Cosmological Musings

"I'm going to make a rocket that will go to the sun!", said Dominic.

Daddy:  But the sun is very hot.  The rocket will melt.

Dominic: This rocket is very strong. It will not melt.

Daddy: (Teasing) What if the sun runs away just before the rocket arrives?

Dominic: (Getting the joke)...or what if the sun is a balloon and it pops when the rocket hits it?....or what if the sun is made of rubber, and the rocket bounces back to earth when it hits the moon?...or what if the sun is really as small as a coin?....or what if the sun opens its mouth and eats the rocket?

Pia: (chiming in) What if the rocket hits the sun's eyes?
