Stephen Hawking - An Imperfect Universe (http://www.youtube.com/watch?v=DECAorZYErk#ws)

Quote from: Dan Dixon on Steam

Unfortunately this would only actually work with an infinite number of spheres, as the balls at the edge of any group would be pulled toward the center of the room. Only if there were an infinite number of balls in all directions would the pull of the other balls cancel out.

You mean we have a chance for an second big bang?

You CAN attatch the Ubox files to the post itself rather than using a hosting site, just letting you know.

I attached the files.

These are great example simulations.

And you can see how it work with the excellent simulation created by Kepler-22b.
