Algebraic hyperbolicity of very general hypersurfaces in projective spaces

We prove that a very general sextic threefold in $\mathbb{P}^4$ is algebraically hyperbolic, settling the last open case and completing the classification of algebraic hyperbolicity for very general hypersurfaces in projective space. The proof follows the Coskun--Riedl scroll construction, with the moduli of stable maps and the geometric canonical height as new ingredients.

Threefolds containing all curves are rationally connected

Any smooth projective curve embeds into $\mathbb{P}^3$. More generally, any curve embeds into a rationally connected variety of dimension at least three. We prove conversely that if every curve embeds in a variety $X$, then $X$ contains a rationally connected subvariety of dimension at least three. In particular, "all curves embed" is a birational property for threefolds.
