Question	—	How hard would it be for humans to colonize an exoplanet with a size significantly different than that of earth (but otherwise suitable for life)? If you look at this list of potentially habitable exoplanets, very few of them actually come close to having the same size as Earth, this means most of them would have surfaces gravities significantly different from those on Earth, and mostly likely significantly different atmospheric pressures as we...

Question	—	Where would space habitats get their oxygen from? Suppose you want to build a large scale habitable structure in space or on a planet or moon without an atmosphere or any organics, and this would be a long term or permanent settlement, not a temporary location. Where would you get the oxygen for its inhabitants to breathe from? And, if you got it fr... (more)	—	about 6 years ago
Question	—	Would total reliance on Solar and Wind energy sources lead to climate change? If Humanity were to suddenly come to its senses and stop relying all together on fossil fuels and start relying on wind powered and solar energy sources, wouldn't this lead to some sort of climate change? The reason why I am wondering if this would happen is the following: Large scale reliance o... (more)	—	over 7 years ago
Question	—	If true interplanetary and interstellar travel were achieved, would the decreasing mass of the earth become a problem? Assuming that in the not too distant future space travel developed enough, that large numbers of ships and people were leaving the earth's surface on a regular basis. Would this ever reach a point were the amount of mass leaving the earth became dangerous? Would the resulting decrease in mass lead ... (more)	—	almost 8 years ago
