The thing that I thought was weird was that he explained that electrons orbit until they change shell.

I didn't think that's how they work. I thought they exist as a field of possibility, they don't actually "orbit" shit. They go from point A to point C, but they do not pass through area B in order to do so. So even within their own shell, they're magical little things. Which is a different model. On the show it's like they're mini solar systems and you can draw some parallels to gravity. Even though he says, "This is not gravity at all", that IS the inference you draw from just looking at the model. On other, more in depth, lectures I've watched about them it's more like they're completely WTF.

But complete WTF might not have been exactly the desired level of detail. It's strange enough that they teleport around interacting with light. And I suppose that's the entire point (beyond the history) -- here there be magic shit.

p.s. I already knew everything

Here's a mini lecture on what an atom looks like if you all are interested (it doesn't look like how it's portrayed in the show):

Neph was the literally the only person who came in here saying they knew it already. Everyone else has posted "I didn't know this" or "I never knew". Bunch arrogant bastards in here saying they learned shit. How dare they?

I didn't come in this thread for awhile because I missed the first few episodes, so after I watched a few I came to check it out and there was a lot of "I am so smart, I knew all of this already" until someone called it out that we don't fucking care and you look like an idiot having to post that here to reassure yourself in front of us. After that, I started seeing a lot of "cool stuff, I didn't know that".

On Netflix- The Inexplicable Universe with Neil Degrasse Tyson. He basically goes into way more detail on things touched on in The Cosmos.

Finally got around to watching the newest episode last night. Completely mind blowing. Surprised they didn't even try and touch the whole paradox of "Light is a wave and also a particle" because I was wondering how they explain that. I had absolutely no idea we identified cosmic items using their light spectrum. Mind blowing. Also it is hilarious how it seems a ton of these experiments stumbled onto things accidentally. Like the guy just putting his control outside of the visible light spectrum but in the infra-red spectrum. How long would it have taken us to discover the non-visible spectrum had he just put his thermometer in a different part of the room for control?

Hopefully there will be an episode explaining quantum weirdness. Like the two-slit experiment, Schrodinger's cat, many-worlds interpretation (quantum suicide experiment!), etc.

Can anyone clarify the whole jumping stuff again inside the atom. Was he talking about photons or electrons? Because I was under the assumption that the electrons kind of kept their same orbits and it was 2 on the inner ring, 6, 10 and so on. So I wasn't quite sure how the jumping works. But I guess I don't know much about photons if that is what he was talking about.

i found that information amazing i didn't know that electrons go in and out of existence. That is so fucking awesome something to nothing and back to something. Is it possible the electron is teleporting and not going in and out of existence?

I'm not sure if anyone really knows why the phenomena occurs right now. Assuming matter cannot be created nor destroyed it has to do something more akin to teleportation than simply going out of existence and emerging elsewhere. Would be nuts in a few hundred years we learn the phenomena and can blow it up from the quantum scale to the normal scale.

The underlying physics is really fucking complicated, but no they aren't teleporting. Electrons are actually being destroyed and created. Keep in mind that at the quantum scale the boundary between matter and energy is a lot looser. Because formostfundamental particles the masses involved are so small and comparatively a lot of energy is in the system. Electrons specifically do not have a mass of their own, but instead gain it through the interaction with the Higgs field.

edit: Clarification. Some fundamental particles are kind of hefty like the tau lepton, but they form from a shit ton of energy getting together for a party and then quickly decay. Like at the LHC.

The Higgs field, incidentally, accounts for a tiny percentage of the mass of matter. As example of how much energy there is compared to matter in these quatum systems: The constituent quarks of a proton make up about 1% of its mass. The rest of the mass comes from the energy keeping those quarks bound together in the gluon field.

I felt like I had learned a lot after this episode of Cosmos, but now I feel dumb again

Have they proved the Higgs field exists or is it a concept that just makes a bunch of theories and math work out correctly but cannot currently be proven?

Doesn't the Higgs boson prove the higgs field?

No clue thats why I'm asking. I know CERN announced they found the Higgs particle but I thought I was reading somewhere some scientists were disputing the claim. Maybe not.

Pretty impressive for a Kentuckyian.
