[ExI] scale of the universe

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.
