“placed” in a single space $\R^4$. Assume that $F(x)$ is an elliptic cones with vertex $x$;  $F(x)$ is equal and parallel to $F(y)$, $G(x)$ is equal and parallel to $G(y)$ and $\tau_x=\tau : \R^4\to \R^4$ for all $x\in {\bf P}$ is a mapping such that $$\tau(F(x))=G(x),$$ $$G(x)=F(\tau(x)) \eqno(**).$$ As it follows from [@A; @Gu] the mapping $\tau$ is a classical Lorentz transformation. But if the relation (\*\*) is not valid, for example, $G(x)=\phi_x (F(x))$, where $\phi_x$ is a rotation on constant angle with respect to point $x$,   $G(x)\neq F(x)$, i.e. we have the flow of time (life) there where we see the present (death), then the theory of sets is useless.

Thus, the space-time ${\bf Set^P}$, which may be described as a Grothendieck topos [@Go], can no longer be “placed” in a single “space”.
