Dr Fred Alan Wolf, quantum physicist, suggested that quantum physics gives " a real mathematical basis for saying actions in the future can have an effect on the probability patterns that exist in the present." In other words, it is possible that insights that you are having in 20 years times are actually reaching back to have an effect on your present. To make absolutely sure that this happens, Dr Wolf suggested envisioning yourself out there in the future with something about yourself better than it is now. That vision would propagate back to the present, affecting the choices you make now so that you envision would come to pass. This means that quantum physics supports the validity of positive thinking and visualisation.
