So you are twins
Just looked up the definition:
SpoilerSo, if they are two of five, they are not called "twins"?

Does it mean day / month / year?

A woman goes to a company to fill out a job application. As the secretary looks it over, she says, oh we had someone apply yesterday with the same last name, same parents, and same date of birth.
That's my sister, said the woman.
So you are twins, said the secretary.
No, we are not, said the woman.
Explain.

I think the image of Nikola Tesla on the first video should be considered a big red flag as far as pseudoscience is concerned.
This is my experience as well.

Similar effect allows bacteria to withstand much higher osmotic pressures than eukaryotic cells. In this case, it is the line-square rather than the square-cube law. When you decrease the size by a factor, the ability of a membrane to withstand tear decreases by that factor while the tearing force decreases by the factor squared. Thus, a bacterium that is 100 times smaller than a regular cell can withstand 100 times higher osmotic pressure.

Can we bottle (or just create) spacetime curvature and thereby create (or annihilate) mass?
That might be a causal relationship.
Spacetime curvature is associated with radiation. The latter does not have mass.

the concept of zero point energy implies there is a sort of ineradicable residual motion in the ground states of bound systems
Is it a motion?

ok from my understanding, it is the belief that everything is made of vibrating energy including thoughts and people and like energy attracts like energy so positive thoughts attract positive experiences and negative thoughts attract negative experiences.
None of this *** has anything to do with quantum theory or the science of physics.

Indeed. Sorry.
Well, then the question about the field changes to: what are the fields and how they were created?
What they are is described by specific QFT theories. Generally, field is an entity that pervades space and time and is defined by its properties such as spin.
"How they were created" goes back to the dawn of the universe.

the electromagnetic field was successfully "discarded"
It was not. It is rather the other way around. Photons are quantum excitations of EM field. The QED and other QFT theories describe interactions of fields. (QFT = Quantum Field Theory.)

I would ask.
Does the QFT provide a sufficient answer?
1 hour ago, Moontanman said:how a charge creates an electrical field
It does not. Not in QED, the best current theory.

But the questions I brought up, are specific to see if making an object to behave differently under a condition. (e.g. trying to apply a concept or approach that is different from ordinary or convenient approach).
How your questions are different from ordinary or conventional approach to behavior of objects under gravity?

Make it short. Embed figures. Use LaTeX for formulas.

I have some questions that I'm curious about before moving on:
Q: If making objects with less dense mass property alongside with perhaps a change in direction, would these be able to lift or float up (e.g. artificial anti-gravity)?
Q: If making objects with greater dense mass property alongside with a change or more concentrated direction, would these able to ground astronauts on a floor in spacecraft or space station (e.g. artificial gravity)?
The law of gravity is known. Try to answer your questions by applying it.

more than one infinite universe could co-exist in a natural way
As I have mentioned, there are many ways. One of them is that the multiverse's space is not necessarily three dimensional.
17 minutes ago, Airbrush said:How can a finite universe not have a center or edges?
If its geometry is not Euclidean, for example.

Why should this be true? What makes the visible universe spherical is that the limits on the speed of light are the same in every direction, AFAIK there is no spherical symmetry to the mass in the visible universe, what would make it symmetrical outside of it?
On the scale of several hundred megaparsec and more the visible universe is homogeneous and isotropic. It means that on that scale it is the same in all directions.

once we figure out a reliable way of measuring gravitational effects from bodies outside our visible universe on bodies inside our visible universe
As the bodies outside our visible universe make pretty much spherically symmetric shell, their gravitational effect inside the shell is identically zero.

it was a language trick (and I learned something new), because in Russian, they are all близнецы regardless of number.
