I have a simple questions
I have a system in which the system will never reach -180 degrees for any frequency.
Does that make the gain margin infinite ?
If yes, does that mean that the system will always be stable for any gain ?
Thanks

You use the word "exist" and in any circuit that "exists", due to the speed of light being finite, there will always be a frequency where there is an inversion of signal aka 180 degrees phase shift.
No you don't - not in this universe.
