On Reality and the Real World

Abstract

Roughly speaking we get our conviction about the existence of the so called real world by means of three ways: The direct information of our senses (and the detection devices), the information we get through media and literature, and the information we get from the various theories which try to describe the real world. On the other side we also learn by experience that such information means are more or less fallible. This fact generates, among other things, the problem of the validity of the information we receive and assimilate, and the problem of the meaning of the existence of real-world-objects. In this paper, starting from some meaningful ‘facts’ and using the physical theories as a reference frame, I try to state and answer some of the questions related to the existence of the world − that is, about the existence of the objects of the world – , and the meanings of such statements and answers. It is the how-the-world-operates-vision and how such knowledge allows us to predict how our surroundings will function in the near and medium future.
