Halo Collapse Cascade Theory (HCCT): Early Supermassive Black Hole Growth
I propose a model for how early supermassive black holes formed much faster than standard growth models predict.
In the early universe, dark matter halos formed first and created Deep gravitational wells. Dense gas in these halos may have collapsed directly into massive black hole seeds, bypassing normal long star formation.
Growth then accelerated through:
• frequent galaxy mergers funneling gas inward • sustained gas accretion in dense early environments • repeated black hole mergers adding mass in jumps
Early supernovae and kilonovae likely helped redistribute and recycle gas, indirectly supporting further accretion.
This creates a “cascade” of collapse + merger events that could explain extremely massive early quasars like TON 618.
As the universe expanded, merger rates and gas supply dropped, slowing growth.
Thank you for taking your time to read this theory.
