What’s Wrong with String Theory?

Currently, the foundational physical theories are Einstein’s general theory of relativity, which describes gravity and has been confirmed by many observations and experiments, and quantum mechanics, which represents the behavior of particles and fundamental interactions such as weak, strong, and electromagnetic forces. However, these two theories are incompatible, and in attempts to resolve their contradictions, many other theories have emerged, including string theory. In 1970, some scientists proposed the idea that the interaction between pions (a type of particle) during collisions arises because the pions are connected by an “infinitely thin thread that vibrates” — a string. Subsequently, models appeared in which elementary particles are in the form of strings that vibrate at specific frequencies. <a href="https://medium.com/@deep.space/whats-wrong-with-string-theory-94ae26a99007">Click Here</a>
