In some instances, circuits are connected to objects (stakes or pipes) that literally go into the ground. This dates back to telegraphs circuits, ~200 years ago. The terminology isn’t going to change; that it doesn’t make sense to one (or a few) people doesn’t carry much weight against something that’s been used for so long. ”Mass” is a term from mechanics, and I’d wager that a lot of people would be confused by its use in electrical descriptions. Especially in some scenarios where both were present and you wouldn’t know which mass was meant.

Gravity (split from A change in Gravity killed the dinosaurs!)
swansont replied to kba's topic in Speculations
What are the values of k1 and k2? How are they determined? How would you determine the force the sun exerts on the earth, and on the moon? Neither of these are asteroid impact or Deccan Traps. If you would answer questions instead of moving the goalposts, this might go better. -
Dynamic Gravity theory to explain dark matter, cosmic ray energy, etc.
swansont replied to kba's topic in Speculations
You don't have a theory. There is no model I can use to make specific predictions, and you haven't provided evidence that the idea is true. What you have is a guess that sounds good to you, but it doesn't look like there has been any critical analysis of it until now. -

Some wisdom about English I've read over the years: English was a language invented by Norman invaders to pick up Anglo-Saxon barmaids. It retains much of this character. --- Either from H. Beam Piper or Paul Drye's English professor Peter Newman English doesn't "pick up" loan words, it consciously stalks them. --- Andrew Moffatt-Vallance The problem with defending the purity of the English language is that the English language is as pure as a crib-house whore. We don't just borrow words; on occasion, English has pursued other languages down alleyways to beat them unconscious and rifle their pockets for new vocabulary. --- James D. Nicoll -

There are elements of quantum mechanics that can't be explained using classical mechanics, so your dynamic gravity can't explain quantum mechanics in these terms. It can't explain everything, but it can explain everything? You are making lots of promises, and yet you haven't delivered on any of them. Soon it will be time to put up or shut up. -
Gravity (split from A change in Gravity killed the dinosaurs!)
swansont replied to kba's topic in Speculations
That's one equation you need to show; the gravity on the moon is not the same as on earth. The trend of gravity varying from one planet to another is not obvious, other than being proportional to its mass. If you can't show this, then the notion of it varying is moot. Telling us what it isn't, isn't particularly helpful. Especially when "substance" typically means it is made of particles. Is there any other substance that isn't? So it's 1/r^2, which is what Newton's law already says. And Newtonian gravity explains almost all of what we observe (GR explains the small deviations from Newtonian gravity). So what does your conjecture bring to the table? If this is a correction, you should be able to point to phenomena that don't fit with Newtonian gravity. Same comment as above - what about these are unexplained, and how exactly (i.e. not hand-waving) does your idea fix this? This all seems consistent with the fallacy of personal incredulity - that because you don't understand something, nobody does. -

Yes, but perhaps you've had the experience of knowing something is A or B, but the topic is sufficiently esoteric, and encountered so infrequently that you can't remember which one is correct. (and then the 50/50/90 rule comes into play) I've had this happen to me on several topics -

"It's wrong" is the one that matters. All else is theatre As you see. But this requires expertise in geology and biology as well as physics. Are you, in fact, and expert in all of these fields? Or is it possible that you simply aren't aware of the mainstream science that accounts for each of these? -
Gravity (split from A change in Gravity killed the dinosaurs!)

Formulas, which allow for specific predictions. Explaining how it works is a start, but you need more detail. What are the details of how this substance gets from the sun to a planet? What happens when a body blocks the sun, or otherwise interrupts the flow of this substance? We've done experiments on how time changes owing to gravitational effects. Can you come up with the same formula based on this approach? This is unclear to me. It suggests that gravity of a planet/body only depends on its distance from the sun Which is no evidence, since that's already explained by mainstream science. You're getting way ahead of yourself. You can't explain anything without the underlying hypothesis being demonstrated. You have three different explanations here. Are they compatible with each other, or are you just using a shotgun approach, hoping that something in here is on target? -

swansont replied to kba's topic in Speculations
1. No, it doesn't. This is far too lacking in detail to make such a claim. 2. Who is CM? QM is far more nuanced than this. The basic model this corresponds to - the Bohr model - is incorrect. Even so, can you derive the energy levels of the hydrogen atom starting only with your material? Can you explain the Lamb shift with your "model"? The hyperfine splitting of the ground state of hydrogen? The fact that the ground state has no orbital angular momentum? -

