Bilge writesJohn Kennaugh:John, ask Bilgey the following questions:
How can the light emitted by a remote star immediately find itself travelling at c wrt every other object in the universe?
Does it somehow possess an infinite number of speeds?
Standard answer:
'Relativity is a principle theory and as such does not attempt to answer those sorts of questions.'
As far as I can see from Einstein's own definition of a 'principle theory'
"The elements which form their bases and starting-point are not hypothetically constructed but empirically discovered ones, general characteristics of natural processes, principles that give rise to mathematically formulated criteria which these separate processes or the theoretical representations of them have to satisfy. They employ the analytic, not the synthetic, method." AE
It makes relativity a mathematical model. No! says Bilgey it is a physical theory. He is yet to explain how Einstein's own definition differs significantly from that of a mathematical model.
"The advantages of the constructive theory are completeness, adaptability, and clearness, those of the principle theory are logical perfection and security of the foundations." AE
Implying that the disadvantages of a principle theory are that it lacks the advantages of a constructive theory i.e. instead of completeness, adaptability, and clearness a principle theory is incomplete, inflexible, and vague. I am also at a loss as to the 'security of the foundations' of relativity. It is based on a belief in source independence which comes from belief in ether theory. Far from being 'secure' no one these days believes in what it is founded on.
