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. If you're interested in it, you could read the Wikipedia entry on it https://en.wikipedia.org/wiki/String_theoryMary curie said:Hello everybody! I hope you are having a great day !
My question: is the strings theory a REAL theory ... is it really the final answer to the relationship between relativity and quantum mechanics! ? [emoji54]
No, string theory is not yet a proven scientific theory. It is still a theoretical framework that has not been experimentally confirmed.
The main idea behind string theory is that matter is made up of one-dimensional strings rather than point-like particles, and that these strings vibrate at different frequencies to create the different particles and forces in the universe.
Currently, there is no experimental or observational evidence to support string theory. However, there are ongoing efforts to test certain predictions of string theory through high-energy particle accelerators and other experiments.
String theory attempts to unify the four fundamental forces of nature (gravity, electromagnetism, strong nuclear force, and weak nuclear force) and reconcile them with the principles of quantum mechanics. If successful, it would provide a single framework to explain all physical phenomena in the universe.
Yes, there are several criticisms and challenges to string theory. One major criticism is that it currently lacks experimental evidence and therefore cannot be considered a scientific theory. Other challenges include the existence of multiple versions of string theory, the lack of a unique solution, and the difficulty in making testable predictions.
