Thanks for the feed back. The book is already written but I keep adding ideas to it. The original world was round like Earth but had a greater diameter. To get around the gravity problem I simply stated that there were great hollow spaces within the Earth. This became a convenient setup when I put, on the East and West pole, two massive geysers at each end. The planets inner core caused the water within the Earth to heat up and spew endlessly from both sides. This force is great enough to send the water out of our atmosphere and create a ring of liquid water around the Earth. The circling would only be temporary due to Earths gravitational pull so the water flows down near the East and West poles, only to again be thrust back up into space by the perpetual geysers. This endless cycle allowed for a thin atmosphere to follow around the ring therefore allowing ships to sail out into space and return on the other side of the world. This was my first idea and I really like the liquid ring idea but I’m experimenting with other ideas.

Thanks, I appreciate it.

I would also like to add, if I understand your original reply, If the ring is not spinning and there is sufficient gravity on the top flat side, and by moving to the outer rim one could fall off the world, this scenario would be the most desirable. Lots of possibilities in a fantasy world.

OK…let me try and get what you are saying. The ring will be spinning so lets say there are four sides to the ring (like the ring around Saturn: the inside side (facing the sun), the flat top of the ring, the outside side(dark side), and the flat lower side (facing down). How would gravity work on these four sides? Also…the idea that you could fall off the world is terribly fascinating. I would like to hear more about this possibility. If one falls off the world, where do they fall?

That's a good idea. I know some space stations operate like that. I know there will be a side of it that will never get any sun. I planed to get around the day and night thing with a cloud ring between the sun and the habited land. The cloud ring would be vertically thicker around half the circle allowing for night. As day turns into night the sun would appear to be shutting it’s eye. Of course the sun would always be in the same position.

Ya, I hear what you’re saying but I don’t want it to be obviously ridiculous. If it’s half possible then I will keep but, like I said, if it’s just scientifically irreconcilable then I have a problem.

First I would like to thank EvoN1020v, theCPE, and Klaynos for your responses. I’m afraid some of the answers went over my head. Let me start by explaining why I want to know. I’m writing a fantasy novel with a little science fiction thrown in. I’m toying with the idea of making a world that is like a great ring around a sun. I like this idea because one it’s different from the traditional round planet and two it would give me more than enough land to play with in my world. BUT, I need the gravity to be the same as on earth (or at least comparable). If this is completely implausible I might scratch the idea. If someone landing on this land(ring planet maybe) gets immediately sucked off it towards the center of the ring, which would be towards the sun, then of course that would not be good. My major question is: is it possible for me to finagle this scenario into the semi plausible area or would gravity either crush or fling all the inhabitants off the ring to an early death? Thanks again.

I know that gravity depends upon mass but what if the mass was spread out? For instance, Jupiter has a great amount of mass and therefore very powerful gravity but what if you flattened Jupiter into a great ring around the sun? Would any part of that ring retain the full gravitational force of the planet equal to when the planet was one round ball? Or would the spread out mass greatly affect the gravitational pull of the ring? I don’t know a lot about gravity so I have no idea. Need some help if you can. Thanks!!!
