: The discs are centered on the orbit of the parent planet, and presumably rotating at the same frequency as the parent planet's orbit. That means the inner edge of each disc is going slower than you'd need to orbit the Sun at that distance, and the outer edge faster. If you moved inward from the original planet's orbit, the Sun's gravity would pull you in, but when you crossed the boundary to the next disc, you'd get flung back outward.[[Special:Contributions/162.158.62.61|162.158.62.61]] 19:58, 15 March 2023 (UTC) | : The discs are centered on the orbit of the parent planet, and presumably rotating at the same frequency as the parent planet's orbit.

::No Each planet fills out the space within their orbit into the next planet. Easy to see as the outer edge of Neptune's orbit is the same as with the planet flattened. There is a distance from Mercury to the Sun indicated. Maybe because it would melt if it got any closer? --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 20:03, 15 March 2023 (UTC) | ::No Each planet fills out the space within their orbit into the next planet.

:::First, they're rings not discs, but I'm skeptical of the math. And it looks to me like the ring's edges are halfway between the orbits, with Neptune extended outwards the same distance as halfway to Uranus's orbit.

:: Oh right, the Mars Climate Orbiter reference makes sense! I was wondering why Randall would mix imperial and metric units like that. No sane physicist would do that, especially not Randall.

If the planets of the solar system were to become disks centered on the respective planet's current orbit, how do we deal with the different orbital eccentricities? For example, per That Other Wiki, Venus has an orbital eccentricity of 0.006772, Earth has 0.0167086, and Mars has 0.0934. Not to mention Neptune's 0.008678 and Pluto's 0.2488; Pluto's orbit actually crosses Neptune's. Surely that would cause issues with the disks?

:Ahh yes, the classic cubic-bearing. Just what we need in this planetary ring system we've created. Since Randall elects to eschew spheres for the planets, let's go all in and refuse them for the bearings as well. Bravo. ;-) [[User:Iggynelix|Iggynelix]] ([[User talk:Iggynelix|talk]]) 12:40-12:47, 16 March 2023 (UTC) <!-- re'signed' to reflect how it now has separation from the previously following continuation --> | :Ahh yes, the classic cubic-bearing.

I don't know if there's a non spoilery-way to mention that there are similar ideas explored in the novel ''Death's End'' by Liu Cixin.

What would even happen here? Would the rings collapse into planets again? Where will the atmospheres go? Are the rings a uniform material like rock or many small pebbles? What happens at the borders? Would i be squished or will all life still be intact? If i a squished, do i have to put up with my worst enemy next to me? Will it be like the flat skins from //All Tomorrows//? Will i die? I expect to see this in «What If 2» coming out 13th october. [[Special:Contributions/172.68.134.38|172.68.134.38]] 14:31, 16 March 2023 (UTC) | What would even happen here?
