God does not arbitrarily manipulate the laws of physics and perform miracles.

Defining God. There are three commonly held views on God that can be broken down by category. In the first view God can and does interfere with the universe, arbitrarily manipulating the laws of physics and performing miracles. In the second view, God is part of the universe and works to the laws of physic- we may have observed God already but have a different name for it (e.g. nature). In the third view, God does not interfere with the laws of physics but may have spun things into motion. In the first view, God would have some useful applications, however his decisions would be completely arbitrary- thus we could only speculate his reasoning. In the second and third view the natural processes of the universe would work to the same, and God needs not to be a part of a model of the universe. Premises. Our Current views on the motion of bodies date back to Galileo and Newton. Previously, views on the motion of bodies dated back to Aristotle. Aristotle stated that the natural state of a body was at rest, and that it only moved if driven by force. This followed that a heavy body should fall at a higher velocity than a lighter one, because it would have a greater pull to the earth. Furthermore, he proposed the laws of the universe could be worked out by thought, and observation was not necessary. As a result, those who accepted the Aristotelian tradition never bothered to see whether bodies of different weights did fall at different rates of speed. In fact nobody had tested his predictions until Galileo Galilei came along. Galileo demonstrated this belief to be inaccurate with an experiment. To explain, he rolled balls of different weights down a smooth slope, and found they landed at the same time at the same speed. In this experiment, Galileo found, that a body will increase it's velocity per distance fallen: X=(a*t")/2. These measurements were used by Newton as a basis in his laws of motion. In 1687, Newton made a publication, "Principia Mathematica" in which he stated that a body not acted on by any force, moves in the same direction at the same velocity. However, when acted on by a force, a body will change it's speed proportional to the force. In addition, he discovered that every body attracts every other body with a force that is proportional to the mass of each body. Therefore, it was governed by a few concepts, the mass of the objects and their distance apart. An example would be provided by a car: the greater the engine power, the greater the acceleration, but the heavier the car, the smaller the acceleration for the same engine. On the other hand, a lead weight would fall faster than a feather, but only because it is slowed down by air resistance: F grav-F air/m2=a. Concurrently, David R Scott demonstrated that a feather and a lead weight does fall at the same rate on the moon, where there is no air resistance. Therefore, a heavier body will have twice the force of gravity pulling: F grav=(G*m1*m2)/d", but will also have twice the mass. According to Newton's second law, these two effects will cancel each other, so the acceleration will be the same in all cases: F grav/m2=(G*m1)/d"=a. Observation did not agree with the predictions of Aristotle's views, therefore they had to be abandoned, following the scientific method. "It followed from the special theory of relativity that mass and energy are both but different manifestations of the same thing -- a somewhat unfamiliar conception for the average mind. Furthermore, the equation E is equal to m c-squared, in which energy is put equal to mass, multiplied by the square of the velocity of light, showed that very small amounts of mass may be converted into a very large amount of energy and vice versa. The mass and energy were in fact equivalent, according to the formula mentioned above. This was demonstrated by Cockcroft and Walton in 1932, experimentally."- Albert Einstein Before 1915, space and time were thought of as an arena in which events occurred, and remained unaffected by what occurs in it. However, Albert Einstein developed the special theory in which he stated that E=mc^2 or in other words the energy of an object is equal to the mass of an object times the speed of light square. If we add kinetic energy in the equation then it would follow that E=mv^2/2+mc^2, in which the energy of an object is equal to the momentum and velocity of an object and it's mass times the speed of light square. To explain, the velocity of an object is added to it's mass, and it should therefore follow, (assuming Newton's second law of motion) that the velocity of an object should increase it's force of gravity. "We are to admit no more causes of natural things than such as are both true and sufficient to explain their appearances." -Sir Issac Newton. Albert Einstein's special theory of general relativity suggested that spacetime is not flat, as previously assumed: it is curved, or "warped", by the distribution of mass and energy within it. In addition, gravity can be thought of as a hole in a body of water that stretches out forever, this hole would cause water to drain away affecting anything that falls within its distortion. In fact Einsteins equations had shown that space and time would be affected by the mass of bodies, and in turn, this would affect bodies in motion. Conclusion. "We can imagine that this complicated array of moving things which constitutes "the world" is something like a great chess game being played by the gods, and we are observers of the game. We do not know what the rules of the game are; all we are allowed to do is to watch the playing. Of course, if we watch long enough, we may eventually catch on to a few of the rules. The rules of the game are what we mean by fundamental physics..." -Richard Feynman. Imagine we could figure out the rules of the game, then play it backwards to find an initial state. However, this would not be possible if God was to arbitrarily manipulate these rules. To explain why, the universe would no longer work to the same laws. Therefore, our methods become unreliable. As a matter of fact, we not only assume the laws of physics remain constant, we absolutely depend on it. In a universe where the laws of physics remain constant, we can make predictions for future observation. If however, observation does not agree with the predictions made, then we have made a mistake. Science has established that God does not interfere with the laws of physics. Therefore, if a god actually exist he must be one of the remaining options available. If God is part of the universe and works to the laws of physics, we may have observed it. However, if this is the case then it's applications are not what Christianity claims it to be. Furthermore, if it God does not interfere, then (assuming Ockham's Razor) it should be left out of our models. Einstein's equations predicted that the universe had a beginning, and possibly an end, however we can only imagine what happened before the beginning of space and time, since General Relativity breaks down at a singularity. Correspondingly, if, as is the case, we know only what has happened since the big bang, we cannot determine what happened beforehand. As far as we are concerned, events before the big bang can have no consequences, so they should not form part of a scientific model of the universe. We should therefore cut them out of the model and say that time had a beginning at the moment of the big bang.
