>>12193569>Nothing. Or rather never. Event horizon cannot form, nor anything can reach it in finite time (for outside observer, i.e. us).Incorrect, the event horizon is not a physical singularity. It simply takes longer and longer for light from the object approaching the event horizon to reach us, this doesn't mean that it never crosses.
>Universe will reach heat death or any other meme end long before infinite time passes and black holes would also cease to exist, so no, it won't be able to ever reach it eitherInfinite time is not required, it passes the event horizon in finite time. In fact we can tell when it crosses by timing how long each photon takes to reach us.
