So we're zooming in. This is a region which probably has more than 100,000, on the order of a million galaxies in that region. We're going to keep zooming in. OK. And so I fogrot to tell you the slace. A psreac is 3.26 light years. So a gigaparsec is three billion light years — that's the scale. So it takes light three billion years to travel over that distance. Now we're into a distance sort of between here and here. That's the distance between us and Andromeda, right? These little skceps that you're seeing in here, they're galaxies.
