Introduction
This thread is not against or pro God. It is a discussion on quantum theory and the challenges that pertain to it. I will discuss the questions on relation to God as we walk the talk.
It is my desire to put this subject across. There are a few atleast who want to know about quantum theory from the start . That is my attempt here . I may be inaccurate in places. Feel free to correct these ideas where you find inappropriate based on actual citations.
Let me start with a Story.
My two friends they visited a railway station standing on the platform. A train was passing by the station. The passengers in the train were amused as they observed the people in the platform moving in the backward direction from them. My first friend was amused by the passengers dissappearing from view- " Are these people floating away from me he wondered". Suddenly he found something strange. He looked around, the people he observed in the train were around him and stationary. Yet his other friend was outside moving away from him. He realized he was in the train. How did I come here?What happened to my friend. What is he thinking of me. - he thought.
This sounds like an age old story of relative motion there is a difference though. From a passive observer my friend became an active participant along with the rest of passengers. Yet he did not know this change coming through. How did he come into the train. Was he drugged and brought in? Was it that he unconsiously got into the train without realizing it. Was his mind playing tricks. What was the friend left behind in the station thinking? This story you see serves to explain more than relative motion.
I will come back to this story when I discuss more on quantum theory. Remember that I would be choosing to use it as an illustration on quantum theory.
Quantum theory was beginning to take shape even during the times of Max Planck. However the word Quantum Mechanics was coined by Neils Bohr. The word quantum is derived from the latin word quantum meaning how much.In physics it is defined as the smallest quantity of a physical property, such as energy,that a system can possess according to quantum theory.
Neils Bohr believed that atoms could exist only in certain states. An electron in an atom can move from one orbit to another causing a change in the state of the atom. This is accompanied by release of or absorption of energy. Thus each orbit gets associated with an Energy level. This many of us know since high school. We need to understand here that only certain orbits with certain distance from the center exist. In other words the energy states in an atom are only certain values. You cannot have an orbit at an arbitrary distance from the center of the atom. One could therefore say that energy for the atom is quantized. There were a few things in this model which was not right. This theory was later corrected to what we currently understand today as quantum mechanics. To understand the situation we need to travel back in time to Europe, to the city of Copenhagen. In this place assisting Bohr, was yet another person, who was to become famous on his own right- Heisenberg. This is what Heisenberg had to say
We must understand that this is not as absurd as it sounds. Can we see the orbits of an atom? Is there a microscope that can do that? Think about it!
Heisenberg developed what is well known today as matrix mechanics. It depended on the theory of observables.
In discussing this idea of observables I found it good to relate a conversation between Einstein and Heisenberg.
From Heisenberg, Physics and Beyond, Arnold J. Pomerans, trans. (New York: Harper, 1971), p. 63. (Ref 2)
We see in this conversation the difference in approach. What Heisenberg is doing is developing his theory from observable quantities. If we follow the opposite approach , in order to explain a phenomena we can postulate the existence of a certain particle. But does that particle exist. This has to be experimented by putting the experiment to test. One cannot say this will lead to wrong conclusions. It is just a difference in approach.
However if we follow Heisenberg's approach to explain matters where we suspect god's powers, we must avoid discussion on God. Because God is not an observable. The alternate approach is to believe that God exists and then put the theory to test. Both are valid approaches in my opinion. What matters is if the theory when put to test explain away all contradictions , all inconsistencies and give only one possible answer. It seems to me like some people in this forum like Sravna are fascinated by this latter approach. Nothing wrong per say as long as a theory puts to rest any speculation.
Anyway we must bear in mind the crucial difference in development of theories before defining things like observer, event etc. These definitions could vary according to the theory.
The below quote should explain Heisenberg's approach.
Ref 3
We see here a problem already beginning which will prove that newer theories have to emerge. What is that? Heisenberg is constructing his theory based on observable properties of matter like Amplitude, energy etc. Observables are related to human experience. Let us please note this down. This means that what cannot be observed by humans at a point of time, is going to create a problem because our theory cannot be complete. This is not only my view, it will be later taken up by Bohm.Infact coming to think of it,Vedantins will have a problem with this. How can we assume that Jivatma have a complete cognizance and powers of observation. What happened to the invisible worlds , invisible layers of bodies etc etc. All these will be ignored as we proceed on the lines of Heisenberg until the Jivatma becomes a Paramatma. Which means that the correct theory of Universe will never emerge in front of the Jivatma if he follows the line of Heisenberg.

( Ref 1 )All of my meagre efforts go toward killing off and suitably replacing the concept of the orbital path which one cannot observe.

Heisenberg: "We cannot observe electron orbits inside the atom...Now, since a good theory must be based on directly observable magnitudes, I thought it more fitting to restrict myself to these, treating them, as it were, as representatives of the electron orbits."
"But you don't seriously believe," Einstein protested, "that none but observable magnitudes must go into a physical theory?"
"Isn't that precisely what you have done with relativity?" I asked in some surprise...
"Possibly I did use this kind of reasoning," Einstein admitted, "but it is nonsense all the same....In reality the very opposite happens. It is the theory which decides what we can observe."

If we follow the opposite approach , in order to explain a phenomena we can postulate the existence of a certain particle. But does that particle exist.

Ref 3
As a first step, Heisenberg had to identify the relevant observables. In atomic
physics, observational data related to atomic transitions arising from interactions
of the atoms with light quanta. Heisenberg therefore argued that these transitionrelated
quantities are the basic relevant objects. A detailed investigation on
these lines led him to propose the first coherent mathematical structure for the
quantum theory of atoms, in 1925. Together with Max Born and Pascual Jordan,
who recognized that these quantities obeyed rules prescribed by matrix algebra,
Heisenberg developed the essentials of matrix mechanics later that year.
We see here a problem already beginning which will prove that newer theories have to emerge. What is that? Heisenberg is constructing his theory based on observable properties of matter like Amplitude, energy etc. Observables are related to human experience. Let us please note this down.
