What if planets were not (nearly) spherical but rather torus/donut shaped? Topics discussed: types of tori, stability of torus planets, gravity vs centrifugal force, curvature, tidal forces, seasons and day/night cycles, climate, hurricanes, coriolis forces, tectonics, internal heating, moons, and the four color theorem.

Well, actually, I think it wouldn't be very strong, because our magnetic field is created mostly by a large mass of iron rich magma rotating in the Earth's core(I heard something about an experiment where they use a pretty huge ball of molten sodium to simulate that, which is extremely dangerous because sodium really likes to catch fire and it does even more so when in contact with water) Anyway, because the torus planet doesn't have that I think it wouldn't have a strong magnetic field; but idk, maybe a big ring is better than a small ball? I do think the magnetic field is most interesting in the hole

Millad Bahrami actually it would be easier. You wouldn't have to deal with any projection system at the poles (in video games you often see pinched poles on planets) For a torus, you just unroll it into a cyllinder, then unroll the cyllinder. The only change here is that whenever you move above the "top" of your map, you would automatically appear at the bottom. Unlike a spherical map where you have to calculate where you would be on a rectangular projection. Just think about it, would it be easier to cut apart a soccer ball into a rectangle, or to unroll a paper towel roll?
@Alienturnedhuman
@Alienturnedhuman 9 жыл бұрын
Millad Bahrami Actually, it wouldn't - a torus can be mapped to a rectangle as well, only where on a rectangular projection of a sphere one edge joins to the other (east and west on most maps of the Earth), both edges join together on the map of a torus. This means that on a rectangular map of a torus, with the bottom edge being south, the top edge would also be south, the middle would be north, and the 25% / 75% distances would be the outside / inside equators. However unlike maps of Earth it would be more complicated to work out distances, as both equators would appear the same size whereas the inside equator is shorter than the outside one. However, as a rectangular map of the Earth already has this problem (ie, latitudes get shorter the further away from the equator you get but appear the same length on a map) - on a torus map it would just mean that one half of the map had latitudes decreasing as you move away from the equator and the others would have it increasing, with the poles being equal in length.

Asteroid Ventures Actually, you do need different projections for torus shaped worlds as the planet would be a 3 dimensional shape being shown in a 2D space. A rectangular projection would be one option, but then you would also have others, such as shape preserving projections and equidistant projections. Though I agree that mapping a torus is definitely easier than mapping a sphere

You're back!! A thing to note though "Centrifugal Force" doesn't actually exist.. There's a thing called the "Centripetal Force" which works in the opposite direction. An example: Say you have a rock tied to a rope, you now start swinging the rock in a big circle, faster and faster. You can feel the rock pulling harder on the rope the faster you go, as if there was a force dragging it out. This perceived force is what you call centrifugal. The reality is that there is no force acting outward, but rather one acting inward, one keeping the rock from flying away. If at any point during the swinging the rope were to snap, the rock would fly off in a direction perpendicular to the rope. What you feel in the rope is actually the rope pulling back on the rock, constantly resisting it flying away, changing its direction as it goes along. (I even provided an illustration: imgur.com/CgrtUB8 ) The centripetal force translates to everything having an orbit, in the case of solar system, rather than it being a rope holding a rock in place, it's gravity (and a bigger rock). This is also why the faster a planet spins, the more it bulges in the middle, the rotation is counteracting the gravity more in the place it spins the fastest: The equator So in fact, on your torus diagram, you could just have left off the blue arrows, as the gravity would be what would keep the torus from falling apart; but the rotation would also be what would keep the gravity from crushing it into a sphere.

Nikolaj Lepka I keep seeing this sort of comment everywhere... Yes it's a phantom force, but it still exists, as long as you are in a rotating reference frame. If you're gonna say that centrifugal forces aren't real, then you must think the same for gravity, as in general relativity, it is nothing but a phantom force caused by the curvature of space-time.

This video was really well put together, kudos! I'm loving going through all these and making my world as real and well thought out as I can. But it got me thinking, what about an inverted Saturn? In other words, some sort of non terrestrial body at the center that's surrounded by a terrestrial torus or "donut" shape that's solid and inhabitable. Would that be theoretically possible? If not, what is preventing that from being the case? Judging from this video, I'd imagine this torus would have to be spinning incredibly quickly and the body at the certain would have to be unusual in some way. Perhaps a wormhole or some other kind of space-based anomaly.

