The development of astronomy in that system would get stuck after Keplerβ€”Newton’s laws would be dismissed since they couldn't explain the orbital resonances.

. earth.com

. article about 6 planets, neither of them is Earth

What a disappointment

Meanwhile our solar system is a mess. Rings and tilts and giant moons and all. But Jupiter has that sort of stable mathematically pleasing balance as well, so I’ve always assumed this is the β€œideal” orbital state; all the planets have reached stable equilibrium and nothing has interfered. It just makes sense that that’s how things default.

I learned recently that Neptune and Pluto have orbital resonance, with a 2:3 ratio of orbital periods.

It's cool, but I wish they had a gif or something with the article

[–] davidgro 10 points 4 days ago (1 children)

It does link to another article with one Here (It's musical even)

Yes this is the source.! Very good visuals.

This is a Bobiverse thing, no? Heavens gate maybe? I remember one of the systems found with like perfectly spaced planets moving harmoniously. Neat, great share, thanks!

aliens did it because alien programmers said it would make coming up with a universal time coordination easier. spoiler: they were wrong

And now there's another standard.

These planets all have incredibly short "years". The outermost only takes 55 earth days to complete one orbit. I suspect that this means they are also all very close to their star. That would explain why there is such harmony as the star is easily the only and/or largest gravitational influence on them.

Hol' up.

Mathematics tries to describe our world. So ... Essentially EVERYTHING is mathematically described to the extent of our knowledge.....

What is not mathematical? Human thought? Human behaviour? Even those are described but not perfectly.

So even if we say something is "perfect" it is only to the maximum observable human extent and limits.

Either everything is perfect or nothing is perfect or it is somewhere inbetween.

Am I in lemmy shitpost or something?

Mathematically clean and tidy would be a better description. This system is particularly close to the natural harmonics that either occur when planets form, or that planetary systems tend towards.

It's akin to watching a group of metronomes move into sync. Mathematically, it's not that special. To us monkeys, that particular pattern feels a lot better and cleaner.

Scientifically, it's quite useful. By judging the age of the system, we can tell a lot about early formation and planetary movements. As the article mentions, it's likely that planets form in such a resonance, then get knocked into chaotic orbits. However that's not been tested. This system would let us test some of our models against reality.

Mathematics doesn't try anything. It's abstract. Humans try to fit mathematics to real world phenomena, often with great success, but we don't know why things seem to work out, only that they do.

Whether it means the universe is fundamentally mathematical is a bigger question than for both science and philosophy combined, and so mathematics is merely a useful modelling tool until we know for certain. (And we might never know.)

The "perfect" mathematics in this case is that this planetary system has all planets in what's called resonance, that is, the orbit time of the planets is in some relatively simple integer ratio. e.g. the innermost planet might go around twice for every once of the next furthest out (2:1), or three times for every two (3:2), etc.

The article doesn't give the ratios, but there is a tendency for planetary resonances to self-reinforce, that is, once nearby planets in non-resonant motion get close to an orbital resonance, there is a tendency that their orbit speeds will shift towards that resonance over time, and outside interference is usually needed to break a resonance once it has been set up.

There was no grand mathematical plan, only an emergent phenomenon.

Maybe this system has ended up with 32:16:8:4:2:1. That would be neat.

You're thinking of physics.

perfect mathematical harmony = engineered, the aliens did it, obviously
