Ellis formulated his theory of what the universe and time must be like. In 2006 he began to formulate his own theory about time and the Universe. The theory he formulated is based on quantum physics rather than relativity, as Einstein's theory is based on. “A strange fact about quantum physics is that indeterminate future outcomes are apparently governed by the probabilities of the present. Quantum objects exist in "superpositions" of more than one state until the moment we measure them, when they adopt one or another of their possible forms. The best-known example is Schrödinger's cat: locked in a box with a vial of poison whose seal may or may not be intact, it is both alive and dead - until the box is opened, when it is definitely the one or the other. ”Ellis says that quantum physics allows for an objectively defined present. The present, in this theory, is the boundary between what our experiments have determined and what remains to be discovered. Ellis says we live on the edge of a “growing block universe.” The surface is what we call the present that takes us from one moment to another while quantum measurements are being made. Ellis believes that relativity can also define “now.” He says that Einstein's theory of relativity is a complete view of space-time and that space-time is warped by the presence of gravity. Ellis theorizes that “If we collected enough data and had a large enough computer, we could account for all the space-time distortions of all the galaxies, black holes, and other matter in the universe to calculate a 3D surface on which every point is positioned exactly the same age as where we are." According to Ellis “Space-time is defined until then and no further”, which means that the future is not set in stone... in the middle of paper..., and without any name, other than duration, which it is relative, apparent and a sensible form of “time”. Time in nature does not care how humans define or interpret it. We know that time cannot be “measured” because there is nothing of value to measure, but we know that the earth continues to spin and the sun continues to set and rise, and as humans we have transformed those truths about the universe into measurable natural values. systems we use to help us function as a society. The beauty of being human is that we can think, conceptualize and create. Mathematically, psychologically and philosophically time has always been a topic of interest, and although it may be difficult to define and understand, it is always around us in the form of a concept. Our society would function completely differently without the subjective and objective forms of time that we use every day.
