In this theory a filament of matter was drawn from the stars and coalesced into planets around one or both of them. In fact, this seemed to be the only theory taught!

My teacher, Mr. Pulaski, was a WWII vet, and was mightily impressed that I knew what the U in U-boat meant, and said it in German (unterzee). When I said that this theory meant that planets would be almost non-existent, he admonished me about the laws of.very large numbers: anything that CAN happen, WILL happen… and it will happen a lot! Never forgot that.
