Two black holes and a particle.

Click For Summary

Discussion Overview

The discussion revolves around the behavior of a photon in the vicinity of two overlapping black holes, particularly focusing on the implications of their event horizons and the gravitational effects on the photon. The scope includes theoretical considerations and speculative scenarios regarding black hole interactions and photon behavior.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant proposes that if two black holes of equal mass have their event horizons touching, a photon shot between them may have an uncertain path, potentially entering either black hole randomly.
  • Another participant asserts that the black holes would coalesce into a larger black hole if their event horizons overlap.
  • A different viewpoint suggests that the gravitational forces from the two black holes could cancel each other out, allowing the photon to remain stationary between them, with a theory proposing that this could lead to the photon acquiring mass.
  • Further questions are raised about the specific theory that suggests a photon can have mass and the consequences of the black holes' points coming together.
  • One participant references a source that discusses electromagnetic forces potentially forming a stationary wave, which could relate to the mass of the photon, indicating some uncertainty in understanding the concept.

Areas of Agreement / Disagreement

Participants express differing views on the behavior of the photon and the implications of overlapping black holes. There is no consensus on the outcomes or the theories involved, indicating an unresolved discussion.

Contextual Notes

Participants mention various theories and concepts without providing definitive explanations or consensus on the validity of those theories. The discussion includes speculative elements and assumptions that remain unverified.

I was going to post this in the cosmology chat, but figured it belonged here more than there.

First I want to take two black holes of equal mass and then place them so that their event horizons are touching (or just overlapping - I'm imagining two spheres placed next to each other). Now what happens to a single photon (particle of any type will work) shot between these two black holes, what hole does it go in? Would it be entirely random? If you shot a stream would would half go in one and half go in the other?

What happens if event horizons of black holes overlap?

What happens if event horizons of black holes overlap?

The black holes would coalesce into one bigger black hole.
 
Without that fact, the photon would travel straight to the part of the black holes overlapping. The equal force of the gravity would cancel out, and cause the photon to remain stationary between the two black holes, and accoding to one theory, could cause it to turn into a small amount of mass.
Either I hit it on the nose or am totally ignorant.
 
Thanks for the answers.
And now for the follow-up ones.

1). What theory is it that says a photon will then have mass?

2). What happens when the 'points' of the black hole come together? Anything? Nothing? It seems that two objects like that pulling at each other would cause some problems.
 
I think I found it on www.howstuffworks.com. It's something like that the two electro-magnetic forced would become a stationary wave, and could be mass, I don't know, maybe I didn't understand it.
