B Does Negative Mass Play a Role in Hawking Radiation?

AI Thread Summary
The discussion centers on the relationship between negative mass and Hawking radiation, questioning whether particles with negative energy also possess negative mass. It suggests that if negative mass exists, it would exhibit anti-gravity properties, complicating the dynamics of black holes. However, participants clarify that the concept of virtual particles in the context of Hawking radiation is a heuristic analogy and should not be taken literally. The notion that negative mass could influence the behavior of particles near a black hole is deemed incorrect. Overall, the conversation emphasizes the complexities of theoretical physics and the limitations of simplified models in explaining phenomena like Hawking radiation.

Recently I was actually stuck on a thought about hawing radiation.
If quantum fluctuations cause virtual particles to occur from space. So, to maintain the balance of mass in the universe, the particle with -ve energy should be having -ve mass, right?
If so, by Newton's equation of gravitation, it should be having anti-gravity properties when near a body with positive body.
For the body to fall into the black hole, at a certain point, the velocity of the -ve mass body should be greater than the velocity of light. So black evaporation would not be happening.
So does the body with -ve energy has -ve mass also?
If so, how will it fall into the black hole?

I am just in 10th grade, and I am asking this out of a bot of curiosity. I do sincerely apologize if it is wrong for wasting your precious time.:smile:

Not right. Also beware that the "virtual particle falling into the black hole" picture of Hawking radiation is a very heuristic one. As Hawking himself put it, it is the closest description in terms of English that he could think of. It is not a picture that should be used to draw any kind of inferences about what is going on.
 
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...
This hypothesis of scientists about the origin of the mysterious signal WOW seems plausible only on a superficial examination. In fact, such a strong coherent radiation requires a powerful initiating factor, and the hydrogen atoms in the cloud themselves must be in an overexcited state in order to respond instantly. If the density of the initiating radiation is insufficient, then the atoms of the cloud will not receive it at once, some will receive it earlier, and some later. But then there...
