All proofs that Black Holes have real physical singularities make assumptions
about the nature of the matter inside and of certain light rays. It is shown that
there are such lines inside Kerr that do not satisfy these assumptions.
As an example to show that the behaviour inside the event horizon for real matter
is very different from the idealisation of empty Kerr we consider two slowly
rotating Black Holes collapsing to a single object. There have been many
different approaches used to calculate the collapse of two BHs to a single one.
We show that the best starting point is the Kerr-Schild form for a Black Hole.
This explains the unexpected accuracy of a calculation by Jose Rodriguez
for the first gravitational wave discovery, GW150914.
