State of "matter" of a singularity
It's not clear that gravitational singularities exist, and we don't have the physics to describe such things. "fundamental form of energy" doesn't make sense.

Pfizer Vaccine: Long Term Side Effects
You're responding to the part which was not in question and to which I was not objecting, and ignoring the part I was. You were lumping all of the vaccines together under one umbrella and ignoring (possibly important) distinctions between them. Your OP was about Pfizer and lipid nanoparticles, and all of the sudden you're talking about blood clots, which are not associated with the Pfizer vaccine.

What does the ‘infinite monkey theorem’ suggest about the anthropic principle?
An excellent point, which serves to show that the monkey argument carries a hidden, unsupported, and probably very bad assumption that life could only arise through one particular path.

Pfizer Vaccine: Long Term Side Effects
This would be your opportunity to provide a link to support your claim. thrombocytopenia is a rare result in 2 of the vaccines https://www.uptodate.com/contents/covid-19-vaccine-induced-immune-thrombotic-thrombocytopenia-vitt VITT has not been reported after mRNA-based COVID-19 vaccines such as the BNT162b2 (Pfizer-BioNTech) or the mRNA-1273 (Moderna) vaccines despite administration and safety data collection from hundreds of millions of recipients. At least one of the available vaccines, (Oxford- AstraZeneca) is not an mRNA vaccine https://www.nytimes.com/interactive/2020/health/oxford-astrazeneca-covid-19-vaccine.html The Oxford-AstraZeneca vaccine is based on the virus’s genetic instructions for building the spike protein. But unlike the Pfizer-BioNTech and Moderna vaccines, which store the instructions in single-stranded RNA, the Oxford vaccine uses double-stranded DNA.

Are gender differences in personality traits mostly due to culture or biological differences? (Split from “choose gender option”)
Which is not evidence that this is of biological origin. Repetition of claims is not evidence for them. Again, no evidence being presented, even if some elements of this are true. And so on...

Why the electron probability density is maximum at the nucleus? (split from Electron Probability distribution)
A behavior you have admitted to not studying and having no expertise in understanding. Analogies are limited in usefulness. Analogies of quantum systems are typically more limited. Again, it’s preferable to actually discuss QM.

Why the electron probability density is maximum at the nucleus? (split from Electron Probability distribution)
Meanwhile you are still not a quantum particle. The physics of your behavior is quite adequately described by classical physics, and this is still not relevant to the topic of the thread.
-
Why the electron probability density is maximum at the nucleus? (split from Electron Probability distribution)
And? You need to include the part where you explain how this has relevance Not clear what your position is. So this, too, is irrelevant to the topic. That’s not what I said, so I don’t know what prompts this question. Reading comprehension issues? Rule 2.5 Stay on topic. Posts should be relevant to the discussion at hand. This means that you shouldn't use scientific threads to advertise your own personal theory, or post only to incite a hostile argument.

Why the electron probability density is maximum at the nucleus? (split from Electron Probability distribution)
I don’t see how that’s relevant to the topic. You can look at the graph (or equation) of the probability density for various n levels and compare. If you have questions about it you should ask. You perhaps overestimate how much I keep track of others’ backgrounds. If you want to discuss QM, and especially if you assert that it works a certain way, I assume a certain level of familiarity. If that’s lacking, then this is a waste of time; you can’t build a proper model or assess criticism of your idea. The topic here is the electron’s wave function and probability density. Tying in to other speculative ideas is against the rules.

Why the electron probability density is maximum at the nucleus? (split from Electron Probability distribution)
Not really. You are not a quantum particle, and location isn’t a property that has a quantum number. Can we deal with actual QM and not analogies? That removes much of the ambiguity. Answered. It’s because of the math, both “this is what the math is” and “because you’re using spherical coordinates”; the volume element depends on the radius. The probability density isn’t the quantity with physical meaning, so there isn’t a physical justification I can give. Answers get merged. And if I edit immediately, I usually don’t annotate it.

Why the electron probability density is maximum at the nucleus? (split from Electron Probability distribution)
And yet what you wrote is in agreement with what I wrote regarding the PEP No, there is nobody identical to you. In hydrogenoid atoms, the energy of an orbital is only a function of its main quantum number, n, which means that all the orbitals of the same shell will have the same energy. In a single-electron atom, an electron in a 2s orbital will have exactly the same energy as an electron in a 2p orbital, because they only interact with the nucleus through a Coulombic interaction Citation? You quote something, you need to provide a link. There’s probably something that says this is what’s predicted by the Schrödinger equation. This turns out to not be true, once you delve a little deeper into quantum physics. It’s called the Lamb shift. https://en.wikipedia.org/wiki/Lamb_shift This also ignores the hyperfine splitting, where the spin of the electron matters in determining the energy.

Why the electron probability density is maximum at the nucleus? (split from Electron Probability distribution)
“all due respect” usually indicates disagreement. One of the components of the PEP is that you have identical particles, as I indicated. If they are unique they aren’t identical. If it’s on “another shell” then there is some difference in its state (whatever you mean by A or 1; we do have actual physics terminology we could use) e.g. an electron in n=2 and the s state, can be spin up, and also have an electron in n=3, s state that is spin up. Such as you’d find in Ar. “on the left” really has no meaning in this context.
-
Why the electron probability density is maximum at the nucleus? (split from Electron Probability distribution)
If electrons were unique they wouldn’t end up in all these different states. It’s because they are identical that they need to be in different n, l or m states to satisfy the Pauli exclusion principle

Electron Probability distribution
What I said conveys pretty much the same information about hyperfine structure as the quote you provided, so yes. Why do you ask?
-
Electron Probability distribution
Some quantum particles, like electrons and protons, behave like little magnets, owing to having a charge and intrinsic angular momentum (spin). So a “spin up” electron will have a different energy than “spin down” in the presence of a magnetic field, which is provided by the nucleus. This energy splitting is the hyperfine splitting.

Electron Probability distribution
Of course density has a physical meaning, since you would typically have a volume of the material. The question here was the probability at the origin as well as nearby. The volume element depends on the surface area of the shell, so it’s smaller close to the origin, and zero at the origin, and this artifact of the math has to be included when discussing the significance of the wave function’s value. The nucleus has a physical size, so sure. The electron interacts electromagnetically and the fact the the electron can be found there accounts for the large hyperfine splitting of the s state as opposed to the p states, where the wave function has a node, and so doesn’t have nearly as strong an interaction. In alkali atoms the hyperfine splitting of the ground state is hundreds of MHz to >1 GHz, while the excited p-state is significantly smaller

But if it’s zero, are you considering a volume? How much mass do you have in zero volume, regardless of the density?
