Dear Friend,

• Stars rush out of control into the unbounded emptiness of space...forever!
• Entropy runs wild, undoing the painstaking work of eons!
• Giant black holes devour entire galaxies, while decaying protons explode like itsy-bitsy time bombs!

Sound like an appealing future to you? Yet this is exactly what will happen if enough matter to gravitationally close the universe isn't found...and soon!

For years, astronomers in the United States and all over the world have been searching the skies frantically for signs of 'dark matter' -- the MISSING MASS needed to bring gravitational closure to our universe. The search has been long, but ultimately fruitless. But now YOU can help!

If you or someone you love has any of the MISSING MASS, please send it to A.F.C.U. (Americans For a Closed Universe) today! A.F.C.U. will then send your MISSING MASS directly to the astronomers who have been seeking it so desperately.

Please take a moment right now to fill out the attached form and return it to A.F.C.U. We'll even pay the postage!

= = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

[_] YES! I or someone I love has some of the MISSING MASS. Please rush to the astronomers of the world my contribution of:

• [_] 1 kg
• [_] 10 kg
• [_] 10²⁴ kg
• [_] Other: _________________ kg

[_] I don't wish to contribute now, but keep me on your mailing list.
