Gravitational waves hint at black holes born from failed supernovae

When the most massive stars in the universe die, they often detonate in fiery supernovae, dramatically blasting most of their matter into space. The remaining stellar cores collapse into neutron stars and, sometimes, black holes. However, theories suggest that some massive stars might die without a bang, instead directly collapsing inward to become neutron stars or black holes.
