Sizes of the Universe

Have you ever wondered how big the universe is? Maybe you've wondered how big Texas is in comparison to Pluto? Or how big an atom is compared to a microscopic organism. This infographic from Number Sleuth is intended to show you the size of the universe (and the things in it) by letting you to scroll down from the very largest known thing (the observable universe at the top) down to the very smallest thing (the hydrogen atom's proton nucleus) and see how different sized things in our universe compare to each other. Each row in this infographic represents a "level" and the blue funnel represents you zooming from one level to the next, going from larger to smaller.
