0 an area in outer space that sucks material and light into it from which they cannot escape -- черная дыра
Now, imagine one of the particles were to cross the event horizon of the black hole.
The effect is often described as resulting from virtual pair production on the horizon of a black hole.
Then one of the particles is inside the black hole and one outside.

What if the universe is not slated to contract into a black hole or expand into nothing?
We assume that there is at most one black hole in the network.
The minimum number of agents capable of identifying a black hole is two.
Now it is possible to use the time-out mechanism to locate the black hole in any graph, with only two agents, as follows.
