How can black holes merge from our perspective, if something needs an infinite time to reach the event horizon from our perspective?

How can black holes merge from our perspective, if something needs an infinite time to reach the event horizon from our perspective?
- delecti 7y agoThe event horizon itself isn't really a "thing". The event horizons can merge without any "somethings" reaching any event horizon.
- fsh 7y agoBecause it doesn't take infinite time from our perspective. The object falling into the black hole experiences strong time dilation due to the extreme gravitational field, but that doesn't affect a remote observer.
- 7373737373 7y agoIn the twin experiment, the observer sees his twin age slower, so it _does_ have a remote effect. From the perspective of the object falling into the black hole, the local conditions do not change, time is progressing normally etc.
