-This video illustrates the scaled size of our universe from quarks to the entirety of the observable universe. Each circle used in the video represents a scale factor of 10; meaning each larger circle is zoomed out 10x more than its predecessor.
( i.e. after 1 circle you are now looking at 10x larger horizon, after 2 circles 100x, 3 would be 1000x, and so forth. This also applies to the speed, ignoring relativistic effects, at which the observer (you) would be traveling.)
EDIT: Please note that the zoom out from 2:26 - 2:34 is a simplistic model of the *hypothetical mutliverse intended to aid conceptualization of the idea, but is currently not definitively known to science and is most certainly NOT part of the observable universe. I left some comments explaining why I kept it in the video for those who still aren't satisfied with this explanation. Thanks and enjoy!
***IMPORTANT INFORMATION UPDATE***:
In October of 2016, NASA has conducted another deep field survey with Hubble and found that the already unfathomably large observable universe actually has.... about 10x more galaxies than we originally thought, putting the new estimated total at around 2 trillion. That means that there are more galaxies in our viewable universe than there are stars in our own galaxy, by a large margin. And remember, this is all just the parts of the universe we can see. Much of it is obscured behind a cosmic horizon where the light cannot reach us. Truly astounding.
