Perfect spheroids are favored by any natural process that involves a great deal of surface energy. A sphere has the lowest ratio of surface area to volume, so the best way to minimize surface energy is form a sphere.

Correct. When I was a kid I remember listening to someone on Long John Nebel's radio show talking about similar "perfect metallic spheroids of alien origin" but I think these were in Czechoslovakia or thereabouts.

I used to love to lie in bed late at night listening to Long John Nebel, but he also used to weave stories about the Empire State Building slowly turning on giant ball bearings, and the wick farms where the highest quality candle wicks were grown. I think his best shows may have been the annual Halloween seances in an effort to contact Harry Houdini. Nebel was a true classic and a great story spinner. He had me half believing the Empire State Building story for a few weeks.
