SUMMARY
This discussion centers on the visual phenomena associated with the collision of two non-rotating black holes, specifically under the framework of General Relativity (GR). Participants explore the implications of gravitational effects on light and the merging of event horizons. It is established that as two black holes approach each other, their horizons will merge, but an external observer will not see them cross the event horizon due to the nature of light escaping from black holes. Instead, objects near the event horizon will appear to fade from view as the horizon expands.
