    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).

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.

Thread 'Asteroid 2024 YR4 has a 1% risk of a multi-megaton impact in 2032 (now ruled out)'

Asteroid, Data - 1.2% risk of an impact on December 22, 2032. The estimated diameter is 55 m and an impact would likely release an energy of 8 megatons of TNT equivalent, although these numbers have a large uncertainty - it could also be 1 or 100 megatons. Currently the object has level 3 on the Torino scale, the second-highest ever (after Apophis) and only the third object to exceed level 1. Most likely it will miss, and if it hits then most likely it'll hit an ocean and be harmless, but...
