Scientists can never be 100% sure that there theories and explanations for results are true, for example, the Newtonian physics is very different to quantum physics, its strange that different rules apply to matter of different sizes but all of which are in the same universe. Sometimes, somthing we have always believed to be true can suddenly be disproved by an experiment, so my question is this, do you think that there are some theorys in science that you dont completly agree with? Ideas that were just put in place because we cannot find a way of explaining the results? And do you think anyone will ever disproves certain theories, particlualy those from Einstein, Newton and other big named scientists?
