Micro black holes, millions / billions of years?

Click For Summary

Discussion Overview

The discussion revolves around the concept of micro black holes, particularly in the context of their potential creation at the Large Hadron Collider (LHC) and the implications of their stability and longevity. Participants explore theoretical scenarios regarding the behavior of micro black holes, their interaction with Earth, and the conditions under which they might exist.

Discussion Character

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

Main Points Raised

  • Some participants suggest that micro black holes, if created at the LHC, could potentially last for millions or billions of years without causing harm, depending on their stability and location within Earth.
  • Others argue that micro black holes are believed to evaporate almost immediately and none have been confirmed to be created at the LHC.
  • A participant posits that if a micro black hole were to exist at the gravitational center of the Earth, it would remain stationary without consuming matter, while an off-center position could lead to oscillation and possible erosion of the Earth's core.
  • There is a discussion about the size of the black hole and its ability to capture matter, with some suggesting that a black hole at LHC energy levels would rarely interact with electrons or hadrons.
  • Concerns are raised about the implications of a black hole growing in size and the potential for it to eventually consume the Earth if it were to absorb matter at a sufficient rate.
  • Participants also mention that the creation of stable black holes would require energies far beyond those achievable at the LHC, and discussions reference hypothetical scenarios involving additional dimensions.

Areas of Agreement / Disagreement

Participants generally disagree on the longevity and stability of micro black holes, with some asserting they could last for extended periods while others maintain they would evaporate quickly. The discussion remains unresolved regarding the implications of their existence and behavior within Earth.

Contextual Notes

Limitations include the speculative nature of the scenarios discussed, dependence on theoretical models regarding black hole creation and stability, and the lack of empirical evidence for the existence of micro black holes produced at the LHC.

Another scenario is black holes created at big bang time that have evaporated down to asteroid size.

Ah, I see that our LHC friend had a "small problem" technique I allows me to
