Why Black Holes Have A Size Limit

How big can a black hole grow? Einstein's equations tell us that a black hole has no size limit. But due to the innermost stable circular orbit (ISCO) and self gravitation... its likely that ultramassive black holes like TON-618 are at the very limit of what is possible for a black hole growing by accreting matter alone. In this video we explain why this is the case. #sia #space #blackhole Thanks for watching and always happy to read your comments down below.
