* Issues: Gravity in 5D
braneworld backgrounds often exhibits problematic features, including
kinetic ghosts, strong coupling, and the van Dam-Veltman-Zakharov (vDVZ)
discontinuity, which are an obstacle to producing and analyzing models
with interesting and potentially observable modifications of 4D gravity.

* Radiation: Scalars, fermions
and vectors radiate on the brane, while gravitons radiate in all directions,
and the number of possible helicities D(D−3)/2 grows
with D, so they lead to a higher evaporation rate in higher dimensions.

* Idea:
On scales r \(\ll\) R, the force goes like
F ~ r−(n+2);
On scales r \(\gg\) R, it goes like F
~ r −2.
