The QM Model is incorrect and the Standard Model is a poor excuse for a job.
Here is the correct model 3d simulation of an atom at my Website. Here is a
Hydrogen atom. It is made of intelligent logical Helix Spiral Field interacting
structures, internally and externally.
The world has rejected me and the Smart Model because they are to far behind
and primitive in science. The Smart Model is like an intelligently designed
computer. It has internal and external structures. The Standard Model is like
blowing up or colliding computers to see what flies out of it. If a IC chip
flies out after the collision then it is called a Quark or another particle.
The Smart Model is the only atomic and sub-atomic model with structure inside
and out. It is original and helped in the creation of this universe. Without
this model this universe and others don't exist, only choas and stupidity QM
Bull Crap exists. The QM model has contributed to the chaotic state of this
universe. The Smart Model tries to make corrections as much as it can. At least
the world after this one has a logical eternal structure without death. It is
worlds ( humans) with free will choice that help in making their own world. I
have already visited some other worlds, and just recently I visited one that
finally has a logical time flow of space and time. it can be observed in a
dream state or astral projections.

I am one of the Co-Creators of this universe. I helped establish the
universal fields that establish Free Will Choice Worlds. Even in the Holy Bible
and other religious books like the Quran etc..., show that Free Will Choice is
fundamental to a life existing being. Many have misunderstood what this has
meant in the fields, anti-fields and neutral zones fields of atomic and
universal structures.
I am here to help enlighten people to the TRUTH. The Truth is that YOU can
also have your own world without limits ( you can do anything in your world,
WITH OR WHILE RESPECTING the free worlds of other beings. This particular world
( EARTH) has problems because there is lack of respect for the other
individual free worlds of each being and species. A corruption state occurs
when a person is invaded and things are taken from his/her world ( or home)
here on Earth. In the next world which was also Co-Created with the Smart
Model, YOU CAN FINALLY BE FREE and live and prosper. Some call the place
paradise. It is YOUR paradise. You can make your world Heaven or Hell.
Universes will remain parallel so that each individual universe with not
collide and disturb the others. This is the Truth. Many Prophets have talked
about the Truth. I show the Creation that THEY speak about. I am a Co-Creator.
Where is God? Well, He isn't some BIG ruling dictator that everyone expects. He
is a simple person like you and me that sets an example for others as a servant
so that space, energy matter and time isn't invaded by Him, so others can have
they own free space and time and world with other beings. So you can be free in
your own world.
There is no Judgement Day, only a CHOICE Day. It doesn't matter what you
have done in the past because many problems were put on you against your will
to start with before you even had a choice. THEN you reacted in a counter
inappropriate way. ALL sins ARE forgiven because there IS NO SIN. Why? Because
most of the time people ask, why do people suffer and die? Well since they
don't understand or know why, they can't be guilty. So they have no sin. No
blood sacrifices are needed. Only enlightenment to the Truth is needed. This
Truth can be observed by you when you search for it.
