    Fusion Quasars
AI Thread Summary
Quasars are unlikely to generate energy from fusion due to the low density of material falling into them, which results in minimal fusion activity. The energy produced by the accretion disk surrounding a black hole far exceeds any potential energy from fusion processes. Unlike white dwarfs or neutron stars, black holes lack a solid surface for fusion to occur. Additionally, even though the Sun does not have a solid surface, its fusion processes are vastly different from those in quasars. Overall, the mechanisms of energy generation in quasars are primarily linked to their accretion disks rather than fusion.

Could quasars be generating energy from fusion? I mean with all that material falling on it...

Energy cannot be generated, only transformed. The density is too low to produce relevant fusion power - you always have a few atoms fusing, but that does not have any effect. The accretion disk releases much more energy than even a 100% fusion rate could do.

That "it" is presumably is black hole, which has no solid surface on which matter might fuse, unlike a white dwarf or neutron star

The sun doesn't have a solid surface either. Black holes have accretion disks (that's where the radiation comes from).
 

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?'

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...
