Black Hole Formation in Proton-Proton Collisions

Click For Summary

Discussion Overview

The discussion centers on the potential for black hole formation during proton-proton collisions, particularly in the context of high-energy physics and the implications of extra dimensions. Participants explore theoretical probabilities and past proposals related to this phenomenon.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • Some participants suggest that there is a probability of black hole formation in ultra high energy proton-proton collisions.
  • One participant references historical ideas about extra dimensions affecting gravity, proposing that such dimensions could lead to stronger gravitational effects at high energies, potentially allowing for microscopic black hole creation.
  • A participant mentions the lack of observed black holes at the LHC and notes that many consider the associated theories to be speculative.
  • Links to original articles and reviews are provided to support the discussion, indicating past research on black hole production and extra dimensions.

Areas of Agreement / Disagreement

Participants express differing views on the likelihood and theoretical basis for black hole formation in proton-proton collisions, with no consensus reached on the validity of the ideas presented.

Contextual Notes

The discussion references speculative theories regarding extra dimensions and their implications for gravitational strength, but does not resolve the uncertainties surrounding these concepts.

Why do you think that this can happen?
 
i'am only talking about probablities so in ultra high energy collisions i think there is a probability of formation of black holes
 
Maybe you're thinking about the ideas from about 10 years ago where it was proposed that if there are extra dimensions which only affect gravity, gravity can be much stronger at high energies/small distances. For some values of the size of the extra dimensions there was a possibility that the LHC reached this energy and that the colliding protons would create a microscopic black hole.

This is one of the original articles examining BH production at the LHC:

This is one of the articles which proposed the extra dimension-scenario:

Of course, there hasn't been found any black holes at the LHC and many probably agree that these ideas were quite speculative.

Here is a review from the Particle Data Group on searches for extra dimensions:
