Gives you a little hint on the scale of space.

Make sure you try hitting the "C" in the bottom-right at some point.

Is the known universe 99.9999999999999999999958% empty? Or is it 0.0000000000000000000042% full?

1. WOW!!!

So cool

2. Another good demonstration is that if the Sun were the size of a bowling ball and you were

holding it, the Earth would be the size of a small marble about 100 feet away.

And the crazy thing is when the Sun becomes a red giant ~5 billion years from now, that little bowling ball will swell up so much that it will engulf (or nearly engulf) the marble 100 feet away.

3. That was great.

Although some of the comments were like "huh?"



I imagined the New Horizon spacecraft hurtling alone out in that silent void when it passes some gigantic white letters saying:

"Congratulations, you made it this far"


Any time now the 1st Voyager will pass a bunch of gigantic yellow letters:

"EPISODE VI
A New Hope
It is a period of civil war
Rebel spaceships, striking from a hidden base....."

4. All that vast emptiness....

and yet aliens from another galaxy come here to Earth....


.... to do intricate but plain ol' Euclidian plane geometry in barley while we're not looking!


Amazing!

5. The probes-don't forget the anal probes

Aliens must be saying, "This has gotta be where all those Republicans are coming from. Go deeper, Dr. Xylic"
