Black holes have the same mass and information as the stars that formed them.

Unless the theory also breaks mass and information conservation, the star that gave birth to our black hole must have been as massive as our entire universe.

I doubt we have any theory how a star that size can have formed.

I meant apparent mass. Just dropped the apparent because we're on HN and anyone familiar with relativity is likely going to know what I mean. I mean if actual mass went up we'd be violating conservation of energy. It's all about your frame of reference and you can treat these things as local systems.
