Let $G$ be the ring of the stable homotopy of spheres with the compositional
multiplication.
Does there exists an element $x$ of $G$ such that $xy=0$ for all $y$ in $G$?
Simpler question: is there a sequence $a_n, dim a_n>0$ of elements of $G$ such
that all the products $a_1 \cdots a_k$ are non-zero?
