If you have one moon then you get gaps when the orbital period of the debris is a rational fraction of the moon&#39;s. Simpler fractions making larger gaps, so the base of the larger circles are the larger gaps. <br/>So the thickest rings should be the periods hardest to approximate by a rational multiple of the moon&#39;s, such as phi. They&#39;re least resonant.<br/><br/>Orbital radius having a simple relationship with orbital period. 2025-05-11T11:46:21Z https://yabu.me/nevent1qqstd73yzf3fynczgt472zxw4ulga3x3qhvutf0lf5e5tlz2hfnk00qzyz2fg0c8kypnjvzt4cutcna288925s44q5zvc4j3qfkfw0txhjf4zc8wpyw In reply to <a href='/nevent1qqs2m89h8gvdpd7jvayesg3a2r7xakc8e2ut60488skq74styputspsp08ckz'>nevent1q…8ckz</a><br/>_________________________<br/><br/>Scotland also has nice laws on the right to roam <a href="https://www.gov.scot/policies/landscape-and-outdoor-access/public-access-to-land/">https://www.gov.scot/policies/landscape-and-outdoor-access/public-access-to-land/</a> 2025-05-04T04:46:23Z https://yabu.me/nevent1qqsdhwe7stdpyhcx256s0rmk7g9mqph4yrvgzd592lg07865ee37sqczyz2fg0c8kypnjvzt4cutcna288925s44q5zvc4j3qfkfw0txhjf4z5x764a In reply to <a href='/nevent1qqsxhj6r2yjglkpq66j48ze9r8r9254ydc9pvwlvfh67027z7mtf7fg94g90s'>nevent1q…g90s</a><br/>_________________________<br/><br/>Bananaman, &#34;the muscles of 20 men and the mind of 20 muscles&#34;<br/>It&#39;s a funny parody of superheroes, he&#39;s missing a few marbles.

You can construct a dome such that you can roll a ball up it and it comes to a halt at the top in finite time. This is perfectly believable to me, and is I&#39;m sure a proven fact.<br/><br/>The problem is that information is lost, the historical state cannot be reconstructed from the stationary ball at the top. <br/><br/>There are similar problems in Newton&#39;s laws, but as far as I know they are all non-general (have measure 0 in state space) so require an infinitely precise setup. So they don&#39;t affect real-world predictions. 2024-12-27T00:08:41Z https://yabu.me/nevent1qqspwldupdhdslxryg4yzlxzlwjc3fq52zvvp47lw8uhvtxhqfcv94czyz2fg0c8kypnjvzt4cutcna288925s44q5zvc4j3qfkfw0txhjf4zu4u2de In reply to <a href='/nevent1qqsdzau7af93hzxrhx6xytr0jn4yny82sqjq368svrp442e2e7ped6qdpgkw5'>nevent1q…gkw5</a><br/>_________________________<br/><br/>heh heh, mmm yes, I&#39;ll just get on that. 2024-11-27T05:13:18Z https://yabu.me/nevent1qqstladjwq6tnr24fpzmw0y8j2jz6vtncvxu78s6ewlckxpe09veg4szyz2fg0c8kypnjvzt4cutcna288925s44q5zvc4j3qfkfw0txhjf4z7l32tv In reply to <a href='/nevent1qqs2k35p6ec6wa9dc26pgwry9yrd4a4gsxradyp07yerzj80lj0w5dq7lfvrr'>nevent1q…fvrr</a><br/>_________________________<br/><br/>seems to me that this should be true of any fractal sponge.<br/>And any fractal foam holds any general 2D surface (which can branch). 2024-11-27T05:02:06Z https://yabu.me/nevent1qqsqzdvptv2mkef8lp4dfm7hxpunnm8mg9nqyys6spwqgn5urnxpmcczyz2fg0c8kypnjvzt4cutcna288925s44q5zvc4j3qfkfw0txhjf4z4dtzjr In reply to <a href='/nevent1qqs9dnp47sxsa5pjvkpj0mqvfamshju3atlzjs0adpl0fa8t9akmywg067y40'>nevent1q…7y40</a><br/>_________________________<br/><br/>It&#39;s one of those &#39;Why do this rather than feed the starving?&#39; sort of questions that could be asked about pretty much any profession or activity that we do. <br/><br/>Perhaps the answer has to do with diversity.
