Let's say on an alien planet called Thindor, the surface gravity is 3.27 m/s2 (which is 1/3rd of Earth's). But the atmospheric pressure is only 50 kPa (which is 1/2 of Earth's). Assume the same 20/...
I'm starting a whole new planet for a story and would like it to have an orange sky during the day. At a basic level (I am not a smart man) what chemical composition would be most conducive to Ora...
The Scenario: The Sun is eternal. We are producing much more oxygen than we need. First off, would the atmosphere grow, or would it just become much more dense? Given the circumstances, if th...
I'm wondering what adverse effects might be felt by someone from a planet with, say, 80% of Earth's gravity and a denser, but breathable, atmosphere with a higher concentration of oxygen visiting a...
Ignoring the fact that we need water in order to survive, what would happen if all of the "oceans" on Earth were filled with a dense non-reactive gas (e.g. xenon or sulfur hexafluoride) instead of ...
Ok, so I have this planet that I am still building. It is a desert planet, its surfice is almost completely arid with a few exceptions such as snow deserts in the poles. There is sentient life in ...
This is about a fictional planet that has a solid land surface but on which the atmosphere is composed of some liquid containing hemoglobin, or some artificial blood substitute. I am not sure yet ...
What physical attributes of atmosphere and flora could cause clouds to form on a regular basis below the canopy of a forest between one-fourth and one-half the height of the forest, without impacti...
Apologies; it just didn't seem like an appropriate question for Earth Science or Biology. Let me know if I'm incorrect. Maybe Physics? If all the ice, permafrost, ice caps, etc. melted due to glo...
I want to have an upper atmosphere composed of a gas which is lighter than "air" so that my human occupants of a planet can harvest it and use it to fill blimps and hot air balloons. I'm planning ...
