Theory of Everything

    I have a question. Only 4% of the universe is observable, how can that be?

    By using an overly strict definition of 'observed'.

    This is not strictly true. 4% of the universe is made up of ordinary matter, 23% is dark matter and the rest is dark energy. We don't yet have a good understanding of what the last two are.

    Bear in mind that this does not have much to do with a Theory of Everything.
