    ... Can't get much bigger than this.

    By the way, the Big Bang was neither a bang nor explosion, since the universe expanded at the same rate as the energy expansion. It was technically an adiabatic expansion, and not an explosion.

    http://www.sciencedaily.com/releases/2008/04/080410200302.htm

    Update:

    It's amusing in the world famous particle physicist Steven Weinberg's 1976 book, The First Three Minutes, the whopping figure he gave for the average density of the universe at 1/100th of a second after zerotime, at 100 thousand million degrees Centigrade:

    4 thousand million (4 x 10^9) times that of the density of water.

    The electromagnetic light formed within this small time was FAR, FAR too energetic for visible light to appear.

    I remember reading about that a couple weeks ago. It could have been viewed by the naked eye, if you happen to be looking at the right spot. Absolutely incredible. Fascinating to see and read about, but wouldn't want to be on the business end of one of those.

    There is only a photo at the link.

    It's only a bright dot that could be seen during a clear daylight sky recently.
