AI Thread Summary
The electric charge of a black hole is determined by the charge of the matter that formed it and is independent of its mass. From a distance, a charged black hole generates an electrostatic field similar to that of ordinary charged objects. A black hole with a significant excess charge will attract oppositely charged matter more strongly, leading to a neutralization effect. This neutralization process is not exclusive to black holes; it occurs in all charged objects, including stars and ordinary matter. Understanding these dynamics is crucial for comprehending the behavior of charged black holes in the universe.

How to find the charge of black hole?
Does charge depends on the mass of black hole?

The electric charge of a black hole is simply the sum of the electric charge that was on whatever matter formed it. It is independent from the mass. From a distance, it gives rise to the same sort of electrostatic field as ordinary charged material would at the same location. If a black hole had a very large excess electric charge of either sign, that would tend to make it attract matter with the opposite charge more strongly than matter with the same charge, which would tend to neutralize the excess charge.

Thanks for the info...Is this neutralization process happens only in black holes Or it happens in all e.g. stars,ordinary objects?
 

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b. I start this...
