This accusation is made by one physicist in the streaming video links provided by Integral [Thanks Integral! I had missed these shows when they aired and I was POed!]. I have heard or read similar statements elsewhere. As I understand the state of the theory, whatever its latest evolution is properly called [M Theory still?, or is it N Theory now?], no one has conceived of any experiment that could actually be done to test this theory. If none are known to be possible, then how long can this considered to be a subject of physics? In this sense, Physics without a testable hypothesis is Philosophy.
I have a vague understanding of ST, and I appreciate to some extent why the theory is so attractive, but I don't understand the acceptance as a viable theory if in fact it may be "forever safe". Based on what I have heard and read, acceptance of this as science strikes me as a very treacherous position for physicists to take.
Enlightenment or comments? Again, I don't claim to be an expert here; this is only what I’ve heard and read. My read on this so far is that until a testable hypothesis is at least suggested, ST is philosophy.
