The questions of reality have always followed mankind, at least, throughout the last two centuries. Does reality actually exist or is it just a simulation of a higher form of life? Are we alone in the universe? Is there any way to travel from one period of time to another? Does time have a certain direction? Could parallel worlds actually exist? This paper tries to answer these and more based on the thematic questions. I also analyze and reckon other paradoxes of the quantum world. My reflections and some sort of proof are mostly based on quantum physics and philosophical ways of thinking. From the very beginning, I would also like to emphasize the importance of the fact that a considerable part of the musings is only probabilistic, due to the current inability of mankind to prove such kinds of things.
