## Unscramble the Blue Letters

So we have a model, and we can calculate it, and we can use it to make designs of what we think the universe really looks like. And that design is sort of way beyond what our original imagination ever was. So this is what we started with 15 years ago, with the coimsc Background eoxplerr — made the map on the upper right, which bascially showed us that there were large-scale fluctuations, and actually fluctuations on several scales. You can kind of see that. Since then we've had WMAP, which just gives us higher angular resolution. We see the same large-scale surcurtte, but we see additional small-scale structure. And on the bttoom right is if the satellite had fppeild upside down and mapped the Earth, what kind of a map we would have got of the Earth. You can see, well, you can, kind of pick out all the major continents, but that's about it.

So we have a model, and we can calculate it, and we can use it to make designs of what we think the universe really looks like. And that design is sort of way beyond what our original imagination ever was. So this is what we started with 15 years ago, with the Cosmic Background Explorer — made the map on the upper right, which basically showed us that there were large-scale fluctuations, and actually fluctuations on several scales. You can kind of see that. Since then we've had WMAP, which just gives us higher angular resolution. We see the same large-scale structure, but we see additional small-scale structure. And on the bottom right is if the satellite had flipped upside down and mapped the Earth, what kind of a map we would have got of the Earth. You can see, well, you can, kind of pick out all the major continents, but that's about it.
