Universes
What is a universe anyway? Everyone knows about the Physical Universe, but what about others?
Close your eyes. What do you see? If its other than the back of you eyelids, its probably not the Physical Universe. If you daydream and see images and scenes, or dream at night, where are these objects you see? They are not in the big P.U.
So let's see if we can define a universe. First you need space. This is a matter of dimensions. If only one dimension your universe would be existing in a line. Pretty boring I would say. Or if only two dimensions your universe would be a plane. Edwin Abbott wrote a book called Flatland about such a universe, and the prejudices and politics therein. We seem to be most comfortable with three spatial dimensions. I think a universe should have at least three to make it interesting, don't you?
OK, now we have space of a few dimensions, but what next? There is nothing in the space. We need objects, things, to view in our space. Otherwise, what's the point of having space. So we put things in our space that are interesting to view. Perhaps a few castles made of sand.
But there is one more missing ingredient. Now many in the past have gotten all philosophical about this point, but I think part of our universe is having someone who can view the objects in the space. Its has been debated whether if there is no one to view something whether it exists or not. The strict materialist would say that the thing exists whether or not anyone ever views it, makes no difference. But Quantum physics has resolved this issue. It has been repetitively proven that it does make a difference when someone views a object. The results in quantum experiments vary depending on whether there is an observer. So I am going to stick with requiring a being to be a viewer or assume a viewpoint in our universe. Perhaps there is a multiverse (many coexistent universes) out there, as many quantum scientists believe, but the one we are creating has been selected to be viewed by us.
So there you are. That's how to create a universe. Now notice that there weren't any laws specified on how objects behave in this universe. Or even if or how solid the objects are. That's up to you to decide. Have you noticed while daydreaming, or night dreaming, that often the rules are very different? Different universes can have wildly different laws. You can even make them up as you go along.
So have fun. I hope there are many more universes in your future.
