the world of science, because of this Max Baron put it this way "it is possible for physics as we know it to be over in six months" because theories change so quickly that physics may not be where it is now in six months. Therefore I think that in the 21st exactly what will happen I cannot predict but from my knowledge I can tell you that theories will get proved wrong and new ones will be made and scientist will continue their drive to learn more about and understand physics....
