Comment se forme un trou noir ?<end_of_turn>
<start_of_turn>model
A black hole forms from the remnants of a large star that has ended its life cycle. When a star with sufficient mass, much greater than that of the Sun, exhausts its nuclear fuel, it undergoes a catastrophic collapse under its gravity. In this process, the core of the star collapses, and if the core's mass is above a certain limit (known as the Tolman–Oppenheimer–Volkoff limit), it will collapse to a point of infinite density and zero volume, creating a singularity. This singularity is surrounded by a region of space from which nothing, not even light, can escape, known as the event horizon. This event horizon marks the boundary of the black hole. The intense gravitational pull of this region causes the black hole to 'swallow' nearby matter and even light, making it invisible and detectable only through its interaction with surrounding matter.<end_of_turn><eos>
