The universe is a vast expansion of space containing all types of space matter. The basic forms of matter include stars, nebulae, planets and asteroids. While the exact age of the universe remains unknown, it is estimated that it is approximately 14 or 15 billion years old.
The steady state theory claims that the universe is constantly expanding, creating new galaxies and other stellar objects. While most galaxies are to far away to research, learning about the Milky Way can give us ideas about how the rest of the universe works.
