Mathematics is quantitative extension of logic. It can move beyond logic only in exact quantitative terms. The basic realities are discovered through observations. Secondary realities are discovered through logic. Quantitative realities are derived from basic and secondary realities by using mathematics.
Unfortunately Modern Physics is built on assumption that mathematics itself is capable to discover unknown realities of Physics. We often read in science literature that physical fact ‘x’ was already ‘predicted’ by equations ‘M’ so physical fact ‘x’ is considered as a necessary consequence of equations ‘M’ and interpreted only within the context of same equations ‘M’.
In the Big Bang Theory, there is a deceptive claim that in year 1927, Georges Lemaître had ‘mathematically predicted’ physical fact of linear relationship of redshifts and distance whereas that mathematical prediction came true in year 1929 when Edwin Hubble experimentally found the same linear relationship. Only because the said relationship was already mathematically ‘predicted’, mainstream Physics did not feel the need to see whether that kind of relationship could be considered as physical proof of expansion or not. Only because already available mathematics was talking about ‘expansion’ so the newly found linear relationship was simply interpreted in terms of ‘expansion’.
Likewise, CMBR type radiation were already ‘mathematically’ predicted. When apparently same type of radiation were experimentally found, then again mainstream Physics felt no need to find the actual reason of those radiations and they were simply interpreted within the context of already available mathematics.
Right method should be Observation>>>Logical Interpretation of observed reality by evaluating all the possible explanations>>>Quantified Model using Mathematics. (This method implies that mathematics itself does not find unknown realities)
The actual prevailing method of Modern Physics is like Mathematics>>>apparent resemblance of later on found physical facts with already available mathematics>>>Hue and Cry that ‘mathematical prediction’ has come true>>>adaptation of already available mathematics (with few modifications) as final interpretation of newly found physical facts. (This method implies that only way to find unknown is the way of mathematics)
It is often stated that Einstein had found hard physical realities through the way of mathematics. Bending of light ray was experimentally confirmed during a Solar Eclipse etc. The thing to be noted in this case is that after reaching at ‘Equivalence Principle’ with the support of Eötvös experiment (Observed physical fact), First of all Einstein had logically evaluated the stuff. If acceleration due to gravity was independent of mass (a logical interpretation of physical experiment) then light also must accelerate under gravity (logic). But according to his own theory, speed of light could not be affected (logic). If speed of light could not be affected then there were two (logical) options; (i) Wavelength of light could be affected (gravitational redshifting) or (ii) light could change direction (i.e. other logical form of acceleration).
Thus logic took him to the idea of bending of light. Next stage was quantification i.e. ‘how much bending’. From this point onward the role of mathematics entered to the scene.
Therefore mathematics had not found unknown reality in this case. More specifically, if Solar Eclipse experiment had really confirmed anything then it was that (logical result out of observation) acceleration due to gravity was independent of mass.
However if we try to look at further details, then keeping in view the personality of Arthur Eddington who actually performed 1919 Solar Eclipse Experiment, the whole confirmation of General Relativity on the basis of this experiment sounds notorious and unreliable.
Arthur Eddington, within mainstream interpretation, had confirmed that mathematics really found unknown realities. Eddington again played a crucial role in 1931 when it was almost established that Georges Lemaître had already ‘mathematically predicted’ Hubble’s law in year 1927. However, later on, the same Arthur Eddington, in the case of Subrahmanyan Chandrasekhar, would refuse that mathematics can find unknown realities of Physics.
But since Chandrasekhar’s point of view was succeeded at the end so mainstream Physics ignored the confession of Arthur Eddington that Mathematics itself cannot find realities of Physics.
Role of mathematics is also important to be clearly explained and limits be identified within the domain of Philosophy. Below I am quoting a relevant portion of my upcoming book “Descriptive Knowledge, Mind and Reality; a case of Epistemological Realism”:
