Black holes and magnetic fields?

Click For Summary

Discussion Overview

The discussion revolves around the existence of magnetic fields associated with black holes, exploring the implications of gravity on magnetic fields during the formation of black holes. It also touches on broader questions related to black holes and the Big Bang, including the nature of gravitational fields and energy emissions.

Discussion Character

  • Exploratory, Debate/contested, Conceptual clarification

Main Points Raised

  • One participant questions whether a black hole would have a magnetic field, suggesting that gravity might destroy any existing magnetic fields during the collapse of a star into a black hole.
  • Another participant provides links to articles discussing black holes and plasma jets, implying that there may be more to the topic than initially considered.
  • A different participant expresses skepticism about the reliability of simulations related to black holes, comparing them to weather predictions, and raises a question about the expansion of the universe during the Big Bang in relation to black holes' gravitational fields.
  • Another participant critiques the representation of black holes in one of the articles, arguing that it misrepresents the nature of energy emissions from beyond the Schwarzschild radius.

Areas of Agreement / Disagreement

Participants express differing views on the nature of magnetic fields in relation to black holes, the validity of external articles, and the implications of gravitational fields during the Big Bang. No consensus is reached on these topics.

Contextual Notes

Participants reference external articles that may contain assumptions or interpretations not universally accepted. The discussion includes speculative questions about gravitational effects and energy emissions that remain unresolved.

Hey all,
Having stumbled across this forum completely by accident I thought I would stay for a while.
As such I have a question.

Would a black hole have a magnetic field?
I would assume that magnetic fields are affected by gravity and therefore any magnetic field would be destroyed when the star collapsed to form the black hole.
Any thoughts?

And hello all :)

Oh god. The first article says "This simulation process is similar to weather-prediction techniques" EEK.

If it's as accurate as weather predictions then I'm afraid it's really not telling us much :(One question I have about the Big Bang and Black holes.

If black holes are so massive that light cannot escape. In the Big Bang (virtually infinitely larger than a black hole) how did things expand with the potentially massive gravitational field it would create?
 
first of all the first article lik is poodoo. they make it sound as though once whatever ahs passed through the schwarzchild radius huge beams of energy go splirting out zillions of miles. nothing escapes the schwarzchild radius- except me
