      I don’t know so I asked google your question and this answer came up from NASA – I’m sure it’s better then anything I could come up with.

      I can’t give any more definite answer than Vicky, or indeed NASA, but let me add the following:

      In the wonderful words of Douglas Adams,
      ‘”Space,” it says, “is big. Really big. You just won’t believe how vastly, hugely, mindbogglingly big it is. I mean, you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space, listen…’.

      This great website, which you may have to access from home lets you scroll all the way from the very smallest things we know to the very largest: http://htwins.net/scale2/

      I don’t know the answer either sorry! In fact I don’t think anyone is 100% sure how big it is :/ You should definitely check out both of those websites tho! ^^^ They’re awesome 😀

      BIG! probably bigger 🙂

      Actually I think we cannot know for sure as the Universe is expanding at a velocity higher than the speed of light. So parts of it are outside or event cone and we cannot see them. How big this unknown part of the Universe can probably be estimated from the age of the Universe and assuming some model of the very early stage of the Universe.
