Astronomers discovered an "impossible" ring around the dwarf planet Quaoar in the Kuiper belt beyond Neptune's orbit. Quaoar's ring orbits far outside of its Roche limit which is thought to be the maximum distance planetary rings can be stable.

It is a magnetized planet with a magnetic field. The standard mass function is wrong, it uses, the Newtonian model. The ring is not due to busted up moons but is a standard plasma ring current which traps charged particles in it. The ring radius varies with magnetic flux density. The larger the magnetic flux density the tighter the radius. The smaller the magnetic flux density the larger the radius.

I've missed your voice, Christian. I'm glad you're feeling more normal again. I did see your explanation in the early patreon messages, but I didn't have time to respond. Sorry. I love Quaoar, I'm absolutely convinced that it's density is far less than we know. I'm not saying in comparison to gas giants densities, however far less dense than Earth for example as a terrestrial entity, and the rings could be expanding away from its gravity. Also its more likely to be shaped like a potato I would imagine.... a very ugly potato.🥔 Either this or the rings are a real life Halo from an Alien world!!! Good to see you again.

@jimwinchester339 Год назад

The simplest explanation is that the rings didn't form by a single moonlet drifting inside the Roche limit. It could have formed by a moonlet colliding with another object (pulverizing it). The outer solar system evidently abounds with very close objects (that ultimately usually form contact binaries) - - but sometimes not: if they're too far away, then when they finally come together [with too much momentum] they can annihilate each other.

@timothy8426 Год назад

Since mass neutralizes resistance within. Proximity mass of lesser energy is repelled towards the weakest point of resistance. Forward momentum is a factor to repulsion. Spheres are proof of pressure in equalization of resistance. Circulation around greater mass of neutralized resistance within accumulates proximity mass of greater resistance to mass. Resistance in smaller mass is repelled towards the weakest point of resistance, which is the greater neutralized mass of weaker resistance. Galaxies are formed by this process. Proximity mass is repelled towards the weakest point of resistance. Mass occupies space as space itself neutralizes resistance within as force of pressure known as weight. Table of elements proves hypothesis. Hydrogen under extreme pressure expands cold resistance into equalization of pressure and expands into helium. More pressure exerted within, more pressure exerted without. Spheres are equalization of pressure. Force of pressure. The nucleus of atoms expands cold resistance into equalization of pressure exerted on it. Hydrogen expands into helium. More pressure exerted, more repulsion equalization. Decay is heat loss. Accumulation of thermaldynamics, equalization of resistance to thermaldynamics pressure increases. Hydrogen expands into helium.

@DarkVoidIII Год назад

As for the rings themselves, perhaps the satellite orbiting Quaoar has an influence on the rings? Perhaps the JWST is taking bad readings of distance, as I have noticed there are some videos claiming it is seeing galaxies that are too large to exist. Possibilities abound.

@utah133 Год назад

The mass of the ring material would affect its characteristics, I'd think. Am I right or wrong? We might have seen them during their brief existence as well, after some sort of an impact event.

It must be a very dense planet. Less density in the ring debris could also cause that, but I'd assume that less dense ring debris would more easily be stripped out of the ring by the gravity of other objects.

@malachiXX Год назад

I always enjoy discovering something we can't immediately explain. Then the detractors try to deny any explanation stating "What are the odds of that happening?" I like the part when I can say "The odds aren't important, when you have spent 4.6 billion years trying and possibly failing. The fact that we fouind it is enough to give us a reason to try to explain it" People always try to say the chances of that happening are less than 1 in a billion, or some such fantastical relationship. I say, when you've been doing this for billions of years and trying with billions of particles and we have only found 1 so far....the likelyhood is probably much less than you think. ☺

The fact we found the largest Star in the observable Universe as it's about to blow is beyond likely as well. that had the tech to detect Oumuamua as it flew by on it's one trip through our Solarsystem. that we had the Carrington effect just as we started using electricity and telegraphs that it could disrupt And that the Moon fits right in front of the sun in eclipses. So far out and so stable, this could be a base or space station built round that body and rotating to create gravity for the Inhabitants. Thick and thin parts could be structures or semi transparent parts. That stone could have been a lot bigger and they mined it for the materials to build a 10 -20 kilometer ring base making the ring look too far out. That's a lot of material to build something that big. Interesting for sure.

@Eventlesstew Год назад

Im no expert, but my theory on how Quaoar’s rings could’ve formed is from an impact of course, but the rings could’ve initially been in the Roche limit before it was dragged outwards past the Roche limit by Weywot, Quaoar’s moon. If these rings cannot be outside the Roche limit because they would form back into a moon or something, either they would’ve been dragged out a bit closer to the CE/AD (like in about 300 or 50 Million years ago) or the asteroids just cannot do that like how the Asteroid belt is formed of objects that cannot collide into one planet. Like I said before, I’m no expert on Solar system formation so take this with some salt.

@fredwood1490 Год назад

Usually, such rings are maintained by shepherd moons but shepherd moons obey the same laws as rings so they shouldn't be there either. Could the dwarf be super heavy, like a very dense piece of the super nova that created this section of the solar System?

@guidedmeditation2396 Год назад

Of course they should be possible. The gravity of the dielectric inertia plane exists with all toroidal dual pole magnetic fields. They are universal with planets, stars, moons, galaxies and even people. Every planet in our solar system has one kind of belt or another as well. This gravity disc plan is what makes the trillions of galaxies disc shaped, it shapes the disc like rings of Saturn and also makes the planets in our solar system follow an orbit within the disc like gravity plane from our sun's magnetic field. It is zero surprise that a dwarf planet might have rings. Look up the asteroid belt surrounding our Earth.
