The premise here is pretty weird. There is a whole branch called philosophy of science. You can&#x27;t just say something that is wrong or untestable is by default is philosophy.<p>Also, physicist have proposed some experiments and observation such as regarding the cosmic microwave background radiation. There is a book called &quot;The Trouble with Physics&quot; and many articles on the subject. There is something to be said about many claims in theoretical physics and the lack of testability but I think this is not rigorous enough and too loose with the labeling.
