String theory is currently a mathematical model without experimental evidence to support or refute it, making it difficult to classify as a "real theory." It encompasses multiple versions that vary in the number of dimensions required. The discussion highlights the ongoing work needed in both mathematical and experimental domains to validate or invalidate string theory as a potential unifying framework for general relativity (GR) and quantum mechanics (QM).
PREREQUISITESThe discussion is beneficial for theoretical physicists, students of physics, and anyone interested in the intersection of general relativity and quantum mechanics.
It's hard to guess what you could mean by "a real theory". I would be joking and say, no, it's a complex theory. At the moment it is only a mainly mathematical model for which we don't have any experimental evidence, neither to favor it, nor to fault it. So it cannot be answered yet, whether string theory is the final answer to merge GR and QM. By the way, strictly speaking it isn't even one theory but many. String theory is a common headline for various versions. They differ for example in the number of dimensions they need.

My question: is the strings theory a REAL theory ... is it really the final answer to the relationship between relativity and quantum mechanics! ? [emoji54]
