ok, why only 'A' and 'B' types, there can be infinite numbers like 'C', 'D' ......'Z1', 'z29'.....and so on.
But only A and interact with gravity meant for 'A'
well i kinda get what they are sayin and i can believe in it. for those who dont know im pretty sure they are sayin there's some alternate universe which is where B resides, while we live in A, just like A Earth and B earth for example, but we are aligned just right.
This is from a newspaper article,
"Meanwhile, in a break from scientific discipline, the researchers
posed a fanciful question on one report: "Maybye we are made of type A matter, and there is another kind, type B (or WIMPS), that doesn't
interact with type A except by gravity. Could there be type B stars, type B planets -- even type B people?"
I think the discovery of WIMPS is the first of many discoveries that will eventually proove the existence of other realities out their.
