massive stars detonate as supernovae and this can create stellar-mass black holes. When enough of these are present in a small volume of space, like the
core of a globular cluster, black holes can absorb each other and in principle, can grow to
several hundred times the mass of the sun. If there is enough matter
for a black hole to “eat,” it can grow even larger.
