Ich schreibe ein Belletristikbuch, das auf einer Ringwelt spielt
(Ein riesiges künstliches Konstrukt mit einem Volumen von Millionen von Erden,
z.B. Larry Niven)
Ich versuche herauszufinden, ob Sie die Krümmung des Rings erkennen können
Bodenniveau?
Ich habe versucht, es nachzuschlagen, kein Erfolg.
Vielen Dank für alle Informationen, die Sie uns geben können!
Edit: Vielen Dank an alle für die hilfreichen und anregenden Antworten!

Yes. For the most part it would look like a glowing line across the sky, except where it was in Shadow
I recall in the Niven books the inhabitants calling the sky „The Arch“, which is what it should look like
Probably. The thinner the atmosphere, the easier it would be. The Niven ring world was so flat that atmospheric haze blocks the view of the horizon. So you see the ring in the sky, but you don’t see th curvature rise off of the ground.
Play Halo 1, see ring, admire ring
I believe in the original book, there is a character towards the end who’s trying to walk to the „arch“ which is the ring seen far up in the sky.
I think he was a native of Ringworld.
It’s been years since I read the book so it might be in the sequel instead.
You wouldn’t be able to tell that your immediate surroundings curved, but you would see the ring curving in the sky.

here this could help you.
Niven’s Ringworld is insanely huge, it’s diameter is equivalent of the orbit of Mercury, IIRC.
I don’t believe you would see the curvature from ground level, the curve would be beyond the limits of human vision in atmosphere, it would probably have a weird effect of „thining“, before disappearing into the haze of distance.
In the books they can see „the arch“, i.e. the ring curving around the star, during the shadow-panel night, but I suspect it’s so big you wouldn’t see much more than a thin line, if that.
I could be wrong though, would be interesting if someone has done the proper math.
On smaller ringworlds, such as Halo, you might be able to see the curve, but not certain.
You’d get a lot of atmosphere between you and the ring’s nearest neighbors, so it probably wouldn’t be visible in the horizon. But above that it would fade in.
Just a guess tho.

I made a Fragment Swarm setting where there’s a conspicuous absence of a halo/ring (the gap is to vent excess heat off of the star, allegedly.)
You can see my rendering here.
I’ve often wondered this. If I remember correctly, Ringworld is a million miles wide. So if you’re looking toward the horizon, would it look like a very tall triangle, or just a thin vertical line in the distance?
Given a stupid thought experiment on my part: I can see the curvature of the earth – it’s the horizon.
I think of an inverse horizon that bends upwards… you’d see it in a vacuum. The question becomes light and atmospheric conditions.
As a question of geometry and scale, yes – you would see it.
that image makes no sense. It’s a flat landscape that suddenly turns up at the very end.
The options for that to be geometrically correct would require a VERY distended lake and city in the background, for example.
When you first saw the ringworld were you blinded by its majesty?
Yes, unless it was just insanely large in diameter with a super dense, opaque atmosphere. Atleast that sounds right to me, i guess well see after someone builds the first ring world! Lol
With almost 8,000 hours into Rimworld I can tell you this: nobody lives long enough to care.
Hey OP – not a scientific answer, more a literary guide. Use your imagination and describe it as you want it to exist. Then, work backwards from that and try to figure out the physics, scale and conditions that satisfy your vision.
And if you’ve conceived something truly absurd and impossible… you can try to deconstruct that with thoughtful (and fictional) explanation.
Of course not because it is flat 🤣
>millions of Earths in volume
The sun is about 1.3 million Earths in volume. So you’re really talking about something the size of several of our suns.
And you can see the sun from here despite it being a distance of over 100 suns‘ diameters away from us.
So something that is multiples the size of our sun could be seen from at least 100 light years away, assuming it was emitting enough energy (light, radiation, etc.) to be detected.
In sum: yes, you could see it, easily, although depending on the width of the ring it could appear a faint line in the sky or it could be chonky if the width is significant.
As for the curve itself….. you probably couldn’t see the curve. It would just taper off and appear as a straight line. The curve might really only appear on the parts closer to you and if you were on the edges of the ring. Once it hits a certain distance it’s just a line. It does depend on how wide the ring is.
I don’t know anything about your story, but you might want to revisit the sizing elements to be more in line with what you’re really trying to communicate. Unless you did in fact mean something significantly larger than our sun.
Yes you would, *extremely* clearly. The ring is in full sunlight at all points and has a very high albedo. You can see Jupiter, much further away, and with a lower albedo.
Niven describes what it looks like.
My recommendation: grab a copy of Bryce or Vue and actually build it to scale, set up your camera at the protagonists’s height sitting and standing, and then render from looking forward, backward, and up. That will give you a really good idea.
Definetly look into the game Halo… it makes this feel very real.. also… multiple ring worlds…
IIRC, the Ring is the width of Eaths diameter.
Circumference same as Earth’s orbit .
Rims high enough to hold atmosphere equal to earth.
Ramjets providing spin.
So, look up what a human eye can theoretically resolve and the rest is math
It’s actually surprisingly easy to see, just look down.
*Millions* of Earths in volume? Approximately 3k Earths could fit in the area of the moon’s revolution. Assuming the ring planet’s thickness is the same as the moon, it would look like a narrow pin stripe where not in shadow and *maybe* visible during the day.
What kind of never played Halo rage bait is this?
I mean, you can in halo, and that’s a pretty accurate documentary /s
But yeah you should be able to, similarly to how you’d see rings of a planet
From some time back… http://news.povray.org/povray.binaries.images/thread/%3Cweb.4360929f30852916731f01d10%40news.povray.org%3E/?mtop=10
That thread does a rendering of what you would see.
One of the trigonometry things that is of interest to some is that the angular size of the night and day parts of the arch of heaven are equal sized no matter how far away.
However, you wouldn’t be able to see the curvature of the ring at „regular“ distances. Consider that there’s a 1:1 map of Earth in the ocean on there. We can’t see the curvature of the Earth easily… Ringworld has less curvature than the Earth does.
Not on a Niven-style ring world. An earth-like atmosphere will turn everything into a blue-green haze after about 250 miles, less with dust and other such. The curvature at that distance won’t be noticeable. It would look like a flat world with a very thin arc rising in the distance.

This thread has links to some renders
Niven said the locals called it the arch of heaven. One character was chasing the base of the arch.
A large enough ring world would have an atmosphere thick enough to obscure the other side, and only visible if you fly above the clouds.
Ring-deniers would be real
Coincidentally just watched this:
