I don't know which aspect of it is more difficult to fathom, the small end or the large end.

On one hand, the thought that just the *observable* Universe is 93 million AU across is staggering.  Like, even moving at c to traverse that space would take like 800 million years.  Insane.

And then there's Planck length and Planck time - which if the theory is true, nothing can be shorter or take less time than either one.  I've always understood that to mean that reality is like a computer monitor in that it has a "resolution".  At some point, there are NOT an infinite number of points between point A and point B; even if it's mathematically conceivable to cut Planck length in half, it isn't fundamentally possible.  I'm like Kristen Bell with a sloth in the room, my brain wants to dissolve into jelly.

Funny how the scale ended short...

If you go past perceived universe, you get all the way out to theoretical universe, but then it stops.  If you zoomed out further yet, you'd see that all fits in the tip of Bill Copes's wang.

Dude forgot to put Betelgeuse in there.

But very cool site!

EDIT: Also, current theories suggest that spatially our universe is a manifold, and therefore has no "center."  It's like a gigantic, 3D game of Asteroids.
