There is no such thing as an untestable theory of science. Science is not a profession.Thanks for tacitly admitting that untestable scientific ideas and inferences have an important place in the scientific profession.
No, they are not simply just a random 'place holders'.
They are logical inferences and deductions from existing scientific data and principles.
Science is not data. Science is not religion.
Quantum mechanics has no 'meaning'. Religion is not science.The Many Worlds interpretation of quantum mechanics makes very specific logical inferences based on the mathematics of quantum mechanics. It's basically a philosophical interpretation of the ultimate meaning of quantum mechanics.
String theory is not a theory of science.Superstring theory is an elegant mathematical idea that makes very specific mathematical deductions about the nature of ultimate physical reality. But it is not testable, and there is nothing on the horizon that will ever make it feasibly and directly testable.
