Ringworld Flyby

This simulated flyby of a ringworld shows the essential elements: the ring with sidewalls to retain atmosphere and the shadow panels to create "night and day"




Please note that this is not an attempt to accurately depict a ringworld as described by Larry Niven, but rather depicts the basic mechanisms by which some features of a planet are mimicked in this type of artificial world.

This isn't close to accurate.  The ring is entirely the wrong dimensions in relation to the sun, the walls are much to high / visible, as they are only 1/10th of 1% of the width of the ring. The shadow squares are much too close to the ring. The ring is too thick. You didn't even read the book, did you?

Please read the description of the video and the channel. The purpose of this animation was to convey to students the possibilities presented by "an arbitrarily advanced civilization", and the mechanisms by which an artificial world could mimic the features of a natural world. It is NOT an attempt to depict a particular manifestation of a ring world, say that of Larry Niven or from the game Halo, although most of my qualitative features do come from Niven's Ringworld series.

Consider that the Ringworld is 997,000 miles wide (=1.604*10^9 metres) and that our sun is 1.392*10^9 metres in diameter, the Ringworld should be about as wide as the star is tall.

Thus it would be cheaper to have the shadow squares closer to the sun (I believe).

[mrg3]

I'm not sure why the ring would need to be as wide as the star, could you elaborate?

I've just assumed that the ring and squares would be thinner than the star. In that case complete shading is accomplished with less square when it is close to the ring. If the square, ring and star are of the same size, than and square distance would work. If the ring is bigger than the star, than the cheaper shadow square would be closer to the star.

your shadow squares are to far from the sun, and should be orbiting retrograde.

@HaloReplicas why, what did i say? because you're right.

[1993DJC]

@HaloReplicas Actually I beg to differ. Halo didn't come from Ringworld. Both Ringworld and Halo came from the idea of the Dyson Sphere. It was a concept that they both took. Bungie thought it would be a good idea for the Forerunners in the Halo series. It is about as original as having a dragon or a time-machine in a story.

[HaloReplicas]

@brandeezy108 you mean, halo is a really small version of ringworld

[HaloReplicas]

@1993DJC yes, THIS is what the idea of halo came from

@marocon60: If we want to recreate a proper haven for life, then we do need night and day, as they have significant impact on the ecosystem. Further, it would help if they were about the same period of time as the planet from which the ecosystem came.

[marocon60]

And is the whole night and day thing a necessary element?

[marocon60]

Why put the shadow squares right next to the ring? Wouldn't that just increase the surface area required for the squares and present the danger of the squares falling on the ringworld?

And must the walls be so wide? Considering the height of your ringworld, it just seems wasteful.

Also, it seems that the Ringworld exists at alot less than 1AU. What do you do to remedy this? Same question with meteor defense and the lack of attitude jets.

@kyrcant this is a friggin youtube video, how else do you expect anything to be visible? its like other space related videos, you must exaggerate the scale for anything to even be visible, otherwise all you'd ever see would be faint dots in the distance.

Halo!
