Is there life out there? A reminder of Star Trek and Star Wars. There universe is abundant with intelligent life, names like Ewocks, Klinons, volcons, wookies Fenengi to. Quantum physics has it's own idea. Cosmologists tell us a string theory is the closest theory they have to the make up of the universe. It tells us evidence particles of the atom made up of vibrating strings in ten different dimensions.  A TV series called the sliders introduced ardencies to the dimensions of parallel universes. Inventions and discoveries are discovered by accident tweaking with inventions all the time. It happened to a university student Quinn Mallory experimenting with antigravity in his basement in an attempt to revolutionize heavy lifting. Instead he got more than he bargained for. His experiment produced somthing else. It had managed to reproduce the holey of cosmology an artificial wormhole. Theoretically a wormhole is the gravitational field right in the center of a black hole ( singularity ) shrinking space into a deep well. The vertically steep well links with another one clear across the other side of the universe creating a space tunnel. Mallory had created a portal to different dimensions on earth. They are the same earth's same time but alternate time lines dimensions. Each earth is 90 percent identical, the reaming ten percent is what makes them different. The British TV series Doctor Who got in on the act is an example of the concept. Several episodes played it out with a double of himself and one of his assistance's double from a parallel universe reminds us the world of sci-fi parallel universe dimensions.  Humans in theses dimensions have identical DNA with a slightly different personality make up. In theory every possible thing and circumstances lucky chances and our decisions from birth to death is playing out right now in theory infinite possibilities in parallel with our reality. In our world fate had played out Hillier's life the way all the Hitler biographies tell it like it is. In many parallel world histories Hitler's double's lives were very different his exact DNA double but not necessary the identical personality trait as each other. There are millions of dimensions successful and talented Hitler artists. Many dimensions can potentially have famous landmark buildings and structures that bears his signature and styling often bearing his of his name and many case all over the world. In the theory of many divisions to our personal time line history our doubles should be leading totally different lives than ours. Using Hillier as an example lead a totally different life in this world compared to an alternate life as a famous artist architect or some other profession in many many alternatives. There is a infinite number of alternate realities. While some of us are single others are married with children in various different careers while others not famous and some are, while others are drop out nobodies all living at the same point in time. To clearly show in a extreme example of the different lives of us doubles lead the possibility of Hitler's family for example moving to America for a better life were part of the 1500 souls that went down with the Titanic.  There are many alternate Julius Cesizer to Albert Einstein's. Heretically a lot of Hitler's doubles weren't so lucky to world war one. There is little a known story a Australian sniper serving in the Western front had Hitter dead in the cross hairs of his scope. Next second the sniper had to release his finger because Hitler had moved, There was no clear shot saving his life.   Many Australian sniper doubles got him. Many others did not. In many ways, fate can dish out many complex lucky and unlucky escapes in many dimensions at the same time serving in the first world war. In other words as far as the dimensions of the cosmos is concerned all the Hitler doubles were dead and alive at the same time.  It is the concept of a thought experiment thought up in this dimension, ( at lest ) by a German Physics called Schewdgener's cat that portrays a hypothetical odds of many of our doubles ( and when I say our doubles yes I do mean you and me ) are dead while others ( like us and our doubles ) are still alive in the many other dimensions including you and me as doubles to the other dimension doubles to this day. Schewdgener's cat principle is a part of quantum physics entanglement theory. The term entanglement in Quantum theory happens to be the very meaning of the word in context. Me and you and all our doubles lives are all entangled together by our DNA in the dimensions of the cosmos. Particles of the atom are identical clones throughout the entire universe, no matter were they are. Atoms of the sun are the same atoms in every other stare even clear across the other side of the universe. A clear idea liken to a dozen identical basket balls in one shop identical balls elsewhere in others all over the country. They are all the same no matter where they are. Theoretically what an atom does this side of the universe there are cloned particles clear across the other side as well. All the characteristic behavior of every particle the entire universe is uniformly the same. What atoms do in this side of the galaxy atoms are equally working clear across the other side too.  This means odds of an action in this side of the universe has a similar chance of a similar effect the other side. The word entanglement describes the entangled lives of the atoms of the universe including us and our doubles entangled with us. Enchantment theory came about from a simple question. What if a person in our world changed our worlds history traveling back to world war one making sure Hitler was killed then returned to the present? What would happen to the timeline we remember? Where does all the historic events remember go? There is a disastrous clash of time lines. Another time traveler goes back to the past to make sure Hitler lives altering the time line again. Theoretical in the world infinite possibilities our time line can be changed time and time again. Our time line is not fixed but variable. It can be changed to different time lines as many as infinite. One scenario I can think of is like a computer reboot that happens in each dimension. If the stored operating system memory recovery sequence is anything to go by, the person might be creating a parallel dimension instead of the original time line. The original keeps it's original time line that was meant to be. The original Hitler is not killed in the original while a reboot copy started a new time line at the point Hitler died carrying on leaving him dead and our own Hillier alive. This my be what prevents cranial time traveler interference. From our point of view of a visitor from the future is different from the visitor's point of view of us as a person from the past. So what influences your decisions in the present will depend on the view we are a person of the past. The person of the future is changing the past point of view but ( as you won't know it ) you will be changing the future of what you was supposed to have done the changing your fate to a new angle to your life you was never supposed to have done.  The view point of the person seeing the present as his past and the future visitor as things that haven't happened to us yet are in parallel with each other. The 1960 and 2003 time machine was a point of view of a visitor from the past point of view of the future.
