Is there a Fundamental physical property or constant which when tweaked, does not affect the universe much?
Sorry if I am not very discrete with the definition of "fundamental properties or constants", but I always see things like, if "this constant" or "that value" or "this property" were to be changed even slightly the universe would collapse, or would not exist, or something would explode.
I wanted to know, that is there something fundamental which when changed only a little bit, does not affect the universe to a great extent. #science
