Question	—	Why wouldn't my colonists go to see what's going on down there? I would like my human colonists to settle on the high plateaus (2500-3000m above sea level) of my planet thus never meeting the civilization living in the lowlands (in a huge forest so they aren't visible from above), until settlers find evidence of them and decide to see what's going on down there. ...

Question	—	Geostationary moon My planet is very Earth-like with a day length of 26.87h. The moon has a radius of about 1550km, a mass of $5.2\times10^{22}$ kg and orbit 45500 km from the center of planet. My scenario is that the formation of this moon is the same as our Moon (i.e. from a collision) but that the planet was spinni... (more)	—	over 5 years ago
Question	—	How tall could bamboo grow How tall could a bamboo-like (i.e hollow with nodes) tree be ? It should be at very least 1.5m of diameter and walls no more than 20cm thick. The internodes should be 2 to 5 meter long. I think it would need rhizomes etc and grow like bamboo does but you can change whatever you want. Something else I... (more)	—	over 5 years ago
Question	—	Anatomically correct radio communication Could animal produce less than 700MHz radio waves to communicate ? I don't want those waves interfere with mobile phones and other intercontinental radio communication my space colonists would use. Is it harmful, and could they produce an alternative current powerful enough to produce those waves? Is... (more)	—	over 5 years ago
Question	—	Flying Nightmare I found this thing source: http://aliens.wikia.com/wiki/FlyingNightmare In its dormancy it folds itself and it rooted to the ground. However when it detects prey, it hovers above and engulfs its victim, wrapping it in its embrace, paralyzing the prey as it consumes it. I would like to add somethi... (more)	—	over 5 years ago
Question	—	Oxygen producing metabolism What kind of realistic oxygen producing reaction used by life could exist in a carbon dioxide / ammonia atmosphere? There are also many volcanoes, either immersed or not, water oceans and you can even use silicon oxides or whatever from the crust of my Earth-like planet. The further it is from our ac...

Question	—	How big does a moon have to be to have the earth locked to it? I would like a earth-moon system like Pluto-Charon (but with earth instead of Pluto) where both will be tidally locked to each other within something like 3 billion years (before complex life appears). As the moon would probably lock to earth before the opposite it depends only on the mass of the moo... (more)	—	over 5 years ago
Question	—	Oceanic crust formation I'm working on a earth-like planet with a much lower sea level (like 3000m so the mid-ocean ridge would form many islands) but is that even possible? Will the emerged ridge make some weird stuff and won't it prevent normal plate tectonics? (more)	—	over 5 years ago
