ehcks, firstly gravity isn't simply a downwards or even an inwards one but I'll explain this later.
You seem to have a lot of things to explain later.
But your assertion and that of similar ones by others: "electromagnetism repels you from the ground, thereby canceling the continuing force of gravity that would otherwise pull you into the core of the earth" is nonsense.
Newton's Laws of Motion, Ken. F=ma. ehks is 100% correct and you are 100% wrong.
Gravity is NOT all powerful everywhere.
Irrelevant.
It has what is referred to as a "gravitational constant."
Irrelevant to the question and irrelevant to the previous point.
Physicist have done experiments to measure it and it has a value (look it up).
Irrelevant.
This constant is a multiplier of the masses in question.
Irrelevant.
See even Newton's simpler equation vs Einstein's.
Irrelevant.
To make a long story short, the mass/energy/density of the Earth isn't high enough to "pull you into the core of the earth" or as is implicated to form a black hole.
We know that, Ken.
But
why isn't the mass of the Earth enough to cause it to collapse into a black hole? What is the force that is counterbalancing gravity?
Secondly, the idea that in neutrally charged objects like humans and the ground there is an EM repulsion that repels us from the ground, thereby canceling the force of gravity, is nonsense.
You are, of course, making a terrible error here.
Let's take two objects, negatively charged at one end and positively charged at the other. The net charge on each one is zero.
If we push the two negatively charged ends together, what is the resulting force (again, considering only electromagnetism)?
1. Attraction
2. Repulsion
3. Zero
Neutral particles don't repel each other.
No, neutral
particles don't. This is, of course, irrelevant.
There isn't any such thing as this sort of so-called "quantum mechanical EM repulsion."
100% wrong.
We understand the EM force via quantum mechanic's Standard Model.
No, we understand it through classical and quantum electrodynamics.
The people who think neutral particles/objects repel have no idea what they are up against.
We know exactly what we're up against, Ken. Answer my question above, and you will too.
It's not me! It's the Standard Model. It is incomplete but is one of the most successfully tested models in the history of physics!
As I said earlier, you seem to have arrived at the Standard Model without passing through Kepler, Galileo, or Newton. What you are proposing is completely impossible in every imaginable way, and scientists have known this for centuries.
Further, you can't use vector mechanics to solve problems of a quantum mechanical nature.
Ultimately, everything is of a quantum mechanical nature, and yet we use vector mechanics just fine.
Also, PixyMisa has clearly stated this EM repulsion (of the form in discussion) is "universally" accepted by physicists.
Actually, everyone in the thread has told you that. We've even had a working physicist (Sol Invictus) come in and tell you the same thing.
He hasn't, nor has anyone cited even one clear specific reference.
We have, you have simply been unable to understand them. That's why I'm asking you very, very simple questions to try to guide you forwards.
All I've seen are general articles on EM or some other subject, including the recent bizarre ones about vector mechanics!
Which you apparently haven't read or understood.
How can it be "universally" accepted?
Because it's true. It's the foundation of all of engineering and materials science. It's taught in every decent high school on the planet.
I hope this answers your question.
It explains that you don't understand Newtonian Mechanics, yes.
