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.
 
Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...
3I/ATLAS, also known as C/2025 N1 (ATLAS) and formerly designated as A11pl3Z, is an iinterstellar comet. It was discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) station at Río Hurtado, Chile on 1 July 2025. Note: it was mentioned (as A11pl3Z) by DaveE in a new member's introductory thread. https://www.physicsforums.com/threads/brian-cox-lead-me-here.1081670/post-7274146 https://earthsky.org/space/new-interstellar-object-candidate-heading-toward-the-sun-a11pl3z/ One...
