Discussion Overview

The discussion revolves around theories related to black holes and their potential role in the creation of universes, particularly focusing on concepts like Cosmic Natural Selection. It explores questions about black hole mergers, the implications of creating tiny black holes in particle accelerators, and the angular momentum of the universe.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants propose that universes may "reproduce" through black holes, suggesting a connection between black holes and the conditions necessary for life.
  • There is a question about the outcome of merging two black holes, with one participant stating it results in a larger black hole and gravitational radiation.
  • Concerns are raised about the feasibility of intelligent life creating tiny black holes in particle accelerators and whether such black holes could lead to the evolution of life-supporting universes, with a later reply noting the need for verification of these concepts.
  • Participants discuss the universe's net angular momentum, with some suggesting current measurements indicate it does not possess net angular momentum, while others propose that gravity might be a manifestation of angular momentum.
  • One participant references Cosmic Natural Selection, attributing it to professor Smolin and linking it to loop quantum gravity.
  • There are comments on the potential impermanence of artificially created micro black holes, which may evaporate too quickly to be observed.

Areas of Agreement / Disagreement

Participants express differing views on the implications of black holes for universe creation and the nature of angular momentum in the universe. The discussion remains unresolved, with multiple competing perspectives presented.

Contextual Notes

There are limitations regarding the verification of the existence of certain phenomena discussed, such as the creation of new universes from black holes and the nature of gravity in relation to angular momentum.

There is a theroy that universes "reporduce" through black holes, and that part of the criteria that requires this also by coinsidence produces conditions that make life possable.

Discussion questions: What happens if two black holes merge?
If intellegent life creats many tiny black holes in particle accelorators, than universes would evolve to support life, is that probable?
Does the universe have net angular momentum, most black holes do?

You get a bigger black hole and a lot of gravitational radiation.

Until we can verify that such things even exist and that black holes actually do spawn new universes, that question is unanswerable.


Does the universe have net angular momentum, most black holes do?

As best we can measure right now, it doesn't.
 
The theory you are referring to is known as Cosmic Natural Selection and is most notably associated with professor Smolin, whose more mainstream work concerns loop quantum gravity.
 
Even if u manage to create artificially a micro mass black hole using accelerators in the future, u won't notice its pico second presence before it evaporates..
With the LHC(CERN) slated to be in place in 2007, ull witness some of the most interesting particle discoveries ever! and confirmation of super-symmetry theory would be one of them..

Unless what we call gravity is "really" angular momentum.
