We show that Lubin--Tate theories attached to algebraically closed fields are characterized among $T(n)$-local $\mathbb{ E}_{ \infty}$-rings as those that satisfy an analogue of Hilbert's Nullstellensatz. Furthermore, we show that for every $T(n)$-local $\mathbb{ E}_{ \infty}$-ring $R$, the collection of $\mathbb{ E}_\infty$-ring maps from $R$ to such Lubin-Tate theories jointly detect nilpotence. In particular, we deduce that every non-zero $T(n)$-local $\mathbb{ E}_{ \infty}$-ring $R$ admits an $\mathbb{ E}_\infty$-ring map to such a Lubin-Tate theory. As consequences, we construct $\mathbb{ E}_{ \infty}$ complex orientations of algebraically closed Lubin-Tate theories, compute the strict Picard spectra of such Lubin-Tate theories, and prove redshift for the algebraic $\mathrm{ K}$-theory of arbitrary $\mathbb{ E}_{ \infty}$-rings.
