      Sorry bobo – I don’t know very much about astronomy so I can’t answer your question.

      The observable universe is HUGE, 93 billion light years in diameter. However, that is just the bit we can see. That might be everything there is, or it might be a LOT bigger. It is even concievable that the universe is infinite in size! There are lots of different ideas, but at the moment, physics hasn’t fully resolved the question.

      The universe holds everything that has ever existed or will exist. Our best measure of the age of the universe is around 13.7 billion years, with a diameter of around 93 billion light years. So – VERY BIG!

      Enormous!

      Sorry I can’t give a better answer that that, I don’t know anything about astrophysics.
