I am a thirteen-year-old kid living in Australia. I have joined this forum seeking answers. I have recently read a book by the title "A short history of Nearly Everything". It has sparked a fascination of physics in my life. I would call myself a bright child. I am in extension or acceliration for all my subjects. Apart from maths I enjoy English. That brings me to why I am here. I have written several stories and short novels (none of them have been published of course) and several have won awards. Now I wish to write a book including my new found interest in physics. In A Short History of Nearly Everything there is a chapter that mentions electrons. A theory by a slightly eccentric physicist is that if one travels downwards into an electron he/she will find another universe in it. This universe consisting of all the same laws of physics as our own, thus meaning that there are electrons in their universe. So an infinite path can be followed down into electrons finding universe after universe. The same going upwards, meaning that we ourselves are just in a solar system in a galaxy in a universe that is just inside one electron of a universe above us. Now as you may obviously be able to see this is gold for an auther. Now all I need is a very simple explanation of an electron. One that explains its behaviour and location and of course its purpose. It also has to be understood by a thirteen year old. So if anyone could please help me I would much appreciate it.
