  It's not observable by us, so we don't know. The figure is (to simplify) a deduction from what we can see, the observable universe, and the fact that we don't see any of the consequences that there would be in the observable bit if the entire universe were smaller. * https://doi.org/10.1111/j.1745-3933.2011.01040.x https://doi.org/10.1111/j.1745-3933.2011.01040.x
