Discussion Overview

The discussion revolves around the merging of black holes, exploring how they crash into one another and the implications of such events. Participants consider the dimensionality of the universe and the mechanics of black hole collisions, including the roles of singularities and event horizons.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants propose that black holes can merge when they come very close to each other, resulting in a single, larger black hole.
  • There is a question about whether black holes collide at the singularity or at the event horizon during a merger.
  • One participant mentions that gravitational attraction is a force that brings black holes together, similar to how it forms stars and planets.
  • Another participant notes that while the universe has four known dimensions, additional dimensions may exist but do not influence black hole merging.
  • It is suggested that the event horizons of black holes merge first, with singularities potentially colliding afterwards, though this is not observable from the outside.

Areas of Agreement / Disagreement

Participants express differing views on the specifics of how black holes merge, particularly regarding the role of singularities and event horizons. The discussion remains unresolved with multiple competing perspectives on the mechanics of black hole collisions.

Contextual Notes

Some claims depend on assumptions about the nature of dimensions and the mechanics of black hole interactions, which are not fully explored or agreed upon in the discussion.

if black hole crash they unite to one b.h
here, how can this two crash??
universe has a lot of dimension so
i think it is hard to
and when they crash, crash with only singularity??

universe has a lot of dimension so
The universe has 3 spatial and 1 time dimensions, for a total of 4. There might be additional dimensions, but they don't play a role in black hole merging.

Black holes can merge, if they come very close to each other. They become a single, bigger black hole in this case.

one more..
when they collide they collide with singularity or in the event horizon??
 
The event horizons merge. The singularities probably collide/merge afterwards, too, but that cannot be observed from the outside.

gravitational attraction brings black holes together just the same as it brings cosmic dust together to form stars, planets, and black holes themselves...
