[ExI] scale of the universe

[Anders Sandberg]

I have some problems with the animation. It includes preons, which are 
completely hypothetical and have no real support. It gives a size for 
the neutrino, which I have a hard time understanding - they are believed 
to be pointlike, and if that is the spread of a wave packet it is too 
short. And the center of the universe thing is just a mistake.

Still, it remains one of the better animations in this genre despite the 
simple graphics. There are more nice-looking ones out there, but this 
one has a nice sense of presence by being fairly densely filled in.

Isn't that one of the saddest things? Worse, most people think the 
tupperware is more important.