Or maybe it's because he's not a lawyer. Every profession has its own nomenclature, and people outside of that profession won't be as well-versed in the language that is peculiar to it. As Peterkin notes, "quash" is likely one of those terms. -

At best this would be a (regional) dialect. Similar to someone “aksing” a question. I’m bothered by the British tendency to drop the “h” that starts a word, or drops an “r” at the end, etc. (oh, that’s not all Brits who do this? Imagine that!) I’d go with that, rather than assigning a motive without evidence. What we learn when we’re young is hard to change. Consider how some people can’t overcome this when they try to speak another language (“shibboleth” story from the Bible, or the stereotypical scene of a Japanese or Chinese speaker pronouncing “L” and substituting “R” e.g. “lollipop” as “rorrypop”) -

Yep. As I and others have repeatedly pointed out, there are a number of words where lay definitions and physics ones differ, sometimes significantly. (e.g. coincidence) I would hope that physicists, at least, would recognize this. -
You mean potatoes with copper and zinc electrodes jammed in them? The electricity comes from the metals. The potato is a salt bridge, conducting electricity. Not the source. https://www.smithsonianmag.com/innovation/a-potato-battery-can-light-up-a-room-for-over-a-month-180948260/ the potato is not, in and of itself, an energy source. What the potato does is simply help conduct electricity by acting as what’s called a salt-bridge between the the two metals, allowing the electron current to move freely across the wire to create electricity. Numerous fruits rich in electrolytes like bananas and strawberries can also form this chemical reaction. They're basically nature’s version of battery acid. (You can do the same thing just using salt water, if you build it right. Those plans are also somewhere out on the intertubes)

Dynamic Gravity theory to explain dark matter, cosmic ray energy, etc.
swansont replied to kba's topic in Speculations
Not sure where you're going with this. The energy of the electron states in e.g. a hydrogen atom is not the mass energy of the electron, it's the energy from the electrostatic interaction. The potential well is 13.6 eV deep for the ground state electron. In He+ this would quadruple (Z^2 dependence), even though the electron's mass energy is the same An electron in the Bohr model has a kinetic energy of 13.6 eV and a potential energy of -27.2 eV, but we must recall the Bohr model is not a physically correct depiction. -

If electrons had a trajectory, they would be accelerating, and would radiate. QM is why we have orbitals and not orbits, and the location is undetermined unless measured. The relativistic corrections are to the energy, not the speed. Most journal papers are careful about this; many pop-sci descriptions are not. It's a sloppiness of explaining things with classical descriptions that don't actually hold up when compared to the science. It's understandable when you're trying to reach a broader audience, but in this case it's watered down to the point where it's wrong. Yes, but I was trying to make the point (to the OP; you already know this) that in science we quantify things. And the situation being proposed has been looked at, and the only effect we see is the one we know about. It's small, and it leaves no room for some other conjecture. -
I doubt it. Quantum computing helps with factoring, so it helps when when you have a number that's the product of two large prime numbers https://en.wikipedia.org/wiki/One-time_pad#Quantum_and_post-quantum_cryptography an adversary with a quantum computer would still not be able to gain any more information about a message encrypted with a one time pad than an adversary with just a classical computer. Whether a book cipher counts, I'm not 100% sure, but it's not the kind of encryption the quantum systems are supposed to solve. Trivia: I once saw that someone had addressed a letter to my workplace with the proposed recipient "Beale cipher crew" I can neither confirm nor deny that such a crew existed

We do, in accordance with E=mc^2 IOW, in accordance with mainstream physics. But because c is so big, the mass change is small, and difficult to observe. But that's been done; an isotope of Fe in a Penning trap was observed to have two different frequencies, which means two masses - one for the excited state and one for the ground state. http://blogs.scienceforums.net/swansont/archives/278 In principle, any energy other than that associated with linear momentum of the center-of-mass will raise the mass of an object. Again, this is standard relativity, and not evidence in support of any new hypothesis (in fact, it's likely evidence against any new hypothesis, since we only see the increase that we expect.) QM doesn't treat electrons as moving; there is no classical trajectory one can assign to them. -
