The atom model with the electrons going around the nucleus, is inspired by the solar system. The better model doesn't look anything alike. This is a naturalistic circular fallacy
If atoms were like the solar system, all of the electron orbits would lose energy and decay by emitting electromagnetic radiation.
The same type of decay does occur in the solar system as the planets emit gravitational radiation, but the decay rate is so miniscule we can't really detect it.
Could you explain what you mean by "emitting gravitational radiation"? Gravity is how we perceive distortions in spacetime, the strength of which being determined by the mass of the objects. I understand that orbits can "decay", but that is not the same as radioactive decay.
Electrons do orbit like planets in the solar system however they're also waves. Which is what gives the set radii they can orbit at and keeps it all stable. The orbits can and do change due to the emission or absorption of certain quanta of radiation.
So saying like is fine. It's not an exact description but more of a simile to help understanding. They do orbit like a solar system. Saying electrons orbit the same as a solar system would be incorrect. That's when the maths doesn't work and the electrons orbit would decay.
Look, I'm not saying our universe exists as a node in an infinite fractal of repeating universes, but one of these is the largest structure we can see and another is the smallest:
I think the top is the small one because you zoom in really far on small things in rectangles. And the bottom is the universe because it's a distorted view of a sphere, like our full view around us.
There was a guy on the net years ago who claimed that the entire universe is an electron on a plutonium atom. He made a religion out of it, wrote hymns to the atom (or, more precisely, changed the words of Christian hymns, clumsily fitting in references to plutonium atoms) and even legally changed his name to Archimedes Plutonium.
I always find it fascinating how specific those theories become. Want to believe that our universe is just some sort of quark in a bigger universe we can't know anything about? Fine. Doesn't make terribly much sense, but what does at that scale anyway? But then going on and being sure that that bigger thing must be Plutonium? Why? How?
There was an episode of PBS Space Time on the holographic principle in general recently, and I believe they've also discussed the black hole thing as well.
If it's a block hole, it doesn't really matter. A black hole is not more dangerous than a planet with the same mass, it has the same gravity. The only difference is that it's much tinier. If planet 9 is a black hole, it's so small that Sun has stronger gravity (and bigger mass), meaning it's bound to rotate around the Sun the same way every other large body in the Solar system is.
Planet 9 maybe is or isn't a primordial black hole and it won't hurt you.
IIRC, isn't it closer to a white hole, what with expansion? If you were far enough away, you cannot reach 'there' vs being guaranteed to reach 'there' like a black hole. Though really, it's neither. Just curved spacetime.
The fact we think of white holes and black holes as separate entities just goes to show our great lack of understanding of spacetime.
I mean, Schwarzschild radius shows that for a medium of constant density (and on a large scale, Universe is fairly uniform) there is an upper limit of a radius of a ball comprised of said medium above which it will form an event horizon.
Which means that an infinite universe of non-zero density is either a bloody paradox (spend a minute deciding where exactly event horizons should form and whether there will be gaps), or our understanding of gravity and spacetime breaks on ginormous scales just as it does on micro ones.
PS: I have seen no physicists talk about this, so there’s a good chance that there’s a simple resolution to the problem and I’m just stupid.
I've always liked this idea. Like, everything just repeats as infinitum whether you look smaller and smaller or bigger and bigger. The universe is just one of those fractal image kaleidoscopes.
I mean when I'm on Delta-8 that's how I see the world, sometimes on shrooms too. Everything is just zooming out and zooming in, and it's all just.... the same thing, but not the same time... and all of it is turning to face God, but they only see the others turning to face God, infinitely everything looking for the source, but we can only see the other universes looking for God....
It'a... circular, I think it's going somewhere but it doesn't.
I've been into gut health lately and I was thinking what if we are the microorganisms inside a bigger beings gut? This planet is just one part of it and in order for the universe to have a healthy gut we would have to terra form the planets and make healthy worlds. (I don't think we will actually do that. We are more likely to mine every other planet)
The universe's gut now looks like the typical American diet gut with ultra processed foods and not enough fiber/fermented foods.
This planet is just one part of it and in order for the universe to have a healthy gut we would have to terra form the planets and make healthy worlds.

I want to question the assumption that an increase of Earth-like planets would be better than the current state of the universe.
The idea that the current state of the universe is unhealthy, and needs us to save it by increasing homogeneity by altering other planets to look more like ours..
I'm just gonna say it.
It's eerily reminiscent of the colonizers' mindset of "saving the world by making it more like us"
It comes from the assumption that others' current state of being is inferior to ours, and need to be fixed, by us assimilating then into our, superior, state of being. It comes from an assumption that there exists inferior and superior states at all, and that superior states of being should be strived towards. Rather than assuming that diversity is better than homogeneity, and different states of being are neither inferior or superior, they simply are.
I question the idea that us changing the universe to resemble us, would be superior to the current state of the universe
I had this thought as a kid. But I thought it was neat that we might be part of an atom of some larger molecule. Didn't keep me awake. I had other trauma keeping me awake, like going to school.
You just need to know what happens to the elements on the periodic table that have the highest atomic weights. Here's the article for Lawrencium give that a quick read through and then try to figure out why the universe is almost certainly not a very large atom as we define it.
It is in the right groups. Sort of thing you can find talked about at flat earther meetings all over the globe, UFO enthusiasts if you can get a word in to ask and in Christian science journals.
because it only seems believable if you're using an outdated and simplified model for atoms, and forget about the fact that atoms are also made up of protons/neutrons who are in turn made up of quarks, and the fact that there are a whole bunch of other fundamental particles that don't give a toss about atoms.
If you look at the more accurate electron cloud model it stops making sense to compare it to a solar system.
Now imagine if something... or someone... would poke our galaxy with an observation, and all the stars in the arms instantly collapsed into a single particle.
Doesn't take a scientist to think about. We learn in middle school, atoms are mostly empty space, we learn small electrons revolve around a larger nucleus. All it takes a little imagination to put two and two together.
