I have recently read some hard science-fiction story based on an assumption that if time stops (from external observer's perspective) on the event horizon of black hole, then in an anti-matter black hole's horizon the time would pass infinitely fast (same perspective)
I thought it was impossible, but I'm not sure anymore.
What would be the effect of approaching the event horizon of an anti-matter black hole?
Is it possible that an infinity of time passes in a finite time (from our point of view) ?
Fun follow-up: if so, can a result of infinite computation be returned to our timeline?
