Understand

We perform numerical simulations of the gravitational collapse of a k-essence scalar field.

When the field is sufficiently strongly gravitating, a black hole forms.
However, the black hole has two horizons: a light horizon (the ordinary black hole horizon) and a sound horizon that traps k-essence.
In certain cases the k-essence signals can travel faster than light and the sound horizon is inside the light horizon.
