Escape from Two Black Holes? Solve the Mystery!

Click For Summary
SUMMARY

The discussion centers on the theoretical scenario of escaping from two black holes, referred to as BH1 and BH2. Once an object crosses the event horizon of a black hole, it cannot escape, regardless of the presence of another black hole. The conversation highlights that a second black hole cannot simply appear to create an escape route; rather, it emphasizes that the merging of black holes leads to a single event horizon, trapping the object indefinitely. The concept of collapsing a black hole into existence through sufficient stress-energy is also mentioned, reinforcing the impossibility of escape once inside an event horizon.

PREREQUISITES
  • Understanding of black hole physics and event horizons
  • Familiarity with general relativity principles
  • Knowledge of stress-energy concepts in astrophysics
  • Basic grasp of accretion discs and their dynamics
NEXT STEPS
  • Research the implications of event horizons in black hole physics
  • Study the process of black hole formation and collapse
  • Explore the dynamics of accretion discs around black holes
  • Investigate the effects of multiple black holes in close proximity
USEFUL FOR

Astronomers, astrophysicists, and students of theoretical physics interested in black hole dynamics and the implications of event horizons.

Hello everyone,

Imagine the following situation:
  • You are inside the events horizon of a static black hole (called BH1)
    • Now, due to the bended space-time, your future points to be inside the event horizon until eternity (You will never be outside)
  • Now, a second static black hole (BH2), similar to BH1 "appears" (for whatever reason) in the nearby, outside the events horizon of BH1, and simetrycally positioned for me, comparing to BH1 center, So:
  • BH2 ----- Me ----- BH1
    • My question is: Is there a way that BH2 can bend space time in the opposite direction than BH1, in a manner that both effects are cancelled, or reduced in a manner that now I am outside the events horizon of any of the black holes? and now i could come back home safely
In other words, If I am symetrically positioned between 2 black holes (but in a manner that if one of them was not there, i would be inside the events horizon of the other one), can I escape from them?

Thanks in advance for your support witht this oneAerodyn

No. Once you are in an event horizon you are stuck there, no exceptions.

You cannot just "poof" a black hole into existence. You can "collapse" a black hole into existence if you have enough stress-energy in a sufficiently compact region. It appears that having accidentally stepped into the first black hole, you have also fallen into a collapsing dust cloud as that cloud has formed an event horizon and as that event horizon has swept past and engulfed you.

Possibly your eyebrows have been singed in the process. It can get crowded on an accretion disc.

In any case, you are now inside the newly merged single black hole.
