Why God Doesn't Exist
How a theory morphs into
a hypothesis

    It has long been tradition in the religion of Mathematical Physics that a theory becomes a fact after it is
    accepted by the majority. A ‘certified’ theory is simply one for which no one believes that there is yet a
    fatal flaw. Until someone does falsify it to the satisfaction of the many, presenters temporarily treat them
    as if they were established facts. A theorist assumes that the theory is true because most experts believe
    that there are no conclusive arguments to overthrow it. This gives a theorist confidence to convert such
    theory into a statement of the facts and build new theories upon it.

    “ Any physical theory is always provisional, in the sense that it is only a hypothesis:
      you can never prove it. No matter how many times the results of experiments agree
      with some theory, you can never be sure that the next time the result will not contradict
      the theory. On the other hand, you can disprove a theory by finding even a single
      observation that disagrees with the predictions of the theory.”  (p. 10) [1]

    What these conventions really reveal is the process by which a theory stealthily morphs into a statement
    of facts (i.e., assumptions, hypotheses). It explains why this metamorphosis utterly confuses the
    philosophers. What is occurring is that a theory in one presentation is taken so much for granted that it
    is effectively used as part of the hypothesis of another. Here are a couple of noteworthy examples:

    A theory is a particular explanation for a particular phenomenon. A theory may answer questions beginning
    with how (causal) or with why (reason, purpose). Once accepted by the majority, a theory doesn’t become
    knowledge. It can at best become a hypothesis that is used as a foundation to generate new theories.

    Keynes’s economic treatise, The General Theory of Employment, Interest
    and Money, [7] had the following structure:

    Presentation 1         (Keynes, 1936) [8]

    Hypothesis:     Aggregate demand
    Theory:             Aggregate demand explains variations in large-scale economic
                               activity (macroeconomics)

Contemporary theorists take Keynes’s macroeconomic theory for granted. They don’t
attempt to prove macroeconomic mechanisms any more:

    “ Keynes’ economic prescriptions are now so generally accepted… that many of
    us find it hard to recognize what the argument is all about. These days it is taken
    for granted that the government has a responsibility to stimulate the economy
    out of recession, at least to the extent of reducing interest rates, and modestly
    applying the brakes during over-exuberant expansion. It is accepted that two of
    the factors exacerbating economic downturns are the fearfulness of investors in
    the face of declining corporate earnings and the reluctance of consumers to put
    down money they suspect they may need later if they are laid off from their jobs.
    It was not always so.” [9]

Instead, they invoke Keynes’ macroeconomic model to formulate the statement of the
facts, and use this foundation to explain another theory, for example, microeconomic
effects:

    The Paradigm shift

    (The theory in Presentation 1 becomes a hypothesis in Presentation 2)

        Presentation 2

    Hypothesis: General, macro-level trends (from Keynes’s macroeconomic
    theory) [10]

    Theory: Macroeconomic factors can affect the micro-level behavior of individuals:

    “ Is the subjective nature of each individual’s personal valuations beyond the
    reach of our macroeconomic models?” [11]

    “ This paper is not concerned with energy efficiency at the microlevel, that is by
    the individual consumer or firm, but at the macro-level, that is at the aggregate or
    national level. Its question is ‘does the promotion of energy efficiency (at the micro-
    level) reduce energy consumption (at the macro-level)’? It presents arguments
    that the precise effect of energy efficiency decisions at the microeconomic level
    is impossible to quantify at the macroeconomic level.” [12]
In 1916, Schwarzschild theorized that a massive star would undergo total gravitational
collapse and convert into a black hole.
[2] The black hole was a theory for a great part
of the 20th Century and did not really become part of the mainstream religion of relativity
until after the 60s. At that point, relativists began to convince each other that a singularity
was the only mathematically viable end for a massive star. The mathematicians had
already accepted quantum magic and irrational relativity, so why not the black hole too?
Thus, the black hole entered the mainstream. Did this make Schwarzschild’s black hole
a fact? No. The theory morphed into a statement of the facts, into an assumption.
Contemporary theorists no longer explain nor justify to their colleagues what a black
hole is or how it is created. Today, the establishment takes the black hole for granted.
The modern ‘physicists’ assume (i.e., hypothesize) that black holes exist and use them
as a basis to persuade their colleagues of something else, for example, that a black hole
can create particles.
[3] Kuhn referred to this process of converting theories into
hypotheses as a paradigm shift.
