AUDI R6 Posted July 18, 2019 Posted July 18, 2019 String theory is a mathematical model . It hasn't been proven and I guess it will never be . Also it tries to combine general relativity with quantum mechanics which is wrong , due to the nature of quantum mechanics (Quantum mechanics describes the possible outcome of our universe and general relativity describes something which is already a part of our universe) . Well I guess QFT is wrong as well for the same reason but physicists stubbornly dont listen to me .

Science uses theory, based on mathematical models, to describe our best supported explanations for various phenomena. Science doesn't deal with "answers" or "proofs". If we did, we'd stop looking when we thought we "proved" something, or that we finally had the "answer'. Instead, we constantly amass more and more evidence, constantly making our theories stronger and stronger, but we don't regard them as some final answer or proof. Because that would be really dumb. Religion often claims answers or proof, but science needs to remove as much subjectivity as possible in order to be true to its methodology.

AUDI R6 Posted July 18, 2019 Author Posted July 18, 2019 Wait a minute .... We write science from our observations in the nature and from experiments . So science cant be wrong . Math on the other hand are made from human logic . Human logic can be wrong but nature cant.
