    You will get several answers -- based on different measurements. The one I like is that it is at least 250 times bigger than our visual horizon which is 13.7 billion light years. Meaning the curvature is virtually flat--

    and that the visual; horizon must now be out about 95 billion light years, since the light we can see has been travekling toward us for 13 billion years while the universe has been expanding.

    clear skies!

    The easy answer is that nobody knows. Nobody has ever reached the edge, and any estimates are purely speculation. There is still much to learn about the earth, and we live on it

    Edit: Unless you are talking simply how big is our small little galaxy is. I was assuming you meant the entire "Universe"

    The universe is Infinite in size!
    If the universe is bounded, then what will you call the space beyond this boundary?
    simple thought :-)
