I will explain why I am asking this question. Let's say, there are mathematical truths and truths about our physical reality. But, there is no way we can establish the truth of any statement about our Physical Reality.
Consider a mathematical statement "There are infinitely many primes", I can give a formal proof to establish the truth of this statement.
Consider a statement about our Physical Reality "Sun Exists", I can give many Physical evidences that correspond to the Existence of sun, but still, there is no way I can establish the truth of the statement, like the Mathematical statement.
So, what is this distinction that sets apart Mathematical Truths from Physical truths? Or Is there anything such as Physical truths? Even if so, Mathematical Truths are "kind of" different from truths about the Physical Reality.
