There is nothing new about modeling reality. It has been put to practice sincehumans first invented toys. For children, toys mimic reality and possess manycharacteristics, taken from the real world. They help to understand complexities ofour world on simplified models, on simple replicas of some real, complex objectsand situations. The modeling in this brochure follows a similar scenario, analyzingreal objects and situations by using abstract and real models. With the help of thismodeling, this book ambitiously takes on revealing, or at least simplifying, some ofthe mysterious aspects of our existence on this planet.The modeling, used in this brochure, derives tangible guidelines, which lead toconclusion that our world is just a computer simulation or just a mere game, beingplayed in another dimension.Since computers and programming started many decades ago, I am well awarethat I am not the first person to suggest this comparison. There must be many ofus, puzzled by such close resemblance of our world and the virtual digital world.Especially, when towards the end of the twentieth century, the Object OrientedProgramming took off. Modeling of objects in our world into the digital world ofcomputers is revealing and tempting to draw parallels between these two.The most radical concept, described in this book, is based on refutation of specialtheory of relativity and the speed of light is curtailed to be constant only relative toits source. The light and time create an illusion in our mind what opens completelynew outlook on our world. Some conclusions also contradict generally acceptedbeliefs, like for example belief that a clock on a fast moving object slows down.The first edition of this booklet was meant to be just a guideline for generalpublic, to elaborate on the ideas raised and to create a qualified discussion. Astime has progressed I realized that I was asking too much.This booklet did not raised expected discussion and media and universities Icontacted, all of them but one, shied away without any response. The only remedyleft to me was to continue and elaborate on these issues myself. This sixth editionis therefore the first, combining most of the basic changes to this new concept intoa series of easily understandable steps.When reading this brochure you might undertake the same process of reasoningand you might draw the same conclusions. I do not ask you to believe what youfind here, though. All what I am asking, if I may, is to consider Ren� Descartes'undying legacy:"Cogito, ergo sum."(I think, therefore I am.)
