Physical universe:

The universe is vast. The Earth we live on appears to be just  a speck of dust circling a small star in a remote corner of  an obscure galaxy. If  we are a speck in the immense space, we also occupy dnly an instant in the expanse of  time. The universe is also very old. We now know  that  it  is about fifteen or twenty billion years OM, while we, the human beings have been around for only two million years or so.

However, before we embark on this venture, we will give you an idea of the cosmic distances, so that you're  able to appreciate what follows.
