Zoom from the edge of the universe to the quantum foam of spacetime and learn the scale of things along the way! Learn the size of the Pillars of Creation and marvel at the minuscule scale of a neutrino!

ARROW KEYS! ARROW KEYS! You can use arrow keys if the scroll bar is too sensitive.

Thank you so much for your high ratings and rave reviews!

Very cool

This is a very cool flash. The only problem with it (and it's a minor one, but I picked it up because I'm a physicist) is that the visible universe is not only 14billion Light Years Wide. Due to the expansion of space we can actually see 46.5 Billion Light Years on either side of us (ie. a sphere with a diameter of 93 Billion Light Years).

The thing you label "Estimated Size of the Universe" is not the estimated size, it's the actual size we can see. Outside of what we can see we don't have any estimations for how big the Universe is so there is no "True estimated size of the universe".

Other than that it's really awesome. Oh, it might've been nicer if the music looped better, it's pretty good now but a bit jarring when it finishes and starts again.

I never knew that

I can't believe the moon is actually smaller than the USA.

very intersting

lol what would have been fun is if you looped it get out the the largest scale and then if you zoom out more you end up looking at quantum foam again!

Who would've thought that the most effective brain-melter on Earth (Flash) could be used to make something...educational? Not me, that's for sure. I have hope for humanity's youth yet.

By the way, are you an idiot? Everyone knows that we ARE at the center of the universe!!!!!!!! :P