What sort of apocalyptic setting could I write?

In addition, a ringworld's "gravity" is provided solely by centrifugal force, whereas a torusworld's gravity is part real gravity, part centrifugal force gravity.

Hey Edgar! I've got an idea for a story world thats a series of concentric rings, and I was wondering if you had any thoughts on the physics of such a place? The world would be held together in stable relative positions with in-world magic, but aside from that I've been trying to figure out how a disk-shaped gravity would affect oceans (I'm thinking solid-mineral rings and bodies of water held in between them) and lunar bodies. The story will take place over several millennia, so I need to work out the long term physics of the body's orbit, day/night cycle, and tidal forces both with and without a lunar body. Any advice you can give is greatly appreciated! Thanks, -Redal-

Physicist here, if you want something literally "cool" to happen on the inside of the torus, either don't tilt the rotational axis at all or make it so that some of the inside is "hidden" behind the opposing half of the torus. Because, if we assume a slightly tilted axis of rotation, the "poles" would behave "normally", i.e. "just as on earth", but if you move away, towards the inner equator, you'd pass through a zone that would experience polar night half a year, and would then experience a day-night cycle with days becoming ever so slightly longer, eventually reaching a 12 hour (i.e. half cycle) day during the "summer solset" before they'd be getting shorter, while even closer to the inner equator you'd actually experience no daylight whatsoever at ALL. Because while your "half" of the torus is in the front, the daylight is obscured by the landmass between you and the sun (just light night on earth), but 12 hours later, when you are at the backside, facing towards the sun, well, the other half of the torus is obscuring its light, meaning you don't get any light AT ALL. So the warmest and brightest part of the torus inner side would be the poles, the "temperate zones" would experience polar night for half a year and slowly longer getting days not surpassing the 12 hour mark for the other half of the year, with the "tropics" never receiving any daylight whatsoever.

Awesome! My alien species (best compared to the Forerunners from Halo) actually came from a toroid called L'Hav. Probably the most interesting part is the moon, L'Kyr, which orbits in a figure-8 pattern through the "donut hole". It's a city moon with a ton of geothermal plants as well that beam excess power back to L'Hav with microwave guns. Crazy stuffs!

1. How big would a donut planet need to be to have an AVERAGE gravity the same as Earths? 2. What is the surface area of the planet compared to an Earth of the same mass? Is there less surface area in total?

Have you ever looked at the Wikipedia page of a toroidal planet and thought "Man, I wish I knew this much about my fictional torus planet."? What am I saying, of course you have, let's do this.

There is no way for a moon to exist inside the planet's hole because it would get pulled outward by the planet around it and become a pancake expanding outward towards the donut planet's inner side until crashing into it, meaning that an already unstable location for a moon would also tear it apart by tidal forces.

On the farest outside of the planet, where the speed from the rotation is the highest, could there be like negative gravity due to the coriolis effect and the rapid spin and... would this mean that if you go there you would simply fall off or (better) be thrown off the planet? It would be funny to know xD

all mass produces gravity, if you are on the inner ring the gravity produced by the mass below you would be added to the gravity produced by centrifugal force. gravity does not emanate from the center of objects, it emanates from mass. the interior ring's gravity would most likely be the place with the highest gravity.

Since they're apparently near-impossible by natural formation, I assume it would be much more possible for a super advanced alien race to create such a world. That, or a far future humanity.

Would you even be able to stand on the inner surface of the donut? Gravity acts toward the center of mass, so you would fall off of the inner surface towards the empty middle point right?
@kumbi8368
@kumbi8368 8 жыл бұрын
No, you would not. Because the force which is keeping the world in the shape of a torus is the same force that would keep you standing firmly on the inner rim. Centrifugal force. In the case where the earth isn't spinning very fast, yes, not only you but the entire planet would gravitate towards the empty middle point and form a sphere.

But wouldn't gravity be super weird there? To make it possible to stand in the hole, there would have to be a really weird gravitational pull through the the ring if this planet, which would probably sometimes cause yourself to get randomly pulled back and forth, and side to side. But, if the gravitational pull comes from the center of the planet, where there is space, wouldn't that mean stepping too close would send you flying to space? Or am I just being stupid?
