I have several questions regarding this topic.
First, could a water world be stable for thousands of years with most of its surface remaining covered in water. What would it take for this to be possible?
Second, in the said world, would it be possible to have an atmosphere stable for human life? By stable, I mean oxygen levels near 20 percent without any harmful toxins. What would this require to be maintained?
Would it be possible for this world to exist with no moon, no tidal forces, and to be locked from rotation? Would there be any sort of tide or waves associated with the water in this condition?
How far from the Sun would it have to be located to be safe for human life, and what might the Sun look like in the sky? Would the Sun's position in the sky remain constant?
I'm sorry for the abundance of questions. I don't know where else to find the answers, though I've read several books on the topic. I've heard of Excel spreadsheets that will help you answer these sort of questions, but I don't know where to find them or how to use them. Any help would be most appreciated!
One final thing: When I say water world, I mean water as we know it (H2O) and not some sort of sulfur ocean or any other such thing.
Have I failed to ask about other in-depth information on this type of planet?
