From what I understand [1] the existence of exotic spheres in n>5 implies => the Smale conjecture is false in n>5 but does the Smale conjecture being false in n=4 implies nothing => about the existence of exotic spheres in n=4? [2]
Is not the main point of the article but the article cite another researcher saying that “Some archaea don’t even divide into two cells; they divide into three. There are many, many mysteries in archaea,” I googled it up couldn't but find it, any idea about it?
