Question	—	How far above the galactic plane could an Earth-like planet develop? I was zooming around on Space Engine and came across the moon of a gas giant that was hovering well above the galactic plane. I'm admittedly not well-versed in under what conditions an Earth-like planets can form, but it got me wondering... is it possible for a terrestrial planet capable of life to f...

Question	—	Are 'tree waterfalls' possible? Something like the above (Natural Springs by Ellie Cooper) - either where the water originates from atop the tree through regular rainfall, or is directed up and into the tree via the spring (or some other source) below - somehow. I'd ideally like these to be created naturally, but man-made alterat... (more)	—	over 4 years ago
Question	—	What are planetary side effects of having a thicker atmosphere? I've been told that having a thicker atmosphere would make it easier to fly, particularly of heavier-than-air designs, so I'm interested in giving my planet such conditions. I'm mainly interested things like temperature, weather, seasons, the distribution of land versus water - basically, how the pla... (more)	—	almost 5 years ago
Question	—	Is it possible to introduce life to a planet via preserved organism? The dominant religion on my world (created by a race of dragon-like humanoids) believes that their species originates from an ancient being that sacrificed itself to defeat a great evil at the center of the cosmos. Its body remained adrift in space until it was eventually captured by the gravity of ... (more)	—	almost 5 years ago
Question	—	How could an Earth-like planet support all-metal airships? When I say all-metal airships, I'm referring to something like the above from Jakub Rozalski's artwork - the design is more akin to a naval destroyer or battleship and less like a zeppelin. We've seen metal-clad airships before but they didn't seem to work out too well. The level of technology i... (more)	—	almost 5 years ago
Question	—	What impact would a dragon the size of Asia have on the environment? Without going into unnecessary detail, one of the races of my world believe that the land itself is a dead god, and that by resurrecting it, it will ascend to the cosmos and carry the faithful upon its back. The form they choose to represent this great god is born out of their own image, and represen... (more)	—	over 5 years ago
Question	—	Is it possible for thermophilic viruses to infect humans? I'm writing a short story that focuses on an area with high thermophile activity, like a hot spring. There are known thermophile viruses, but thermophiles aren't able to transmit these to humans because our bodies are too cold. So we don't know what exactly these viruses could do to a human host if c... (more)	—	over 5 years ago
Question	—	Developing a scientifically accurate species of dragon-like humanoids I'm trying to figure out a way to make this species as I envision it while still maintaining scientific realism. I want to get it as close to "yes, this could exist in the real universe" as possible. If you want a quick visual primer: something like this or this - but with wings capable of flight and...
