Why can't negative energy virtual particles escape black holes?

Click For Summary

Discussion Overview

The discussion centers around the nature of virtual particles, particularly in the context of black holes and their interactions with gravitational fields. Participants explore questions regarding the escape of negative energy virtual particles, the simultaneous creation and annihilation of particle pairs, and the implications of quantum theories on particle behavior at the Planck scale.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • Some participants question why negative energy virtual particles cannot escape from black holes, referencing Hawking radiation.
  • There is a discussion about whether two sets of virtual particles can arise from the same point in space simultaneously, with some suggesting that if they are pairs, their existence would be largely independent.
  • Participants express uncertainty about the greatest energy a virtual particle can possess, noting that there may be no upper bound, though a cutoff could exist in a quantum theory of gravity.
  • One participant recalls from a course that the simultaneous creation of two sets of virtual particles is possible but less likely than a single pair, suggesting that all potential routes must be considered in probability calculations.
  • Another participant raises a question about the behavior of quarks and electrons at the Planck distance, inquiring whether they still interact through virtual photons as they do at larger distances.
  • A humorous post introduces a whimsical notion about particles "talking" and their emotional states, questioning the validity of such anthropomorphisms in physics.
  • There is a query about how to calculate the energy a virtual particle can "borrow," indicating a desire for clarification on this concept.

Areas of Agreement / Disagreement

Participants express a range of views and uncertainties regarding the nature of virtual particles and their interactions. There is no consensus on the questions raised, and multiple competing ideas are presented throughout the discussion.

Contextual Notes

Some discussions touch on complex concepts such as the Planck scale and quantum gravity, which may involve assumptions that are not fully articulated. The humorous contributions introduce a non-standard perspective that may not align with conventional physics discourse.

Who May Find This Useful

This discussion may be of interest to those exploring quantum mechanics, black hole physics, and the behavior of virtual particles, as well as individuals curious about the philosophical implications of particle interactions.

Why can't a negative energy virtual particle escape from a black hole?
Could two sets of virtual particles arise from the same point in space simultaneously? And would they have to annihilate simultaneously?
And how does a rapidly oscillating gravitational field affect virtual particle
creation and annihilation?
What is the greatest energy a virtual particle can possibly have?

Look up Hawking radiation.

Two sets? If you mean two pairs, then I suppose it's possible, and their existence would be largely independent.
What is the greatest energy a virtual particle can possibly have?
Currently there is no upper bound on their energies. It's possible that in a quantum theory of gravity there would be a cutoff at the Planck scale, but that's all hypothetical.

My turn: are these unrelated questions going somewhere?

Hmm... I seem to remember from a course on the standard model of particle physics that this is indeed possible - however its much more unlikley than the case of just one particle pair being formed. I think (and can only hope that someone wise will read this and correct it) that when you try to calculate the probalility of an event ocuring you have to take into account all of these less and less likely routes by which an event could occur?

Rothie M:
I would like to know, if quarks and an electron,in the early universe, separated by the Planck distance -10^-35 m - still absorb and emit virtual photons ,as they do at larger distances, in the current universe.
Loop quantum gravity theorists say that Einstein's laws were still valid at the Planck scale,so were other laws too?

When particles are separated by a distance comparable to the Planck distance, they can hear each other, so they keep talking about how stupid humans are. The laughing that results from those conversations is so strong, it tears them apart by a factor of several order of magnitudes. That is the reason particles are so sad. They cannot help talking about our stupidity, and it makes them lonely.

What I'm wrong !? How do you know ? Particles refuse to talk to us anyway.
 
Them soundwaves from those particles talking, were they doppler shifted by the Big Bang?
 
kind of relating to the subject, how do you calculate how much energy a virtual particle can borrow?, if that makes any sence...
