GR: Black Hole - Electrical Charge

In summary: Charge is a property that does not decrease as black holes swallow matter. The statement is known as the "no-hair" theorem.

A GR? Does Acceleration or Gravity affect the force of electric charges?

Example: Material is forming a Black Hole
Heat is creating a ‘Cosmic Wind’ – that is blowing less dense matter away while denser matter is being favored for forming and enlarging the Black Hole.
And material is made up of positive Ions of very Dense make up, but Negative Ions are not dense, So their “fluffiness” is preventing them from going in.

Will the Black Hole acquire a “Positive” charge; Can the force of that charge be able to reach out of the black hole, start to push away more + ions, and overcome the ‘wind’ on the - ions: Thus keep it in a more neutral charge, avoiding an increasing charge.?

Experiment is our solar system:
A Large heavy plate is supported by insulated struts capable of measuring the weight of the plate without significant displacement of distance over another large plate.
On Earth the weight is 150 lbs when a measured charge is applied that lowers the weight to 140 lbs. Repulsive charge is supporting 10 lbs of the weight.

Taking the experiment to Pluto, our Moon, and Jupiter will give weights very close to 10 lbs, 25lbs, and 380lbs. When the same charge is applied should we expect the same 10 lbs change. Or should gravity have some small affect on power of charge to repel?

Charge is one of the few properties that isn't destroyed by black holes (the other two are energy and angular momentum). This is a statement of the so called "no-hair" theorem.

In any situation, charge is conserved. It is one thing for acceleration to affect the field due to a moving charge (yes) and another thing for the acceleration to affect the magnitude of charge (no, charge is strictly conserved)

Thanks - I guess at least some information can get out of a Black Hole.

FAQ: GR: Black Hole - Electrical Charge

What is a black hole?

A black hole is an astronomical object with an extremely strong gravitational pull that prevents even light from escaping. It is formed when a massive star collapses in on itself at the end of its life.

How does a black hole form an electrical charge?

Black holes can acquire an electrical charge if they are surrounded by an electrically charged environment, such as a charged gas cloud or a rotating disk of matter. The charge is generated by the movement of charged particles within the environment.

Can a black hole lose its electrical charge?

Yes, a black hole can lose its electrical charge over time through a process called Hawking radiation. This occurs when virtual particle-antiparticle pairs are created near the black hole's event horizon, with one particle falling into the black hole and the other escaping, resulting in a net loss of charge for the black hole.

How does the electrical charge of a black hole affect its behavior?

The electrical charge of a black hole can affect its behavior in several ways. It can influence the way matter falls into the black hole and can also affect the strength and shape of the black hole's electromagnetic field.

Can a black hole with an electrical charge be detected?

Yes, a black hole with an electrical charge can be detected through its interaction with electromagnetic fields. For example, charged black holes can emit jets of high-energy particles that can be detected by telescopes, and they can also produce electromagnetic radiation as they consume matter. However, the detection of charged black holes is still a challenging task for astronomers.
