The kind of bagel that ruins lesser bagels for you.
Summary
A new paper accepted to Physical Review Letters proposes that the gravitational wave event GW231123, which detected two black holes too massive to have formed from stellar collapse according to current models, may have originated from primordial black holes born in the early universe. The researchers suggest these black holes could have grown over billions of years by accreting matter, eventually becoming the record-breaking massive objects detected in 2023. This challenges conventional stellar collapse models and opens up new possibilities for understanding black hole formation.
