What Is the Composition of Black Holes?

AI Thread Summary
The composition of black holes remains uncertain, with discussions focusing on whether they consist of matter, antimatter, or energy. The "no hair theorem" suggests that black holes are characterized solely by mass, charge, and angular momentum, making them indistinguishable regardless of their origin. Quantum loop theories attempt to address the singularity issue but do not provide clarity on galactic black holes. Questions arise about the fate of matter within black holes, particularly regarding Hawking radiation, which remains a conjecture yet to be experimentally validated. Overall, the nature and composition of black holes continue to be a significant mystery in astrophysics.

what is the composition of black hole?
is it a matter or antimatter or energy?
 
Astronomy news on Phys.org
According to the well-known "no hair theorem", from the point of view of an external observer, a black hole has mass, charge and angular momentum and no other physical properties, so for example a black hole formed from antimatter would be indistinguishable from one formed from matter.

AFAIK, no one knows what a black hole (is) quantum loop theories try to circumvent (the) singularity, and as yet, all so AFAIK they have nothing to say about the galactic black hole.

Were can the stuff in a black hole go if it is not eternally locked up in space time?
Hawkings radiation, a so not tested conjecture.
 

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 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Can the signal WOW be explained by the maser effect?'

This hypothesis of scientists about the origin of the mysterious signal WOW seems plausible only on a superficial examination. In fact, such a strong coherent radiation requires a powerful initiating factor, and the hydrogen atoms in the cloud themselves must be in an overexcited state in order to respond instantly. If the density of the initiating radiation is insufficient, then the atoms of the cloud will not receive it at once, some will receive it earlier, and some later. But then there...
