A history of the world in funny puns

Once a pun a time . . . it all started with THE BIG BANG, a theory which describes how the Universe began in a rapid expansion about 13.7 billion years ago.
 It is thought that all of space was created in this first moment.
 Expert and scientist Stephen Hawking  has even appeared in a cameo for American sitcom The Big Bang Theory.
Here are some space puns:
 • How does the Solar System hold up its trousers? With an asteroid belt
• What kinds of music do planets sing? Neptunes
 • An astronaut broke the law of gravity and earned a suspended sentence
• That was a poor joke about infinity – it didn't have an ending
