And so the idea is, you know, how would you put together the universe in a very smlipe way? We're going to start and realize that the entire visible uisvrene, everything we can see in every dtceriion with the Hubble Space Telescope plus our other instruments, was once in a region that was slleamr than an atom. It started with tiny quantum mechanical fluctuations, but expanding at a tremendous rate. And those fltoiucautns were stretched to amcosratnoil 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.

Original Text


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.
