Quasars - how do they emerge from black holes?

AI Thread Summary
Quasars are believed to emerge from black holes due to the immense energy released when matter approaches the event horizon without crossing it. This matter, often found in gas-rich environments like young galaxies, is torn apart as it nears the black hole, resulting in powerful jets that form quasars. The discussion clarifies that while nothing can escape a black hole once it crosses the event horizon, the energy from infalling matter can create observable phenomena like quasars. This process highlights the complex interactions between black holes and surrounding matter. Understanding this mechanism resolves initial confusion about the nature of quasars and black holes.

According to everything I've read and heard (as a non-scientist), nothing can come out of a black hole.

However, on a couple of documentaries I've seen on the Nat Geo channel in the last week, the astronomers talk about quasars as being massive jets that come out of black holes, because the black holes can't contain all the gas that gets sucked into them.

This doesn't make sense to me - if "nothing" can escape, then how does a quasar do it?

simple. the gas never enters the event horizon
 
Quasars are thought to originate in matter rich environments [very young galaxies]. Matter streaming into the central black hole is torn apart as it approached the event horizon releasing vast amounts of energy.
 
Thanks for your replies - I understand it now.
 

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 'Could fast radio bursts be alien radar signals?'

Both have short pulses of emission and a wide spectral bandwidth, covering a wide variety of frequencies: "Fast Radio Bursts (FRBs) are detected over a wide range of radio frequencies, including frequencies around 1400 MHz, but have also been detected at lower frequencies, particularly in the 400–800 MHz range. Russian astronomers recently detected a powerful burst at 111 MHz, expanding our understanding of the FRB range. Frequency Ranges: 1400 MHz: Many of the known FRBs have been detected...
