Please be patient while this page loads — it takes several minutes. But it does include, after all, the entire universe.
Click “Start,” and then use the slider across the bottom, or the wheel on your mouse, to zoom in — and in and in and in… or out and out and out… It will take you from the very smallest features postulated by scientists (the strings in string theory) to the very largest (the observable universe.)
The music just adds to the experience. Awesome.
I could spend hours on this!! :O
