Philosopher Karl Popper defines what a theory is and what is just babbe-maise (he is not using the latter term): could you suggest a potential fact that will overturn the theory? for example, a theory that vaccine is effective can be tested by a carefully constructed double-blinded test.
In case of phils writing above, he seems to reject any proposed proof or any widely proposed remedy as a conspiracy and, in turn, accepts anything that is not accepted widely as vadai remedy. I can’t come up with any potential piece of information that phil will not reject on these grounds.
