Is Gamma Ray Emission from a Black Hole Really Possible?

AI Thread Summary
Gamma rays can be emitted from regions surrounding black holes, specifically from the accretion disk rather than the black hole itself. While gamma rays are composed of massless photons, they can still be produced in high-energy environments near black holes. The discussion highlights a common misconception that gamma rays originate directly from within the black hole. The relationship between gamma rays and the mass surrounding the black hole remains unclear, prompting further inquiry into the mechanisms behind gamma-ray bursts. Understanding these emissions requires a deeper exploration of astrophysical processes rather than a direct connection to the black hole's event horizon.

I just can't comprehend that gamma ray can come out of a black hole. Gamma rays are electromagnetism which contain photons, but photons have no mass. And we all know that a black hole swoops up light as well. And what recaton has the gamma ray on the mass around the black hole? I know It's true, we all know, but there's something I'm leaving out here. But what?

First, it doesn't 'come out' of black hole. It comes from the accretion disk which is 'outside' the black hole.

I'm not sure about the effect it has on mass around, though this http://en.wikipedia.org/wiki/Gamma-ray_burst_emission_mechanisms" might help in some way. Please let me know.

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

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.
