Can Black Holes Actually Emit Radiation?

AI Thread Summary
Black holes do not emit radiation directly; instead, X-rays are generated by gas and dust in an accretion disk orbiting near the event horizon. This material heats up due to intense gravitational forces, leading to the emission of X-rays. Additionally, black holes can theoretically emit Hawking Radiation, a process predicted by physicist Stephen Hawking. This radiation occurs due to quantum effects near the event horizon. Understanding these mechanisms clarifies how black holes can be associated with radiation despite their nature of trapping light.

If nothing can escape black hole(not even light), how can it radiate X-ray?

Typically it is not the actual black hole that produces the X-rays. It is usually caused by gas and dust orbiting at extremely fast speeds close to but outside of the event horizon in an accretion disk. Even so it is still possible for black holes to 'emit' radiation as Hawking Radiation.
 

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...

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...
