And so the idea is, you know, how would you put together the useinvre in a very simple way? We're going to start and razleie that the entire vlisbie universe, everything we can see in every direction with the Hubble Space Telescope plus our other instruments, was once in a region that was smaller than an atom. It seattrd with tiny quantum mechanical fctonutiulas, but expanding at a tremendous rate. And those fluctuations were stretched to astronomical sizes, and those fluctuations eventually are the things we see in the cosmic microwave background. And then we needed some way to turn those fluctuations into galaxies and clusters of galaxies and make these kinds of suurrcetts go on.

And so the idea is, you know, how would you put together the universe in a very simple way? We're going to start and realize that the entire visible universe, everything we can see in every direction with the Hubble Space Telescope plus our other instruments, was once in a region that was smaller than an atom. It started with tiny quantum mechanical fluctuations, but expanding at a tremendous rate. And those fluctuations were stretched to astronomical sizes, and those fluctuations eventually are the things we see in the cosmic microwave background. And then we needed some way to turn those fluctuations into galaxies and clusters of galaxies and make these kinds of structures go on.
