God's Role in the Universe

Let me begin by saying that no one alive today can offer a complete proof as to whether or not God exists.  I was once at a talk where a philosophy professor proved the existence of a higher power.  Of course, his proof was based on a number of assumptions.
 
Who is God, and what role does He play in this Universe?  It is a philosophical question, and one well worth pondering.  As with most other thought-provoking questions to which there are no clear answers, the answer most parents would provide for their children is based on faith.  Many parents today will give an equally truthful response: “I don’t know.”
 
Still, man’s ability to observe the Universe, and make deductions based on what he finds, places him in a unique position.  Above all else, it is this unique skill combined with our insatiable curiosity that sets us apart from other animals.  Well, that, and we use rolls of soft tissue to clean our butts when we poop.

We Must Always Question Science

I am currently taking my Physics students through a quick synopsis of modern physics.  I have to catch myself on occasion from stating any relatively recent science developments as though they are factual.  The stories behind modern scientific discoveries are factual, but we must not be too quick to dub any finding a scientific law.

What in the scientific realm can we say we are completely certain of?  A scientific law is a rule that, in the eyes of the scientific community, has not yet been broken.  In science, we begin with a hypothesis or an observation, and devise an experiment that will test it.  Eventually, a theory becomes a law if it appears to stand the test of time.  It is easy to disprove a law; it just takes one example.  It is nearly impossible to prove a law to be true.  Mathematics is a relatively pure and exact discipline, and is borrowed by the science community on a regular basis.  Science is not a pure discipline in the sense that there is always human error associated with it.  By error, I do not mean calculation error, although there are plenty of those too. 

Fundamental scientific errors are made when the experiments are devised as a means of proving something.  This process is very difficult, as it requires a particular setup, and, inevitably, certain assumptions must be made.  Essentially, all experiments require that the scope of what is being tested be narrowed.  Although tempting, it is dangerous to expand the experiment’s results as applicable to other test setups.  A scientist’s greatest desire is to generalize a concept, but it is a leap that must be based on further experimentation, not a hunch.
