Samuel Grall and
Alexander Le Tick the University of Maryland simulated a scenario in which the
orbit of the black hole is placed satellite circling it with the same speed
with which rotates itself a hole - so that the two objects remain fixed
relative to each other.
Thus, they reproduce
the conditions under which for those in the motion of the black holes can test
the hypothesis made earlier by Stephen Hawking to the contingent of static
black holes.
