There has been evidence of this in our own sun. One of the strangest is the multiple worlds theory. According to the multiple worlds theory every time a measurement is made that has even the slightest possibility of having two or more different outcomes the world splits into separate parts, one world for each possible outcome. If one believes this theory there can be an infinite number of universes. Another way that scientists are looking to explain the effects that they see in the quantum world is with string theory.
String theory says that there are long, one dimensional, strings that float around the universe.
Strings, according to the theory, make up all matter. These strings vibrate. Depending on the frequency that they vibrate, they look like different particles. When delving into this world, one must remember that it is nothing like our world, and that common sense does not apply. It is a strange world in which anything is possible except knowing exactly what is going on.
