Are Magnetic Anomalies the Cause of Black Hole Eruptions?

    Black holes Holes
AI Thread Summary
The discussion centers on the understanding of black holes (BHs) and the potential role of magnetic anomalies in causing high-energy events in galaxy centers. Observations of BHs are primarily based on their effects on surrounding matter, with no direct observation of event horizons. While many believe in the existence of BHs, some argue that modifications to general relativity (GR) may be necessary to explain phenomena in strong gravitational fields. There is skepticism about fully trusting the black hole model until more rigorous tests of GR are conducted. The possibility of magnetic anomalies causing these eruptions is considered, but deemed highly unlikely compared to the established mass presence associated with suspected black holes.

That is the question real, how well do we understand the properties
of BHs, AFAIK observations are based on the effect they have on there
surroundings, and no one has actually observed an event horizon.
Given that something creates massive disturbances in the center of
galaxies, has everything other than BHs been ruled out?
and is the loss of information an bothersome part of BH theory?

Everything else that can be predicted by standard physical theory has been ruled out, as far as I know. If black holes don't exist, it's likely because a modification to GR is required in the strong field limit.

So even though we have observational evidence of some high energy
events in the center of galaxies, it is possible that they are not caused
by BHs if GR is in error?

That's right. I'm sure many of my colleagues would tell you that black holes are all but proven to exist, but I still share a bit of Einstein's skepticism on the validity of his theory in that regime. Nonetheless, something interesting is going on in those regions and my guess is that it can at least be approximated by a black hole at reasonable distances. I would be more willing to trust the black hole idea once we have more rigorous tests of GR in the strong field limit.

So would it be beyond the bounds of possibilities that these eruptions are
caused by magnetic anomalies?

No, but roughly as probable as ET landing in your back yard and Elvis jumping out. There is clearly a very large amount of mass centered on the location of suspected black holes.
 
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.
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.
