Epic constructions beyond fathoming. Either that or desolate metal plains leading off into the vacuum of space. Take your pick. -=Moxus=-
You get to the end and when you fall off, you appear on the other side. Same thing as when you reach the end of the Earth. Either that or you fall down into hell.
Nobody knows, and nobody ever will. There is an army or 10000 ninjas guarding it so that nobody can ever get close enough to see. Sorry to be such a killjoy.
Is gravity on the Halo rings maintained by some kind of artificial generator or by centrifugal force? If the former, you walk around the edge and stand on the outside. If the latter, you go spinning off into space.
Neither. Its centripetal acceleration. I wrote an essay on it for my Physics A Level. I calculated a the smallest space station you could make, which would provide you with an acceleration of 9.81 m/s^2 and not rotating too fast to make the people on board dizzy, would be just over 55 metres rotating at about 4 rpm. The Halo Rings have a much larger radius so don't have to rotate as fast to produce the same 9.81 m/s^2 and the Coriolis effect is less apparent. In theory, if your station/Halo had an radius of infinity then it wouldn't have to move. Thats why I don't like the Ark's design, or the Dyson Sphere's actually. They don't make sense like the Halo rings. When inside a Dyson Sphere, the only place you could reproduce the effects of gravity would be along the equator. The density of the ground below can't be responsible for the gravity because the force of the ground above (of which there is more) would pull you up. Everything would fall to the centre. So the only thing that makes sense in space in Halo are the Halo rings. All the ships, the Ark, Dyson spheres all must rely of the convenient gravity machines... which I hate. ...that doesn't really answer your question. The Flat Earth Society (the stupid people who refuse to believe the Earth is round) think that there are enormous mountains of ice surrounding our disc-like planet. Of course this makes sense, space is so cold water freezes, the edges of the Earth are in contact with space, therefore the edges of the Earth are frozen walls of ice. This is why the water just doesn't drain away over a big waterfall. But I think there probably is a big concrete wall to stop people walking too far. Its not like you could just walk on to the other side. That 1G holding you in the ring before is now 1G throwing you away from the ring.
Well, in the Halo universe, the Forerunner had artificial gravity, which the Covenant copied from them which the humans eventually copied from them. I just don't know if the Halo rings have it or not. source
I like how the Halo rings work. But technically, on a Halo ring, or any ship with similar artificial gravity, you will forever be walking uphill if you follow it around. On the plus side, on a small version of a Halo rign, you could possibly see someone standing above you. What would happen if you were on a small one and you had a jetpack and went to the centre?
Cookies But the only problem is that the cookie monter is guarding them... and we know how serious he is about cookies
Realistically: Since halo's gravity comes from the force of the ring spinning, as you nearer the edge, the gravity will get more and more immense, pulling you back. If you made it past this gravity, then you will be flung out into space and since the gravity holds the atmosphere, there will be none and you will explode. Cool way: After years of walking to the edge of halo (probably should have driven), you find the magical edge which has magical properties and you turn into a flying gingerninja with super ninja powers.
It's all about the inverse-square law. Gravity can exist pretty fine on both structures providing there is enough mass directly below you at all times. The stuff far away doesn't distort it because of the inverse-law.
I read a book called RingWorld by Larry Niven and it showed how something like a Halo could work (only that version was around a sun and had microscopic-unbreakable cables connecting it to the sun so the whole star system could be moved) On the edge there were walls 2 miles high to keep the air in. Nothing really spectacular (exept for the miles and miles of special plants that reflected sunlight en mass and burned everything to a crisp)
a huge wall of metal. behind that, huge superstructures of maintenance equipment so complex they can only be maintained by machines designed for the job
