Query: Is super-Planckian physics visible? -- Scattering of black holes in 5
  dimensions   It may be widely believed that probing short-distance physics is limited by
the presence of the Planck energy scale above which scale any information is
cloaked behind a horizon. If this hypothesis is correct, we could observe
quantum behavior of gravity only through a black hole of Planck mass. We
numerically show that in a scattering of two black holes in the 5-dimensional
spacetime, a visible domain, whose curvature radius is much shorter than the
Planck length, can be formed. Our result indicates that super-Planckian
phenomena may be observed without an obstruction by horizon formation in
particle accelerators.
