I've often thought about the general similarity of the structure of an atom, particles orbiting a central nucleus, and the structure of our solar system.
 
Um, no. The planets in the solar system orbit pretty much in a plane, the ecliptic. Atoms are more of a sphere. Because one is driven by gravity and the other one aint.

Of course. Many different dynamics.
 
Physics of the very large, vs physics of the very small?

Fuck me, where did that come from?
 
Similar to the way flies and mosquitoes orbit Conager's bald head.

Someone's trying really hard to look smart after all of the incredibly stupid shit he's posted in the past. :cool:
 
If you look really, really close you can see a few of the universes inside of an electron. :)
 
Also, electrons have the same mass. Just like planets.

What do you mean by 'just like planets', or was it sarcastic?

I've thought about the concept a lot too, but there are key differences between the micro and macro scale. As stated before, the force acting on planets and satellites is due to gravity, while those acting on electrons is the electromagnetic force. If we had a grand unifying theory then maybe they could be directly related in some way, but I'm pretty sure gravity is the main issue with GUT (I could be wrong, its been a while since I looked at this stuff). Also why theres an orbital plane versus how electrons orbit.

That being said, I've always wondered about neutron stars. Its something I haven't looked up, but I wonder if they act similarly to a very large atom for all intents and purposes, except instead of the strong nuclear force its gravity holding it together. Or maybe it IS strong nuclear forces and I just don't know enough. Is the density similar? Is the force that holds them together similar?
 
Just think if you had a binary star system. One star was a neutron star and one was a proton star. Woah....
 
But, as David Berlinski asks, what compels the electron to orbit the nucleus? Even at absolute zero, this happens. Why?

Electromagnetism. The various shell orbits correspond to different energy levels.
 
Yeah, the "planetary" model of atom, while descriptive at elementary school level, is long outdated.

Elections rather form probabilistic clouds than orbits, and while some energy levels are spherical, others aren't. And that's before the craziness of quantum world where particles move between allowed states separated by exclusion states, without even necessarily really moving, but rather popping in and out of existence.

I love the thought experiment, but I don't think a proton star could physically exist, or at least I've never heard of it before. I imagine the insane repulsion due to their positive forces would rip it apart before it could even form. Although, most stars ARE just hydrogen (protons). I don't think they're the same though, but I'm not sure. Interesting idea!

We've never achieved absolute zero, so I'm assuming its backed by math that electrons would orbit? That should be due to electromagnetic forces. But if you didn't have any energy, i.e. absolute zero, would you still have any kind of force at all? Without any energy, the particle would have 0 mass, and I imagine wouldn't have any charge either, so there would be neither gravity or electromagnetism.

Wait, I just thought of this (sorry, I like to ramble): if you had a 0 mass particle, would gravity not effect it at all? I'm thinking simple Newtonian math here, so I'm sure a more accurate description may give a different result, but if both masses are combined to get your force value and one is zero then... F = 0 too?

That might explain the electron being bound to the nucleus, but it doesn't explain their movement, especially at 0 degK.

Does it ever? It exists in a cloud form in the nucleus, it isn't at any particular place but everywhere where it's allowed to be all at one, unless knocked out.
 
My second favorite episode of WKRP is the one where Venus teaches a kid about the atom in terms he understands from the street. It's cheesy but accurate and it works in it's own way.
 
The way they teach it in school, it's like a beautiful miniature version. You could imagine our galaxy as just another atom in some even larger galaxy... things to blow your mind when you're stoned.

In reality, is the electron even there? Or everywhere? It's only probably anywhere until it's observed, and then suddenly it was there all along. There's a theory that the universe could contain just the one electron, being everywhere at every time, and the ridiculous part is that it's not that ridiculous. Things to make your head hurt when you're sober.

The more you learn, the less you understand. Every new answer supplies a thousand new questions.

Robins navigate using quantum entanglement, with the electrons in their eyeballs. Shit like that makes the mysteries of space look pretty basic.
