Black holes and magnetic fields?

AI Thread Summary
Black holes do not have a traditional magnetic field due to the collapse of the star that forms them, which disrupts existing magnetic fields. The discussion raises concerns about the accuracy of simulations related to black holes, comparing them to weather predictions, which are often unreliable. Questions are posed about the relationship between black holes and the Big Bang, particularly how expansion occurred despite the immense gravitational forces involved. The conversation also critiques the portrayal of energy emissions from black holes, emphasizing that nothing escapes the Schwarzschild radius. Overall, the thread explores the complexities of black holes and their interactions with magnetic fields and gravitational forces.

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

Thread 'Asteroid 2024 YR4 has a 1% risk of a multi-megaton impact in 2032 (now ruled out)'

Asteroid, Data - 1.2% risk of an impact on December 22, 2032. The estimated diameter is 55 m and an impact would likely release an energy of 8 megatons of TNT equivalent, although these numbers have a large uncertainty - it could also be 1 or 100 megatons. Currently the object has level 3 on the Torino scale, the second-highest ever (after Apophis) and only the third object to exceed level 1. Most likely it will miss, and if it hits then most likely it'll hit an ocean and be harmless, but...
